This is the one Honolulu Botanical Garden that costs to visit . . . only $5 a person. But it is worth every cent. It is small, only 14 acres, and right in the middle of Honolulu next to H1. To truly enjoy and have time to photograph the wonderful plants, give yourself about two hours. There is a visitors' center, restrooms, water, gift shop and picnic tables on site.
Many of the trees were planted as early as 1850 in what was then a private estate. 26 trees in Foster Gardens have the designation "Exceptional Tree". There are only 100 such trees on the island of Oahu. Near the entrance is a colorful display of Crotons and Bromeliads. Nearby is the Lyon Orchid Garden and an orchid house for more modern hybrids. The Prehistoric Glen features plants that have survived from primitive times, a humbling experience. Be sure to find the CannonBall Tree and the Sausage Tree . . . both close together.
Bring a picnic lunch and watch the birds that populate the park.
