Odp: Galanthus hardiness

Dear Linda, 

I can imagine, clones of G. nivalis may differ in hardiness. Old "Flora Pleno" is hardy in my zone 6. My neighbours have a probably sterile single clone forming large clumps that have to be many years old. This species grows also wild in Poland. Certainly, deep frozen ground is not a problem for this species, though there may be a limit of temperature the bulb would survive. A lot depends on the snow cover you have in your part of Canada. If you have stable snow cover and it is reasonably 
thick (when you confront it with minimum temperatures) - G. nivalis should survive winter.

In my unstable winter climate G. nivalis have one very important feature - it starts vegetation LATE thus late severe frosts do not hit the leaves over the ground - what is the case in many other snowdrop species (woronowii, elwesii).

Two or three suggestions:
1. You may try very deep planting - 20 cm deep (may be more) should not be a problem for this tiny bulb
2. Plant as early as possible
3. My observation is that though snowdrops bulbs survive "dry shipment" it takes several years for them to regenerate. My suggestion is to buy them growing in pots, wait until dormant and plant deep enough.
