trying again with more photos - this plant grows in or around the dunes near monterey bay (i believe it's a native, though who knows).
Plant is about 15" high, likes full sun, very little water, sandy soil.
thank u growin!
i'm pretty sure this is Senecio flaccidus Less. var. douglasii
(and not Senecio flaccidus Less. var. monoensis)
