I suppose it depends on the winters to which they have adapted. I used 
to live in Fairbanks, Alaska, which is, to put it mildly, cold in 
winter. All winter. I collected wild seeds -- alpine perennials, not 
bulbs -- for my little rock garden there and sowed them immediately in 
pots. Some species germinated immediately, and I left the seed pots 
outdoors under the snow all winter. In spring (late May), when the snow 
melted, they resumed growth. The point of difference here is that they 
were under an average of 60 cm/2 feet of snow that never thawed until 
spring. Temperatures at the soil surface were far warmer than the 
atmospheric temperatures. Of course, rodents are active under the snow, 
but my dogs helped control them (I suspect owls did too), so there 
probably wasn't much danger of their eating the seedlings when they had 
better resources elsewhere. One spring I was very surprised to see 
tomatoes germinating in the vegetable garden from the previous year's 
discarded fruits.

The arctic bulbous species discussed a month or two previously must 
enjoy the same kind of protection, though I wonder about Lloydia, which 
I've seen growing in rock crevices on outcrops that are probably blown 
free of snow. Some garden bulbs from farther south do well in Fairbanks, 
especially Asiatic lily hybrids.

Jane McGary, Portland, Oregon, where winter has been nearly nonexistent 
so far this year.
