I often go to Oregon and northern California in the spring, photographing wildflowers, and sometimes collecting seeds. I have seen only two species of calochortus, as they flower later than I usually go. I've been reading Mary Gerritsen's calochortus book and find that some of the species produce bulbils. It would be exciting to find a particularly pleasing flower and be able to collect a bulbil from it. However, the book does not give precise information about this. When are bulbils developed enough to be viable? Diane Whitehead
