Antifreeze plants for Wildflower Wednesday



No winter garden in the Northern hemisphere is ever complete without the delicate little nodding blooms from the little snowdrop bulb (Galanthus nivalis).  I am pleased to say that they have finally started to flower in my garden - though 10 days later than last year.  



 from my garden

Many purists wouldn't refer to Galanthus nivalis as being a native of Britain but it has been recorded here in the UK since the sixteenth century and it grows wild all over the countryside here in Perthshire. 

Nature's  Natural Ice Breaker

They are just perfect for coping with our harsh winters here as the tips of their leaves have been created in such a way that they are hard and can break through the frozen ground - natures natural ice breakers!

Natures Natural Antifreeze

Now you're probably wondering why I used antifreeze in the title of the post today well read on and you'll see what I'm talking about......

When you get winters like our last two in the UK with  temperatures reaching -18C and lower sometimes the cells inside a plant crystallise especially if the plant is in a pot.  Once the plant defrosts the cells rupture and the plant slowly starts to die.  Well that doesn't happen to a snowdrop as it has natural antifreeze in its little leaves.  

Not only that but the alkaloids found in the plants are potential applications for the treatment of malaria and Alzheimer's disease. 

Ultra Violet Markings

The photo below shows the ultra violet green markings on the inner petals that guide the bee to its precious nectar.

Down by the River 

It certainly is adapted to growing in adverse conditions  as the little bulbs along the banks of the river were covered by the flood waters a few weeks ago. Some of them are flowering though not as many as last year as so much silt has come down the river after the land slippage that they are buried underneath the fine sand.

Speaking of the slippage - thankfully the money has been found to start to repair the damage on both sides of the river bank and I was shocked at how extensive the whole recovery operation is.  They seem to be altering the course of the river ever so slightly and slowing down the flow so that the area where the land slipped will be less prone to more erosion.   Within the next month or so the path should be open again!


Away from the diggers further down stream the river looks far more inviting .............

Along the Lade

While along the lade there are little pockets of snowdrops intermingling between cushions of soft green moss, twigs and decaying leaves.

Nature's Natural Themometer

From the photo's in the collage above I can tell you that it was less than 10 degrees C on the day I took those photographs. It was a cool day and the snowdrop blooms were keeping their nectar safe wrapped in those little petals for a reason.   Once the temperature reaches 10C the outer petals start to open wide and release their soft honey scent to attract bumblebees.  The little snowdrop was created to do this as God knew that the bumblebees would never be able to fly in temperatures less than 10C so He enabled the snowdrop to have it's valuable winter nectar larder safe for when the little bees needed it most.

You can read a more extensive post on growing snowdrop bulbs on my Love is Galanthophilia post.

Today I'm submitting this post to Gail's Wildflower Wednesday meme over at Clay and Limestone.

Thank you for taking the time to visit today.

Love is Galanthophilia


Love is ............... Galanthophilia!   It's in the air along with the delicate scent of honey as the Galanthus "Brenda Troyle" snowdrop bulbs begin to flower.  When the winter rays break through our dark thick veil of clouds the little pearl drop pendant flowers begin to open. Single green heart shaped markings are then revealed on the inner petals.  Surely Spring can't be that far away now? 

The little pot of snowdrops are a present from my friend J - the plant explorer.  A few weeks ago he was telling me about one of his trips many years ago to the border region of Turkey and Iran to photograph snowdrops and I just happened to say that I would like to start a little collection so maybe this is the start of Galanthophilia for me!  

For now the little pot is sitting on my kitchen window sill where I can enjoy the little winter blooms and delicious scent of honey.  There are 2 snowdrops in the little pot though they didn't cost £357 per bulb that a rare Galanthus plicatus EA Bowles sold for on ebay.  These ones seem to be around £4.50 each plus p+p on the internet though my little pot of Brenda Troyle came from a scottish garden. This year the National Trust is tagging their snowdrops at Anglesey Abbey, Cambridgeshire to prevent them from being snatched and then sold on as it is illegal in the UK to collect them from the wild.


Planting in containers in the soil

Many times I pierce bulbs with my garden trowel or fork by accident so this time I'm going to be alot more careful with the planting.   I have some old aquatic mesh pots in the garage and once the bulbs finish flowering I'm going to replant them in one of these  with John Innes No 3 compost (they are hungry little plants) and then plant the whole container in the soil  in a shady spot under a shrub. The roots from the bulbs will still be able to grow through the mesh in the pot to obtain moisture and lots of nutrients plus it's added protection from my trowel.  Once in the ground J. told me that they will multiply reasonably quickly and will flower when the bulbs are still quite small young.

Root Damage

Did you know that the old roots of the little snowdrops are very very sensitive to damage and loss of those roots due to transplanting can affect the flowering in subsequent years.  I have always thought that planting snowdrops in the green was best but over at Galanthus.co.uk they say otherwise and that it takes the bulb a whole year to recover before it starts to grow strongly again.  They suggest lifting them in their dormant stage which is in the UK between June and late September.

Pests and Diseases

Snowdrop bulbs are relatively pest free with deer, rabbits and mice not eating them due to the poisonous alkaloids in the leaves and bulbs which probably explains why we have so many drifts of them in the wild around Perthshire. There is one pest  this year I'm going to be on the look out for and that's the Narcissus fly or Greater Bulb Fly (Merodon equestris).  It looks just like a hover fly and is a bumblebee mimic.  In the spring time the adults can be seen feeding on the nectar of dandelions along with other spring flowers.   Even though this fly is most commonly associated as being a pest with daffodil bulbs it has been discovered that snowdrop bulbs can be affected as well.

These photos below from my own garden were taken in May 2011 of the Greater Bulb Fly. (You can read the blog post relating to the Great bulb fly here if you are interested).

As the leaves of the snowdrops are dying down a chemical is released which attracts the flies.  The  little tunnel that has been left in the soil where the green shoot pushed its way earlier to the surface of the soil is where this fly lays its eggs just at the leaf base of the withering leaves.  Once the larvae hatch they burrow into the bulb and start to feed on it over the course of a few months before they leave to pupate in the soil.

How to protect the snowdrop bulbs

The best organic advice I've been given is to rake over the snowdrop bulbs as the leaves are dying down so that the soil fills in around that little tunnel and prevents access to the bulb and to plant them in a shady spot as the snowdrop bulbs in a sunny spot are more susceptible to attack.

So if some of your clumps of snowdrop bulbs are not flowering well or have totally disappeared from a particular area of your garden maybe the snowdrops have been attacked by this fly.

Nature's Calendar 

Hopefully by the end of this week the snowdrops outside in the garden will be flowering.  This year they are about 10-14 days late in flowering compared to last year but this year it has been an exceptional winter.  We said that last year too thinking it couldn't get any worse but it did!. We had a Snow.......... drop visit of another kind this week leaving my husband with about 3 inches to shovel again off the paths and driveway.

It's a little warmer along by the lade and by Thursday the wild ones were glinting in the winter sunshine.

Elsewhere in the UK

If you live in Scotland you can check out the Scottish Snowdrop Festival 2011 to see where some of the great displays will be in your area and The Great British Gardens website  and The National Trust for other parts of the UK.

As I mentioned at the begining of the post - love is in the air and as it's Valentines day I'll leave you with another little heart from my garden.....................
