While they can survive colder temperatures and drying out, defoliation is a stress response, not something that routinely happens in nature, and not usually a trigger for flowering.

I try to limit the sources of information an AI accesses and keep it on track by precise phrasing and hard boundaries, but in this case I didn't follow up every link it provided, or try to independently verify all of its claims. > > Steve > >> On 7/15/2026 12:56 PM, Dennis Kramb via pbs wrote: >> Mine never bloom either.
