The real test will be in whether you develop real pods, and if the resulting seeds will germinate. I have a seed-grown white that my mother's neighbor grew back when hers was the only brug for miles around. The mother---and presumably father---plant was yellow, but all the seedlings were white.

It has proven to be a very hardy plant, and it occassionally sets seeds---but then, I have a yard full of other brugs to be pollen donors!

Well, if there are going to be any pods now, it's only going to be one. I was trying to cut off the calyx from one of the stems (Aphids were hiding inside, the little buggers!), and the stem just snapped right off. I'm leaving the other one alone. I would assume that the plant had to be able to fertilize itself at some point, given the fact that the species made it into our century, so I'm keeping my fingers crossed.
