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.
