Min -5°C 23°F
Sally Levinson in an overgrown garden
on the north side of Heinz Ave, between San Pablo Ave and 10th Street in Berkeley California.
Dr Les King comments, 'Shows many features in common with P. subpeltata,
but differs from normal forms in having larger flowers and foliage, more
prominent petiole glands,
purple/blue coloration to corona, and in being more vigorous and
hardier. It appears to be a hybrid of P. subpeltata, or of a related
species, possibly with P. caerulea. Named after the location in
California where it was found in cultivation in 2006.'
