Tropical Plant Database - Plant Details

Oahu False Ohelo is a shrub growing up to 5 feet tall. In cultivation, it generally grows about 3 feet tall and can get up to 10 feet in diameter. The young branches are gray, yellow, or reddish brown. The leaves grow with two leaves opposite each other on the branch, overlapping, and are dark green or grayish on the upper surface and lighter green underneath. They are oval to round and usually under 1 inch long. This species is highly variable, with the leaves ranging from large and long to small and round. The stems do not snap but peel when you try to break them. Oahu False Ohelo flowers irregularly throughout the year, but produces fewer flowers when the plant has mature fruit. The tubular yellow to yellow-green flowers are unisexual, either male or female, and less than 1/2 inch long.
