George, do you grow Nerine bowdenii and N. sarniensis? And if so, do they bloom regularly for you? Both grow well in a cold frame for me here in zone 7a Maryland, but they are very erratic about blooming. Nerine sarniensis has been outside in that cold frame 24/7/365 since 2005. It has bloomed three times during that period. Amaryllis belladonna has been in the same frame for just as long and has become a corpulent space hog - and has yet to bloom even once.
