Invasive Species: Cupaniopsis anacardioides, Carrotwood

Carrotwood is an invasive evergreen tree that can grow to a height of 35 ft. (10.7 m). The inner bark is orange; hence the common name. The leaves are compound with 4 to 10 leaflets; each leaflet is 4 to 8 in. (10 to 20 cm) long and shiny with rounded or emarginate (indented) apices. Flowering occurs in the winter when small, greenish white, five-petaled flowers appear in clusters in the leaf axils. Bright orange capsules with shiny black seeds ripen from June to May. Carrotwood is native to Australia and was introduced into the United States as early as 1955. This tree can grow in full sun or shade and has been shown to be salt tolerant. It occurs in marshlands, cypress swamps, pinewoods, and dunes.
