1. Soak the corms (or are they tubers?) in water for 48 hours. Fresh water 
after the first 24 hours. Then plant.

2. Plant in the shade on the north side of your house: that's usually the 
coolest part of any garden. E. hyemalis is very hardy, coming as it does from 
cold-winter places.

3. When they flower, exaine them closely; you may very well have E. cilicia, 
not E. hyemalis. E. cilicia does better in dry summers, and has a greater need 
for lime in the soil.
