What should I do with these seed pods?

I think they’re from wild Angellica. Do I just chuck them into soil now, or do I have to faff with seed trays etc?

And should I open the pods?

This is unlikely to be Giant Hogweed, OP was uninjured collecting it. Umbellifers don’t take up much space as individual plants, and all the white flowered ones are pretty.

Don’t think those look like Hemlock seeds, though it would be good to have a better photo
