Carolyn’s Shade Gardens Goes International

Posted in bulbs for shade, snowdrops, winter, winter interest with tags , , , , , , , , , , , , on February 3, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

The BBC News Magazine was hours away from publication when they emailed to request a photo of me with snowdrops.  My husband and I had a quick photo shoot and this is what we came up with.

We interrupt the regularly scheduled flow of posts on this blog with breaking news.  The owner of Carolyn’s Shade Gardens is prominently featured in the BBC News Magazine lead article for February 2 entitled “Snowdrop Fanciers and Their Mania”. 

All kidding aside, I couldn’t be more thrilled.  I am in the company of Matt Bishop and John Grimshaw, two of the authors of the “snowdrop bible” Snowdrops: A Monograph of Cultivated Galanthus, and Chris Ireland-Jones, the owner of the famous English snowdrop nursery Avon Bulbs.  You know what a snowdrop fanatic I am so this is the ultimate compliment.  To read the article (I am in the second half), click here.

Second Annual Snowdrops & Other Winter Interest Plant Seminars

Charles Cresson pointing out some of his very unusual snowdrop cultivars to last year’s seminar attendees.

I am very excited that winter interest plant expert and gardener extraordinaire Charles Cresson has agreed once again to give seminars on Snowdrops and Other Winter Interest Plants just for my customers.  The seminars will be limited to 20 people each and will take place in his amazing Swarthmore garden, Hedgleigh Spring.  The brochure telling you the details and how to sign up is here.  If you are a local gardener and interested in attending, I encourage you to email immediately because I expect these seminars to sell out.  For a complete description of the 2011 seminars with many photos, click here.

 

Since this post is about all things snowdrop, I thought I would show you the first snowdrops to bloom in my garden in 2012:

The very first snowdrop cultivar to open in my garden in 2012: ‘Kite’.  Notice the very long outer segments (petals).

 

Second to open was Galanthus plicatus ‘Augustus’ with its striking puffy rounded and quilted outer segments.

‘Magnet’ is open and swaying in the breeze on its unusually long and thin flower stems (pedicels).

The double common snowdrop ‘Flore Pleno’ is blooming even though it is usually one of the last snowdrops to open in the middle to end of March.

The aristocratic snowdrop ‘Atkinsii’, said to resemble the pearl drop earrings of Elizabeth I, is also flowering.

The common snowdrop, G. nivalis, is blooming a few weeks early.  I shot this picture to document the date they opened and had a funny feeling that something wasn’t right.  When I uploaded the photos to the computer I realized the plants in the front have four outer segments instead of three—very interesting.

The giant snowdrop, G. elwesii, has been flowering on and off since November, but this patch just opened this week.

I avidly read the Galanthus threads on the Scottish Rock Garden Club forum where galanthophiles from all over the world meet to obsess about snowdrops.  I highly recommend this forum if you are interested in snowdrops and want to learn more.  The forumists are some of the most knowledgeable galanthophiles around but very welcoming and eager to share their passion.  Several of them commented on the varied markings on the giant snowdrops pictured above which got me outside with my camera to record the marks.  Here is what I found:

Every flower in this collage is the same species, G. elwesii, and yet the green marks on the inner segments are all different, from the small single green mark on the middle  right flower to the mark that looks like a mustache and eyes in the middle of the bottom row.  Although I realize this will not excite most gardeners, at least everyone can see the amazing variety.  And variety is the spice of life.

 

 

I have recently been honored with the Versatile Blogger Award by four different blogs, and I want to thank them for the accolade.  I try to make my blog posts varied and yes versatile (able or meant to be used in many different ways), and I am glad that my efforts are appreciated.  I am not following the award rules, but instead letting you know who gave me the award in hopes that you will visit their blogs.  Here are the links and some information to entice you to visit them:

Graphicality–UK:  Helene is a very accomplished author.  You might want to check out her recent post on the book she published with her lovely photos of Kew Gardens.  Her current post talks about US grey squirrels invading Britain.

Green Place:  Sheila is in Chapel Hill, NC, and reflects on spirituality, nature and gardening.  She and I also share a love of Maine islands.

The Amateur Weeder:  For a very different perspective, Lyn gardens in Australia and her blog produces “seedlings from the mind of an inconstant gardener.”  I particularly liked her recent post called Designed by Nature.

Women and the Garden:  Patty writes about “the history of the garden and the various roles women played in that history,” and it is  all absolutely fascinating.  She doesn’t post often, but when she does you don’t want to miss it.  Her latest post is on Pomona, the roman goddess of fruiting trees and orchards.

Chanticleer in Winter: Texture

Posted in garden to visit, landscape design, winter, winter interest with tags , , , on January 28, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

Chanticleer’s Teacup Garden in May

Chanticleer is a unique public garden in Wayne, Pennsylvania, U.S., which I have profiled in three previous articles.  The first, Chanticleer Part 1: A Pleasure Garden, gave an overview of this one-of-a-kind horticultural destination.  The second, Chanticleer Part 2: Garden Seating, focused on the huge variety of thoughtful seating areas in the Chanticleer gardens.  The third, Chanticleer Part 3:  Through the Seasons, showed the gardens as they evolve through spring, summer, and fall.

 

The Teacup Garden in January

To complete my series on Chanticleer through the year, I received special permission to visit the garden during the winter months when it is closed to the public.  As you can see from the photo above, all the “toys” are put away and most of the flowers and foliage are gone.  But the minute I stepped into the garden, the word TEXTURE appeared before me as if it was outlined in neon lights.  I have never had such an exciting visit to this garden because I saw it in a whole new way, and I hope I can communicate that to you.

I always admire the elegant mature trees when I visit, but without their leaves or any flower gardens to distract me, they really stood out.

Texture was also provided by smaller plants, but not the way I expected:

 


 



Hardscape, always a huge part of Chanticleer’s elegance and beauty, really dominated my visit:


 

 

 

The attention to detail in the paths, always a hightlight for me, was easier to see and appreciate:

I decided not to add captions to the photos in this post, but if you want more information just run your cursor over the photo.  The location of the Lady in the Lake is secret so you will have to find her for yourself.

I want to thank Bill Thomas, Chanticleer’s Director, for making this visit possible, Fran DiMarco, Administrative Assistant, for arranging it, and Joseph Henderson, Horticulturalist, for providing some needed conversation in the sun so I didn’t freeze to death.  I have been promised a visit in the snow, and I might take them up on it if we ever get any of the white stuff.

New Snowdrops for 2012

Posted in New Plants, Shade Perennials, snowdrops, winter, winter interest with tags , , , , , , , , , , , , , , , , , , , , , on January 19, 2012 by Carolyn @ Carolyns Shade Gardens

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops within the US.  For catalogues and announcements of local events, please send your full name, mailing address, and cell number to carolyn@carolynsshadegardens.com and indicate whether you are interested in snowdrops, hellebores, and/or hostas.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

Who said all snowdrops look alike?  Some of my favorites: top row, L to R, ‘Wendy’s Gold’, ‘Blewbury Tart’, ‘Hippolyta’, ‘Flore Pleno’; middle, ‘Jaquenetta’, ‘Merlin’, ‘Lady Elphinstone’, ‘Augustus’; bottom, unknown, ‘Ophelia’, G. plicatus subsp. byzantinus, ‘Lady Beatrix Stanley’.

.

Our current snowdrop catalogue is on line here.

.

This article includes photographs and colorful descriptions of the 5 new snowdrops I am offering for sale in my 2012 Snowdrop CatalogueFor entertaining descriptions of most of the remaining 13 varieties offered in the 2012 catalogue, click here.

The hundreds of snowdrop cultivars out there range from a classic like ‘Atkinsii’ pictured above to…(see next photo)

In Snowdrops or The Confessions of a Galanthophile, I described my transition from someone who grows snowdrops to someone who is obsessed with them.  In Snowdrops: Further Confessions of a Galanthophile, I explained that most snowdrop cultivars can be appreciated as much for their colorful history as for their ornamental characteristics.  That history is contained in Snowdrops: A Monograph of Cultivated Galanthus by Matt Bishop, Aaron Davis, and John Grimshaw (Griffin Press 2006), commonly called the “snowdrop bible”.

Galanthus nivalis 'Blewbury Tart' at Carolyn's Shade Gardens…this crazy, modern double cultivar, ‘Blewbury Tart’, which looks like it’s having a bad hair day (I love it!).

The information in Snowdrops is not only interesting but also crucial to keeping straight all the available snowdrops.  Snowdrops describes over 500 cultivars, and the authors admit that it is now out-of-date, and a second volume is required (for details on Snowdrops 2, click here).  Snowdrops description of the cultivar along with the actual origin of the snowdrop plant in question both contribute to its provenance: the history of its ownership documenting its authenticity.  If a collector is purchasing an expensive plant, provenance is very important.

Snowdrop prices range from the very affordable (but no less desirable) common snowdrop, G. nivalis, pictured above with Italian arum and snow crocus, to…(see next photo)

…the highly collectible (with a price to match) ‘Wendy’s Gold’.

‘Brenda Troyle’, a new snowdrop from Charles Cresson in my 2012 catalogue, is a perfect example of how this works.  True ‘Brenda Troyle’ is a vigorous snowdrop admired for its well-proportioned, rounded flowers with flared and cupped outer petals (segments) and a strong fragrance of honey.  It received an Award of Garden Merit from the Royal Horticultural Society in 1960 for “outstanding excellence for ordinary garden decoration or use.”  Customers who attended Charles Cresson’s snowdrop seminars last year loved it.

Charles Cresson’s authenticated ‘Brenda Troyle’

But Snowdrops explains that ‘Brenda Troyle’ is very mixed up in the trade.  In fact, it is even unclear whether it was named after a character in Sir Walter Scott’s novel The Pirate or a staff member at an Irish nursery.  In cases like this, it is very important that the snowdrop display the desirable characteristics of the cultivar as Cresson’s stock does.  It is equally as important that the original stock was purchased from a reputable source and kept labeled since its purchase.  Charles got his plants from a bulb company started by the venerable Hoog family of Van Tubergen fame and conserves his whole snowdrop collection with the utmost care.

Galanthus ‘Tiny’

‘Tiny’ is a snowdrop that does not suffer from an identity crisis as Snowdrops states that almost every galanthophile in the U.K. grows it.  It is a diminutive form of the common snowdrop, G. nivalis, easily distinguished by its narrow leaves and elfin stature.  It is quite charming in a clump, which develops rapidly with this vigorous cultivar.  It also flowers later, extending the snowdrop season into late spring.

The subspecies byzantinus of G. plicatus is easily distinguished from subspecies plicatus by the two marks on its inner segments.


Unique provenance adds significantly to the desirability of a snowdrop as is the case with the Turkish snowdrop, Galanthus plicatus subsp. byzantinus.  This subspecies has beautiful wide pleated leaves and lovely plump flowers joined in an elegant overall habit.  It comes from a small area in northwestern Turkey, but is uncommon even there.  Subspecies byzantinus is an exceptionally good form of G. plicatus, hard to come by even in the U.K.

The elegant habit of G. plicatus subsp. byzantinus.

But the part of its provenance that is really exciting is that these plants originated from one of the most celebrated and important American snowdrop collections, the gardens at Winterthur.  As Henry Francis du Pont added plants to Winterthur, snowdrops became a focus.  In the 1930s, he purchased the parents of these very bulbs from Barr & Sons, a renowned bulb house that operated in Covent Gardens, London, from 1882 to 1956.  When Charles Cresson worked at Winterthur in the early 1990s, he was given plants of this unique snowdrop, and we are offering the offspring of those plants in the 2012 catalogue.  Now that’s provenance!

The Greatorex double ‘Hippolyta’ (photo by and used with the permission of Paddy Tobin).

The final two new snowdrops were both hybridized in the mid-twentieth century by the legendary but enigmatic snowdrop breeder Heyrick Greatorex and are known as Greatorex doubles.  Snowdrops makes an unflattering reference to a story that he spent World War II in a local pub.  However, further research reveals that, in addition to serving in WWII, he fought in World War I, was wounded at Lagincourt, and received the Victory and British Medals—a very distinguished record indeed.  If you would like to read more about him, click here.

Galanthus 'Hippolyta' photo Paddy Tobin‘Hippolyta’ (photo by and used with the permission of Paddy Tobin)

‘Hippolyta’ is the shortest of the many Greatorex double snowdrops, which Heyrick Greatorex developed by crossing the double common snowdrop, G. nivalis ‘Flore Pleno’, with the species G. plicatus to create large and vigorous plants.  He named them after characters in Shakespeare’s plays, Hippolyta appearing in A Midsummer Night’s Dream.  Although some of the Greatorex doubles are confused, ‘Hippolyta’ consistently produces neatly doubled, rounded flowers, combining a tightly compact inner rosette with cupped and flaring outer petals (segments)—a charming arrangement.  It received an Award of Garden Merit from the Royal Horticultural Society in 1970.

 

The Greatorex double ‘Dionysus’

The final member of the five new snowdrops in my 2012 Snowdrop Catalogue is ‘Dionysus’, also a member of the acclaimed series of double snowdrops developed by Heyrick Greatorex (although not a Shakespeare character).  ‘Dionysus’ is one of the taller and earlier flowering doubles in this series.  It has fewer inner segments  than other Greatorex doubles, and  they feature a large, deep green, inverted heart-shaped mark.  Evidently Heyrick Greatorex described ‘Dionysus’ as one of the best of his doubles for cultivation in the open garden.  Charles got his bulbs from the well known Oregon bulb authority Jane McGary.

Obviously, I find everything about snowdrops fascinating and hope I have communicated some of my infatuation to you.  If you are in the U.S. and want to order from the catalogue, just follow the directions for mail order.

I have had this gorgeous double purple hellebore in my garden for several years but it has never bloomed this early.  Photo 1/7/12

It is the middle of the month and time to participate in Garden Blogger’s Bloom Day hosted by May Dreams Gardens (link available on December 15) where gardeners from all over the world publish photos of what’s blooming in their gardens.  I participate because it is fun and educational for me to identify what plants make my gardens shine at different times of the year.  This month I hope that my nursery customers and blog readers will get some ideas for plants to add to their own gardens to extend their season through winter.

My garden is located in Bryn Mawr (outside Philadelphia), Pennsylvania, U.S., in zone 6B.


‘Mrs. Betty Ranicar’ is usually one of my first hybrid hellebores to bloom but this is early even for her.

Last January, the whole garden was under snow, and I didn’t even participate in GBBD.  This year couldn’t be more different with 7 days in the 50s (10C) and 6 days at 60 degrees (16C) or above since December 15.  Frankly, I find it extremely worrisome, but it means that I didn’t have to go searching for plants peaking between December 15 and January 15.  There are a few other plants worth featuring, but my hellebores are all blooming early so I call this post Hellebores on Parade.  For the benefit of my customers, I will note which hellebores will be for sale at Carolyn’s Shade Gardens (CSG) this spring.

 

‘Pink Tea Cup’ has the best pink color of any hybrid hellebore and was the first to come into bloom this season ( for sale at CSG this spring).  Photo 1/9/12

 

‘Jacob’ Christmas rose just keeps going and going with new white flowers appearing and mixing with the older pink flowers for a gorgeous effect, see below (for sale at CSG).  Photo 12/31/11

 

‘Jacob’ Christmas rose with Camellia x ‘Winter’s Joy’.  Photo 1/2/12

Flowers are emerging on the hellebore species cross ‘HGC Pink Frost’ (for sale at CSG).  Notice the dark red to burgundy highlights on the leaves and stems and the amazing color of the buds.  As noted in Cutting Back Hellebores, I leave the foliage on to make a nice backdrop for the flowers.  Photo 12/31/11

 

‘Praecox’ Christmas rose is also blooming at least a month earlier than usual.  Photo 12/31/11

 

The hellebore species cross ‘HGC Winter’s Song’ is now fully in bloom.  Photo 1/10/12

The rare species Helleborus dumetorum (no common name) continues to bloom (for sale at CSG).  It is deciduous so all the “leaves” in the photo are actually flower bracts.  The leaves will come up later.  Photo 12/31/11

This beautiful, pure white, outward-facing hellebore called ‘Snow White’ (aka ‘Snow Bunting’) is an extremely rare cross between hybrid hellebore and Christmas rose—something that was thought to be impossible (for sale at CSG).  Photo 1/9/12

 

The lighter chartreuse buds of bearsfoot hellebore, H. foetidus, are becoming more prominent and will remain ornamental through May (for sale at CSG).  Photo 1/10/12

 

Helleborus x "Double Purple"Another look at the hybrid hellebore “Double Purple” (for sale at CSG).  Photo 1/7/12

My new favorite this year, hellebore species cross ‘HGC Cinnamon Snow’ (for sale at CSG).  I like it so much that I decided to put it in a basket by my front door.  Photo 1/9/12

There are some other plants looking great in my garden besides hellebores.  Most of the fall-blooming camellias still have viable buds but no flowers open to show you.  They will continue to bloom if the weather cooperates.  Here are the non-hellebore stars:

My un-named Korean Camellia japonica, which blooms in the spring and fall, continues to produce flowers.  Photo 1/9/12

Camellia x ‘Elaine Lee’ also has buds, and look at those shiny leaves.  Photo 1/10/12

Camellia x ‘Winter’s Joy’ has been flowering since October and is still covered with buds but none are open right now.

The buds on my variegated winter daphne, D. odora ‘Aureomarginata’, are coloring up early.  It is the sole survivor of five shrubs I put in this spring.  Although I gave them excellent drainage, they just couldn’t tolerate all the rain we had in August and September.  One by one they wilted from too much water and died, while this one remained healthy.  Photo 1/9/12

If we have cold weather, winter jasmine, Jasminum nudiflorum, blooms in February, but right now it is opening flowers continuously.  Photo 1/10/12

Galanthus elwesiiThe only snowdrop in bloom right now is the giant snowdrop, Galanthus elwesii (for sale at CSG).  Photo 1/9/12

My fall-flowering snowdrop ‘Potter’s Prelude’ has finished blooming, but I wanted to show you its beautiful leaves (for sale at CSG).  Photo 1/1/12

On New Year’s Day, my husband and I went walking in the Pinetum at the Haverford College Arboretum, a wonderful local treasure.  We saw two unusual conifers with great texture that I wanted to share:

 

Longleaf pine, Pinus palustris, is native from Virginia to Texas but is not usually found around here.

 

I love firs, and the texture of this Algerian fir, Abies numidica, really stood out.

I dedicate this post to Bob Stewart, my friend and horticulturalist extraordinaire, who died on December 16, 2011.  Bob and his wife Brigitta started the amazing nursery Arrowhead Alpines in Fowlersville, MI.  If you haven’t visited their site, you should by clicking here.  Bob will be greatly missed.

March GBBD: The Philadelphia International Flower Show

Carolyn’s Shade Gardens is a retail nursery located in Bryn Mawr, PA, specializing in showy, colorful, and unusual plants for shade.  The only plants that we ship are snowdrops and miniature hostas.  For catalogues and announcements of events, please send your full name, location, and phone number (for back up use only) to carolyn@carolynsshadegardens.com.  Click here to get to the home page of our website for catalogues and information about our nursery and to subscribe to our blog.

It is time to walk around your garden again and assess what you need to add to make the beginning of spring an exciting time in your landscape.  Do you need more early-blooming hellebores, to give you a reason to go outside?  Could your garden benefit from flowers that bloom in early March like hardy cyclamen, snow crocus, or snowdrops to relieve the gray?

Make a list and take photographs so that when you are shopping this spring you know what you need and where it should go.  I know it’s still pretty cold outside, but you never know what you might find to end the winter doldrums like the beautiful double-flowered hellebore (pictured above), which I discovered during my own  inventory.  More photos of my blooming plants are included at the end.

As you entered the 2011 Philadelphia International Flower Show, you walked under a very large replica of the lower half of the Eiffel Tower

If you need ideas, there is no better place to go in the mid-Atlantic this time of year than the 2011 Philadelphia International Flower Show.  It is the largest indoor flower show in the world.  This year’s theme was “Springtime in Paris”, and the designers went all out.  I sent photos of some of the weirder stuff to Cheri at Along Life’s Highway The Yard Art Game, and you can see them by clicking here.  But I found the following displays and entries inspirational for my own garden:

There is nothing more beautiful than an individual well grown plant

A new idea for my sedum displays, which are fantastic in containers

Inspiration to upgrade my troughs

I need an elegant metal gate for my walled compost area

Simple can be very beautiful

Today is Garden Blogger’s Bloom Day for March when gardeners around the world show photos of what’s blooming in their gardens (follow the link to see  photographs from other garden bloggers assembled by Carol at May Dreams Gardens).  Here are  some more highlights from my mid-March stroll through Carolyn’s Shade Gardens:

Eranthis hyemalisWinter aconite, Eranthis hyemalis

Scilla mischtschenkoanaVery early-blooming Tubergen squill, Scilla mischtschenkoana

My original snow crocus, Crocus tommasinianus, which is rodent resistant, has multiplied into thousands of plants

Winter jasmine, Jasminum nudiflorum, has no scent but makes up for it by blooming so early

Winter-blooming hardy cyclamen, Cyclamen coum ‘Rose’

I want to include hundreds of hellebore photos but am limiting myself to some really special plants:

The rare species Helleborus purpurascens

The flower of Helleborus purpurascens

Another even rarer species Helleborus viridis: inspired by Laura at PatioPatch, I am dedicating this flower to the people of Japan because green is the color for hope

A cross between Corsican hellebore and Christmas rose, Helleborus x nigercors ‘Honeyhill Joy’

A very beautiful anemone-centered hybrid hellebore where the nectaries have become petal-like (petaloid)

Another petaloid hybrid hellebore

‘Blue Lady’ hybrid hellebore

Hybrid hellebore with picotee markings (darker edges, veins, and nectaries)

A very good yellow hybrid hellebore with maroon nectaries

Some of the thousands of common snowdrops, Galanthus nivalis, which have multiplied on my property since the 1800s:

Common snowdrop with Italian arum, Arum italicum ‘Pictum’

Common snowdrop with Heuchera ‘Creme Brulee’ displaying its winter color

Some of my very special snowdrop cultivars:

Galanthus 'Ophelia'Double-flowered Galanthus ‘Ophelia’

The unusual species with pleated leaves, Galanthus plicatus subsp. byzantinus

Galanthus 'Lady Beatrix Stanley'Galanthus ‘Lady Beatrix Stanley’

Galanthus nivalis 'Blewbury Tart' at Carolyn's Shade GardensThe crazy upward facing double, Galanthus nivalis ‘Blewbury Tart’

“Spring-blooming” hardy cyclamen, Cyclamen coum, sends out its first bud

It is time to walk around your garden again and assess what you need to add to make the end of winter an exciting time in your landscape.  Do you need more early-blooming hellebores to give you a reason to go outside?  Could your garden benefit from flowers that bloom in January and February like hardy cyclamen, snow crocus, or snowdrops to relieve the gray?  Make a list and take photographs so that when you are shopping this spring you know what you need and where it should go.  I know it’s icy outside, but you never know what you might find to end the winter doldrums like the hardy cyclamen (pictured above), which I discovered during my own chilly inventory.

If you need ideas, visit local arboretums and gardens.  I always find a trip to Winterthur, an elegant and intimate public garden in Delaware, highly inspirational and informative.  Starting March 1 when Winterthur opens for spring, the area of the gardens known as the March Bank erupts into bloom with tens of thousands of snowdrops, adonis, winter aconite, snow crocus, early scillas, glory-of-the-snow, spring snowflake, and early daffodils.

Today is Garden Blogger’s Bloom Day for February when gardeners around the world show photos of what’s blooming in their gardens (follow the link to see  photographs from other garden bloggers assembled by Carol at May Dreams Gardens).  Here are a few more highlights from my mid-February stroll through Carolyn’s Shade Gardens:

Very early-blooming double white hellebore, Helleborus x hybridus ‘Mrs. Betty Ranicar’

Bearsfoot hellebore, Helleborus foetidus, was waiting under the ice

Sweetbox, Sarcococca hookeriena var. humilis, prepares to perfume the garden

‘Jacob’ Christmas rose, Helleborus niger ‘Jacob’, began blooming in October and has waited patiently under the snow and ice for a chance to show its flowers again

The lowly Japanese pachysandra, P. terminalis, forms its flowers the previous season adding winter interest to its evergreen leaves

The flower buds of hybrid hellebores, Helleborus x hybridus, wait for the hard-packed snow to melt, in warmer years they would be in bloom now

Some hybrid hellebores are farther along than others

Giant snowdrop, Galanthus elwesii, was the first flower through the snow in 2011 (see Are Snowdrops Thermogenic?) and was also blooming in December

With our near record-breaking snowfall accompanied by generous doses of ice (see The Joys and Sorrows of Snow), I wasn’t planning on participating in February’s Garden Blogger’s Bloom Day.  But when I grabbed my camera and walked around, there was much to be seen.   In addition to the flowers, there was more than enough views of the destruction of the winter by nature and otherwise.

Snowdrops are some of the earliest blooming flowers in my garden, often popping up through the snow, hence their name.  We all love them for that, but how do they do it?  I have been told several times that they are thermogenic, that is,  that they produce their own heat, and decided to do some scientific research to find out (it can’t all be about pretty photos).

Over 200 years ago, French biologist, Jean-Baptiste de Lamarck, noticed that some flowers produce their own heat.  Since then, scientists have confirmed that some plants can, in fact, generate their own heat, a process known as thermogenesis, previously thought to be limited to mammals, birds, and some flying insects.  These plants are “warm-blooded”.

The poster child for thermogenesis is the eastern skunk cabbage, Symplocarpus foetidus, which is native to most of eastern North America.  Its flower, pictured below (courtesy of Robert Klips, Ohioense: Bob’s Brain on Botany, March 8, 2010), heats up to melt the snow producing little circles all over the woods in late winter.  It does this primarily to generate and disperse its floral scent to attract pollinators.  In this case, the scent is rotten meat and the pollinators are flies and beetles.  Secondarily, it rewards the insects by providing them with energy directly as heat rather than indirectly as nectar and pollen.

This is no small feat.  Skunk cabbage flowers can heat up to 59 degrees F (15 degrees C) when the ambient temperature is 5 degrees F (-15 degrees C).  They can also thermoregulate, adjust their temperature, to maintain a constant setting as the ambient temperature changes.  If the outside temperature gets too low, they will switch off their heat entirely until things warm up.  They also switch off the heat once they have been pollinated.

To perform thermogenesis, skunk cabbage uses as much metabolic energy as a small rodent or a hummingbird and employs a unique respiratory process, which is more similar to animal metabolism than plant metabolism though biochemical rather than nervous system based.   The exact nature of this process is unknown.  For those of you with a scientific bent, I have included a graph below taken from  a scholarly treatise on the subject, Temperature Regulation by Thermogenic Flowers (Plant Physiology Online, Sept. 2006).

Graph of oxygen consumption and heat production by skunk cabbage in various ambient temperatures

But, now that you understand thermogenesis, back to the question at hand: are snowdrops thermogenic?  The short answer is I don’t know.  Various sources say that they are, but the statements seem to be based on hearsay.  I could find no scientific studies backing them up.  I posted the question on the Pacific Bulb Society forum, the Scottish Rock Garden Club forum, and to friends at Longwood Gardens, and no one could confirm that snowdrops are thermogenic.  So I present my own “scientific study” of the process.

February 21, 2010, at Carolyn’s Shade Gardens, three tiny islands are appearing in the snow

As you know from my previous post, The Joys and Sorrows of Snow, we had record snowfall during the winter of 2009-2010.  By February, my whole garden was covered by a deep, thick, hard layer of snow.  Looking out on the landscape in the photo above, there was absolutely no melting going on except in three small areas.  What is happening in those little circles?  Let’s look closer:

Giant snowdrop, Galanthus elwesii, melting through the snow

 

And even closer:

My observations prove nothing scientific, but they do indicate that something is going on.  And I like to think that one of my favorite plants, snowdrops, which inspire such intense interest in many gardeners, also produce their own internal excitement.

The Joys and Sorrows of Snow

My office, an historic carriage house, in winter

I love snow.  I am not sure that my garden is ever more beautiful than with a dusting of snow highlighting every branch and stem.  And to me there is really nothing uglier, in the garden anyway, than snowless frozen soil or mulch surrounded by the fences and houses that I can’t see when the leaves are on.

My “signature” bird house in winter

Ice is very beautiful too (I can hear the groans, but if you can ignore the sounds of branches breaking and just stare at the ice, it is lovely.  On second thought, maybe you should only view ice from inside the house.)

My upright coral bark maple, Acer palmatum ‘Sango-kaku’: more vertical Japanese maples fare better in  snow and ice than weeping forms

White pine, Pinus strobus, is not suitable for ornamental landscapes as explained below

Winterberry holly, Ilex verticillata ‘Red Sprite’, looks beautiful encased in ice

Here in southeastern Pennsylvania, we had record snowfall during the winter of 2009-2010 with 70 inches.  The previous record was 1995-1996 with 66 inches, but over three feet came in one blizzard so there wasn’t consistent cover.  Before that you have to go back to 1898-1899 with 55″ inches.

My house, Wayside Cottage, the old estate gardener’s dwelling.

As the snow melts and temperatures warm, we get fog

During 2009-2010, the ground was covered with snow almost the whole winter, which hasn’t happened in quite a while here.  Snow cover is very important for plants, especially when the temperatures dip down into the single digits.  We are in USDA hardiness zone 6b with an average annual minimum temperature of 0 to -5 degrees F (-18 to -21 degrees C).  Snow insulates plant roots and keeps them at an even temperature, preventing the freezing and thawing that heaves them out of the ground.  Snow also provides much needed moisture over the winter and especially in the spring as it melts slowly and waters the emerging perennials.

My clump of yellow trillium doubled in size after a snowy winter

Cobra lily, Arisaema urashima, reached new heights

When my perennials came up in the spring of 2010 after the snowy winter, they were spectacular.  Struggling plants were suddenly big and glorious.  Newly planted areas looked well established.  Patches of slow growing woodland ephemerals doubled and tripled in size.  Asian jack-in-the-pulpits that hadn’t come up in years burst out of the ground and were twice their normal height.  I had given them up for dead.  Seeds of rare plants germinated and thrived in my woodland unaided.  I suddenly had a small hillside of the snow white jack-in-the-pulpit Arisaema sikokianum.  Trilliums, dogtooth-violets (Erythronium), and fumewort (Corydalis solida) proliferated in new combinations and colors.  The snow was very good to my perennials.

A new color form of dogtooth-violet, Erythronium, appeared in my woodland

I wish I could say the same for my shrubs and trees.  My very well established winter daphnes, Daphne odora, and my February daphne, Daphne mezereum, were bent to the ground by snow and falling limbs.  Although I righted them, they all suddenly wilted and died in the spring.  I think once the roots are damaged or disturbed, they are not resistant to pathogens and quickly succumb.  That may be the origin of what is known as sudden-daphne-dieback.

Damaged weeping Japanese maple, Acer palmatum dissectum: upright forms of Japanese maple fared better, they just bent to the ground and sprang back up

Voles, protected from my cats by the snow, ate my rare tree peony purchased from the old Heronswood many years ago.  I also lost my Chinese redbud, Cercis chinensis, both my white and my gold variegated Kousa dowoods, Cornus kousa ‘Wolf’s Eye’ and ‘Sunsplash’, my yellow rugosa rose, Rosa rugosa ‘Topaz Jewel’, and an old native rhododendron that came with the property in 1983.  My woody plants did not like the snow.

Split native ‘Forest Pansy’ redbud, Cercis canadensis ‘Forest Pansy’: it should probably be grown as a single trunk

You may be saying, wow she really should be growing native trees and shrubs, and she wouldn’t be having all these problems, but you would be wrong.  The winter of 2010-2011 is gearing up to exceed last year in snowfall with 50 inches already and more storms in the forecast.  During last week’s 18 inch storm, which included sleet, I lost a large specimen ‘Forest Pansy’ redbud, Cercis canadensis ‘Forest Pansy’ (photo above), an old flowering dogwood, Cornus florida, a red spruce, Picea rubens (photo below),  and a lot of my large white pine, Pinus strobus (photo below), all native plants.  Apple trees, a very old specimen weeping Japanese maple, Acer palmatum dissectum (photo above), and my Chinese wax shrub, Sinoclaycanthus chinensis, were also severely damaged.  Last night’s ice storm is only adding to the wreckage.

My red pine, Picea rubens, just snapped off

Branches rained down from my white pine, Pinus strobus: white pine is not a good tree for ornamental landscapes because it sheds its lower branches freely, damaging the understory plants

Once I would have mourned the loss of my prize plants.  Now I choose to be more philosophical, learn the lessons inherent in the process (which I have tried to pass on above), and look forward to what new miracles my perennials will present to me this spring—my jack-in-the-pulpits have already risen from the dead.  The glass will be determinedly half full.  As my good friend Kim remarked when I told her about the specimen redbud’s demise: “Think of the opportunities it has opened up for you in the garden!”  I don’t think I can go that far.  I intend to plant another redbud in the exact same spot.

Please tell me in a comment/reply what lessons you have learned from snowy winters.
