Rhodophiala bifida

I can't grow Rhodophiala bifida here in northwestern Oregon, either. The 
plants just dwindle away over several years, as so many plants from 
summer-damp, hot climates do. I agree with Mary Sue that cold nights are 
probably the culprit. A 35-degree F (about 24 degrees C) difference between 
daytime and nighttime temperatures in midsummer is common where I live. The 
drop is a function of low atmospheric humidity, proximity to the cold 
Pacific coastal waters, and elevation gradients.

Amaryllis belladonna will grow here but not flower (it will flower in the 
city of Portland, where the heat island effect raises night temperatures), 
and Nerines are greenhouse subjects exclusively. However, I can grow 
Zephyranthes and Habranthus in pots and flower them pretty well in summer.

So, southerners and easterners, enjoy your subtropical amaryllids, and we 
will enjoy our Mediterranean and Californian bulbs!
