Not a great shot, but such a pretty color. Solanum -- probably xanti (main one listed as common, & best match). Not parishii (“leaf sessile or gradually tapered to base”). Umbelliferum may be possible -- key indicates that hairy upper stem is diagnostic of umbelliferum, but photos on CalPhotos don't seem to match that at all. Anyway, the Jepson entry says says, ”Variation complex; may hybridize with S. parishii, S. umbelliferum.“
