I am pleased for your success Mary Sue and have no certain explanation. I
sure that you already know most of this but some readers may not.
I find that, typically, corms will not regenerate for the following year if
they enter dormancy too soon.
This happens very easily in pots or on raised benches, where temperatures
in the compost may rise or fluctuate wildly in the Spring, and also where
premature dormancy may occur due to pots drying out between watering. When
corms and certain bulbs, (especially those without perennial or Summer
roots), go dormant for a Summer rest, the dieing leaves and roots and
tunics are very prone to infections in wet or humid conditions such as a
late watering, given to try to prolong the growth period, especially in
warm weather.
 Strong shoot growth, when corms break dormancy, may require plenty of
water if the shoots are to achieve flowering that season.
