Plant Species of the genus Castanea

Information about this genus
Name: Castanea
Cultivation: CULTIVATION: Sweet chestnuts prefer a well-drained and slightly acid soil; adequate rainfall is essential. Most are frost hardy down to Zones 4 or 5. Propagation is usually from seed which should be sown as soon as it is ripe; selected clones can be reproduced by grafts onto 1- or 2-year-old understocks, in early spring.
Description: Belonging to the Fagaceae, or beech family, this is a small genus of about 12 species of sweet chestnuts native to the temperate regions of the Northern Hemisphere, from North America across Europe and into eastern Asia. In habit they range from low suckering shrubs to tall trees. Several species are of economic importance, being grown for their sweet-tasting edible nuts, which are enclosed in a spiny whorl of bracts. The taller species are also valued as ornamental trees for parks and large gardens, especially for their spectacular yellowish green drooping catkins.
