Lycoris squamigera in warm climates

Some years ago I bought several species of Lycoris, including L. 
squamigera, and they mostly survived winters in the foothills about 
Portland, Oregon, but none of them ever flowered. I assumed this was 
due to their experiencing cool nights and low humidity in summer. 
These conditions often adversely affect plants that have evolved in 
humid-summer regions where night temperatures are not extremely lower 
than day temperatures in summer. A typical example was the past few 
days, with daytime highs around 90 degrees F and nighttime lows 
around 60 degrees F. At slightly higher elevations the drop can be 
even greater.

I never managed to flower Nerine except in a solarium, but I know of 
plants that flower in Portland in the open, especially in sites 
against a west-facing wall. Now I have Amaryllis belladonna in that 
type of site and will see if it ever flowers; it did survive our 
unusually cold spells this past winter. Agapanthus in the same site 
froze to death, but to my amazement Iris unguicularis is thriving 
with almost no damage there.
