I'd like to try a Crinum in my new, warmer garden, but need to know if there are any kinds that can flower without a high summer heat and humidity. I have a damp corner near a water feature that might suit one, and the water would raise the humidity locally, but our "heat waves" typically last about three days, and summer night temperatures typically drop into the 50s F. Any recommendations from other cool-summer areas? Jane McGary Portland, Oregon, USA
