Fwd: Ferraria crispa Corms

In my experience, when you have a bulb that never flowers but just 
splits up, the best thing to do is leave it alone for a few years 
rather than repotting constantly.

Flowering is sometimes thought to be a response to a "threat" to the 
parent plant's continued existence, and depletion of soil nutrients 
may be a trigger. In contrast, splitting up can be a response to 
predation by digging animals -- the more tiny corms are present, the 
more chance the plant can survive disturbance. I don't know about 
Ferraria in particular, but South African bulbs are quite subject to 
being dug up and eaten, e.g. by baboons.
