Does anybody grow that plant?
Where can I find seeds please?
Did you have any success finding seed, John ?
I'm interested in it too, but I think the availability of such rare seed is very restricted.
Looks pretty cute! So the 'rosea' flowers are the new ones and they then turn yellow?
I don't know of a seed source, but here's some handsome photographs:
Cohan, according to the last link, the flowers open yellow then age to orange-red.
Sure would like to give this one a whirl.
Our own NARGS Forum member Fringe from Seattle, Washington, might be a good resource in the future. The Fringe Nursery listing has 2 Balsamorhiza species listed, unfortunately not B. rosea (which is found in Washington to Oregon).
