Thank you Jill Ann,

I bought winter pansy plants one fall. They bloomed that fall, grew all winter, bloomed again in spring, then died in the summer heat. Par for the course, I now understand. But the following spring I found several johnny jump up "violunteers" near the spot where the pansies hasd been. I think they might have been come from seeds from the pansies. They disappeared completely after that: Poof!
