Others seek out the rarest plants; Pam Peirce has scouted old gardens to find treasures among historic Bay Area ornamentals, the ones that thrive with little or no care. She found many handsome, drought tolerant, mostly deer and snail resistant plants we can still love in our new sustainable landscapes. Her presentation is partly horticultural history, partly an exploration of plant adaptability, and partly design inspiration for using these old plants, and their newer varieties, in new settings. Her images include maps to show plant origins. (Surprisingly, many are not from mediterranean climates.) $15, $12 members
