I have several plants and I failed to collect any of their seeds. Now that spring is here and little seedlings of every weed are popping up, what do the Indian pink seedlings look like?
Sorry I can't help, at first I thought it was Indian Feather which I have, but reread it before I posted, luckily.. Google Indian pink seedlings, images, that should help!
I'd suggest you wait to weed until the little plants get big enough to ID. Once they get their first true leaves (the second set), the leaves should look like miniatures of the parent leaves.
