Does anyone know where you can either buy seeds or plants (in the Bay Area) for Indian Paintbrush (Castilleja affinis).
Hi -- Did you ever find these? I see that Seedville has the seeds for sale on Amazon.com.
I don't know where to find seed, but I did want to mention that I believe the plant is partially parasitic to tree roots (oak, I think)...so, I have to wonder how easily they can be grown from seed or successfully grown to maturity without this host. Just a thought.
Good luck in your endeavor, and if you find more information or achieve success, please post a follow-up.
I think you might be thinking of the "Indian Pipe" plant(Monotropa uniflora) which is myco-heterotroph, that is, it is parasitic to the fungi that live on tree roots.
Don't know about that species but the Castilleja we have in the east is a hemiparasite of grasses. Squaw root is a parasite of oaks.
Native American Seed should have Indian Paintbrush seeds.
