A white Victorian glasshouse in Golden Gate Park, modeled on Kew Gardens' Palm House and built in 1879. It survives as the oldest of its kind in the American west, restored after a 1995 windstorm threatened to bring it down. Inside, five gallery rooms cover lowland tropics, highland tropics, aquatic plants, potted plants, and a rotating special exhibit.
The orchid collection alone is worth a visit, and the carnivorous-plant gallery is a small wonder. Closed Mondays; modest admission. Combine with the Japanese Tea Garden and the SF Botanical Garden for a full Golden Gate Park afternoon.
