Dear Dave and Lauw, Each year, I have brought my spring blooming Iridaceae into the greenhouse in September or October. I have Anomatheca, Lachenalia, Moreae and Lapeirousia. The bulbs bloom well, but the stems are weak, causing the inflorescences to topple. Lachenalia. Could the relatively low light be the cause of the floppiness? If yes, perhaps I could delay the growth onset till mid-February. I had not thought Lachenalia to be frost hardy in our USDA 9A. However, this spring I found a single L. viridiflora blooming in my rock garden. Most amazing.
