A Tomatillo Flower Bud

I think.
Tomatillos are husk tomatoes, and we love to eat them in salsa verde.  When the first little puff of green appeared on a tiny stem in the crevice where the leaves branch off from the stalk of this aggressive plant, I thought it must be what some gardeners call a "lantern" but chances are it is a flower bud instead. 

Well, I have never grown one of these before, but it is going to be a challenge for me to play honeybee with it indoors, because, for one thing, people commenting on the process online are divided as to how self-pollinating it is.  Some say all it needs is a vigorous shake and others say you need more than one plant to get any fruit. 

When I figure it out, I will post my findings on my other blog:
