A tall, evergreen coniferous tree, the Hinoki cypress hails from southern Japan. The soaring tree is often used for privacy screens because it's so tall and dense. It is also a favorite for ornamental plantings, and dwarf forms of this tree are popular for bonsai. Hinoki cypress trees feature globose cones that are 8 to 12 millimeters in diameter. Although dwarf cultivars exist that are just a couple of feet tall, Hinoki cypress species can grow to 75 feet tall, although the more common tree varieties are 25 to 40 feet tall.This tree has a slow to medium growth rate and can grow about 12 inches per year (some cultivars grow much more slowly). It is typically planted in fall or early spring and can be grown from seed sown in spring.
