TIP: Guided tours are available, but reservations are recommended.

TIP: Every year, the conservatory has at least one Corpse Plant that blooms and stinks up the entire place! The plant opens for only about 48 hours, so if you’re lucky, you might get to see (and smell!) it.

Of all the botanical gardens in Honolulu, Foster is the oldest. Some of the largest trees on the grounds were planted in the mid 1800’s.

Although, the gigantic trees are a special feature of the gardens, don’t miss out on other unique plants. The Pitcher Plant, Orchids, Cannonball tree, and Sausage Tree are incredible things to see.
