Since no one has responded on the list to this, I looked up our topic of the week in 2003 which was about this. This was my introduction and you can sort by subject to get replies. pbslist/2003-October/vbcgd3h2el59631ouv2l81tpd0.html It seems that buying tender winter growing bulbs at the wrong time of the year when they are sold by some sources may result in flowering that year, but often the next year they either don't come back or revert to the season they prefer. Some bulbs (Boophone disticha is an example) grow in both the summer and winter rainfall parts of South Africa. I tried to turn a summer rainfall one into a winter one and had no success. And the same with a Paramongaia weberbaueri that I thought should grow in summer, but had other ideas. One exception for me has been Brunsvigia grandiflora. It flowers in summer in South Africa, but when it flowers for me it flowers in winter and is dormant in summer. I think we have all had experiences when a bulb flowers at an unusual time (Geissorhiza imbricata this August), but for me that has often been a one time event.
