Here in the Northwest, getting required winter weather can be a problem as the northerly bulbs often diminish quickly without enough cold. The best example I've seen are tulips: I plant them in pots so I can keep them safe from the marauding deer. Those that are exposed, and freeze (we sometimes do not get a hard freeze) are larger and brighter, and live longer than those who do not. My galanthus as well as the crocus tomisii all sprout in autumn then go dormant for the winter with their noses freezing solid to resume their growth in spring. They never seem to put up their flower stalks until the ground is warm enough so in some years the tops of the leaves are nibbled off but not the growing stalks. The need for winter freeze is not only true for geophytes: peaches and apples are another example ... the old varieties need a certain amount of frost days or they do not perform well, so new varieties have been developed for warmer winter climates.

" 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.
