This garden is a living treasure box of native Hawaiian coastal species and plants brought here by Polynesian voyagers in their seafaring canoes. Stroll beneath the shade of the hala and breadfruit trees. Learn how the first Hawaiians made everything from medicine to musical instruments out of the plants they found growing in these islands. Ask to see the hapai (pregnant) banana tree—a variety with fruits that grow inside the trunk! Take a self-guided audio tour or take a do docent-led tour ($10) Tuesday through Thursday at 10am. If the garden happens to be hosting a lei-making or kapa-dyeing workshop while you’re on the island, don’t miss it.
