I was out strolling in one of my garden beds, where I happen to have Thalictrum growing. It is a lovely, delicate plant, and a great one for self sowing. The plant is settings seeds, but the stems are not fully brown and the seeds still look green. However, lots of them were falling to the ground or flying off when I touched the plant.

I grabbed the stem and ran my hand along it, easily coming up with a handful of seeds that were still a little sticky. .Actually, I think these are the seedpods, each of which contains a tiny seed. I broke open a few just to have a look, and the seeds inside still look pale green .Is it safe to gather them now? They practically fell off in my hand. I would like to deadhead the plants or I will have a million seedlings to pull next year.
