I grew Dichelostemma species for some years with winter temperatures
fluctuating to a minimum of around minus ten C. my method was to plant the
corms deep in pots of sandy compost topped with gravel. The pots were
plunged in sand with overhead rain protection. They would have frozen solid
on occasion but survived until a winter with lows of ~ minus 15 C. the
trick was to keep them dry until early spring so that they did not freeze
much while in growth. extra feeding was required to compensate for the
shortened growing season.
 My sister also grew "Fire Cracker" in a very well drained bed for three
years in a rather colder winter micro climate with dry summers. It died out
with her after a wet Summer followed by the same cold winter.
