Hawai'i hawthorn is a slow-growing, ornamental shrub or small tree native to Hawaii and parts of the Pacific, bearing clusters of small white flowers and tiny dark fruits attractive to birds. It prefers well-drained soils and a warm, frost-free climate with moderate moisture. This rare collector's plant requires patience but rewards with a graceful, finely textured form and year-round interest.
