Plant Species of the genus Carya

Information about this genus
Name: Carya
Cultivation: CULTIVATION: Seedlings develop a long tap root very early and need to be planted when young into deep, fertile, humus-rich but well-drained soil. The seed should be sown into a seed bed as soon as it is ripe. If growing a species in a pot, use one that is extra deep. Use good loam with added leafmold; cultivars needed to be grafted in winter.
Description: This genus consists of about 25 species of which the majority come from eastern North America and 3 or 4 from Vietnam and China. These large deciduous trees have male and female flowers on the same tree. The gray to brown bark becomes scaly with age. The serrated-edged leaves are pinnate or alternate with 3 terminal leaflets. The male inflorescence is a pendent branched catkin. The female inflorescence appears on a terminal spike with up to 20 individual flowers. The fruit is a drupe; the outer skin comes away in 4 segments, which are occasionally winged. Commercially the genus is valuable for the nuts such as pecans contained in the inner part of the fruit. Hickory wood is a hard wood, used for tools and sports equipment. They resent disturbance and are difficult to transplant. Most hickories are valued for their ornamental qualities as they make majestic trees and the foliage colors well in autumn.
