Thanks to an abundant average rainfall of 165 inches, the Lyon Arboretum offers a tropical rainforest setting that is ideal for growing an enormous diversity of plants, which is one of the reasons the grounds often serve as an outdoor laboratory for local students. The Lyon Arboretum opened to the public in 1972 and it's collection now features heliconias, gingers, aroids, bromeliads, native Hawaiian plants, and one of the largest palm collections found in a botanical garden.
