If you are looking for a single fruit tree or a entire edible landscape, you may find what you need at one of the periodic plant sales being held on the grounds of the Bay Natives Nursery at 10 Cargo Way in San Francisco. There will be one April 22 and again on May 13. On both days, at 1 p.m., there will be a talk on Edible Backyard Gardens by Mike Boss, Plant Ecologist and Garden Maker.
Available at the edible perennials sales will be trees, shrubs, vines, and non-woody perennials--everything from artichoke plants to unusual citrus.
While you're there, check out the natives at Bay Natives, as well as their lively flock of chickens. Penned next to the nursery is a small herd of goats, also fun to watch.
