Silver Buttonwood (Conocarpus erectus var. sericeus)
Location: Kohala Coast, Big Island, Hawaii
A popular ornamental plant here in Hawaii is the Silver Buttonwood (Conocarpus erectus var. sericeus). It thrives in full sun and is known to be both salt-tolerant and drought-tolerant.
Because of its pale silvery-green leaves, this plant often is used in landscaping to provide a contrast to darker foliage. It is sometimes used as a hedge, but in other settings the bushes are planted as individuals. We have about a dozen Silver Buttonwoods, interspersed with Ficus trees, planted along one edge of our property as a sort of natural fence.
The Silver Buttonwood bears tiny, pale flowers that mature into small fruits, which grow in clusters on a stalk. This close-up photo shows the silvery leaves and the mature fruits.
