I have a fairly good size area that I want to put the purple dragon in. All the plants at the local nurseries recommend planting about 12" apart. I would need about 100 + plants and can't afford that. Are you aware of any seed source for these that I could start this winter/spring and then transfer to where I want them? I've "googled" and can't locate anything.
Ewarchery, you should also probably try to contact Dan Brown, who has planted hundreds (!) of these plants. He has responded on Dave's Garden on this entry. As Carrie Lamont already noted, seeds don't do the job on this plant. Cuttings or division are probably the ways to go.
