SRG is having a good sale (up to 80%off) and they have Arizona sun for 2.49, hardy to zone 3 but the Arizona Apricot is 9.99 they are only taking orders for next year.
I just ordered some Coreopsis, painted ferns, Foxglove, and Purple sensation. I was going to order PowWow Berry but I found some seeds on one plant I forgot about.
