Foster Botanical Garden opens its gates tomorrow for an evening celebration of community and outdoor beauty with Midsummer Night’s Gleam, its annual free event.

The garden, a green oasis in urban Honolulu that is listed on the National Register of Historic Places, will be turned into a “magical wonderland,” organizers promise, with special offerings for children and live music for adults.

From 4:30 to 6:30 p.m., attractions for kids predominate, with games, magic, arts and crafts, bubbles, balloon-making and interactive demonstrations by martial artists of the Golden Horde.

As the sun sets, the sounds of singer Skylark, jazz from the Chris Yeh Quartet and harp music will drift over the park, and 2,500 luminaries will glow along the garden paths, lighting the way for an Enchanted Forest Walk. “The ambience!” exclaims Foster Garden recreation specialist Joyce Spoehr.

Perennial attractions include the Wishing Tree, a collection of child-pleasing “critters” formed from natural materials and, of course, the garden’s extensive collection of flowering plants and historic trees. Wear mosquito repellent, and bring a blanket to sit on while enjoying performances.
