This has become an issue:

Those little Baptisia seeds disperse EVERYWHERE in my garden in winter and by mid-spring, they emerge and while they’re a pain in the ass to yank out with their taproot, they’re also spindly, weak and nothing like what the beautiful mother plant looks like.
I planned to remove all of the spent blooms in summer, didn’t do it, and then planned the same in the fall and again, didn’t do it.

So we will suffer in spring yet again. I’ll be sure to show you the seedlings/growth to back my argument with corresponding curses thrown in.
My two or three established baptisia plants have never produced babies. I’m a bit envious.
They’re beautiful even as they multiply, but I get what you mean. Love the seedheads, too.
I’m sure the birds would send you thank you notes if they could. they will repay you by eating pesky insects next season.
