The patch that's in heavyish soil is also very near a large Alberta 
blue spruce, and the bed would be sucked dry in summer if I didn't 
water it. The site is sunny enough in summer that a shade-loving 
Athyrium ("Japanese painted fern") gets burnt unless I keep the soil 
very moist -- which I don't do faithfully, being a lazy gardener.

Perhaps the fact that it's 10-15' north of my house and shaded in 
winter helps? That would exaggerate the seasonal swing in 
temperatures, also the diurnal swing in winter.

It might be worth noting that the established patch has the bulbs 
just below soil level. Maybe the original poster planted hers too 
deep in the pots?
