Yes - you can grow most of them from seed @steph_val , but by the time they're a decent size for planting out, your original plant will probably be big enough to divide, so it depends on whether you feel it's worthwhile I think some of them will self seed too, but that might depend on your location and the general conditions.

Not something I've ever done @punkdoc, and it's a long time since I had that one, but I'll bow to your better knowledge of them! They grow fairly rapidly so I've always divided anyway, rather than relying on seed sowing and growing.

I don't know about Hewitt's Double, but I grow thalictrum delavayi and get lots of seedlings in the area the following year that I move to other parts of the garden.

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.

It lacks the working parts needed to produce seed.
Hence expensive price tag to buy them.
One of my favourite Thalictrums.
