WIth any luck, you'll eventually see the seed capsules split
revealing clusters of the black shiny seeds, but sometimes the seed
set is rather poor, and you have to locate the seed among the black
debris. Possibly your seeds are ready, since I've just harvested some
of mine despite the stalks still being green and turgid. I seemed to
get a good seed set this year, so I could clearly see the seed when
the capsules ruptured.
