Crocus 2015

When gardeners in the U.K. lost bulbs during the winter, I remarked on the PBS list that bulbs themselves are not very hardy, and the small volume of soil in which they're growing, in pots, making them particularly vulnerable. Galanthus bulbs, say, are only hardy to about -10C. I first read this in The New Plantsman, and it sounded counterintuitive, to say the least, but it explained the constant failure of seed-raised calochortus here. The seed germinates; I have a lawn of calochortus seedlings in each pot; the pots are them left outside the following winter, and there are no calochortus the next spring. 

This went on for years until I read the article (can't find it now) and realized that a calochortus bulb might be hardy in a pot to -10C, but not to -30C. (Winters here are a little chillier than those in Scotland....) So the seedlings are planted in the ground, where the larger volume of soil keeps them much warmer. 

So, anyway, since I don't have much experience growing crocuses from seed, and it's an effort getting seed when it's available, do you think 25€ is too much for a single bulb? I'd need at least two of each, of course, but the dog needs his steak, too.
