More California native plant suppliers; search for Wyethia ovata

In my search for Wyethia ovata (Southern Mules Ears), I've found a few more local sources for native plants but alas no Wyethia:

SEA Lab in Redondo Beach was a verbal recommendation at last week's seminar:
"Sea Lab is located on North Harbor Drive, easily accessible by public transportation and on a highly visible corner near the Redondo Beach Harbor."

California Native Plant Link Exchange works. Some of its inventory lists are out out date. It did tell me that Wyethia might have a new name, Agnorhiza ovata, but it appears not to be in widespread use. So much for the supposed stability of the dog Latin names.

Tony Baker over at Natural Landscapes has plants grown from local seed and cuttings.

There's a Native Seed Network that looks promising.
