weed with black seeds

What’s this spindly weed with sharp seeds?

The plant below has thin black seeds, almost needle-sharp, that are also slightly burred so their sides cling to fabric. Seeds maybe a half-inch long. It grows in medium shade (not deep shade) at forest edges, reaching maybe a foot or two high. It blooms in late spring, goes to seed in July in the Willamette Valley in Oregon. The flowers are small at the end of thin stems, and yellow if I recall correctly. Do you have an idea of what it might be?

After much poking about, I encountered the genus Osmorhiza. I now believe the plant in question is Osmorhiza berteroi (aka O. chilensis), commonly known as mountain sweet-cicely.

It’s possible that it is a different Osmorhiza species, such as O. purpurea or O. brachypoda, but I think it is most likelyO. berteroi. That species has flowers are white or greenish-white, so my vague memory of yellow flowers must have been incorrect.

has anyone ever gotten black seeds? i mean like really black. not grey or dark, but blackish purplish seeds? if so what was your experience with them?

reason i ask is i just ordered a bunch of seeds, and got a bunch of freebies along with it. and there is one strain that i got 2 seeds from as freebies, and the seeds are almost purple/black they are so dark.
