Leitneria floridana, commonly known as Corkwood, is an unusual deciduous shrub or small tree found only in the southeastern United States. Growing up to 8m tall, the plant has narrow-elliptic to elliptic-lanceolate leaves and produces small flowers in slender greyish catkins in spring. It is dioecious, with male and female flowers borne on separate plants, and thrives in damp habitats, mostly in coastal areas. One of its most remarkable features is its extremely light wood, which has a density less than that of cork, and is used locally for fishnet floats or bottle stoppers. The plant is named after German natural scientist E. F. Leitner and is of conservation concern due to being endemic. Its rare and botanically fascinating qualities make it a must-see for any plant enthusiast.
