I have the poorly-growing, non-flowering strain. I got some mixed-flower-color bulbs at a big box merchant and grew them outdoors in an 18" wide pot for a few years in morning sun. They lived and grew larger somewhat, and offset. Then I read this species/hybrid does better as a pond marginal in the sun, so in April I set the pot in my pond in full sun. The water level is well below the basal plates but the soil is always wet. The bigger leaves disappeared during our record-hot July but there are four smaller leaves, looking extremely healthy, that have remained looking exactly the same, not growing at all, for at least the last 12 months. I can't really be sure what it is because it never blooms. Leo Martin Phoenix Arizona USA
