Inventory Numbers: 537

The Hinoki falsecypress (Chamaecyparis obtusa) is native to Japan. It is an evergreen conifer that grows up to 120′ tall in its native habitat. It has a pyramidal shape and features spreading branches with flattened horizontal branches that droop at the ends. One of the most attractive features is the dark green whirled foliage. Leaves are scale-like with blunt tips, green in color with white X-like lines on underside. Reddish brown bark will peel on mature trees. A smaller variety of this tree is often used as a bonsai tree due to its slow growth.Introduced to the West in 1961.The cultivated forms include some with dwarf habit. In the ‘Crippsii” cultivar bright yellow coloration of the leaves appears only on the outermost branches. The genus name comes from the Greek chamai meaning “dwarf” or “to the ground” and kyparissos meaning “cypress tree”. The specific epithet, obtusa, means rounded in reference to its leaves being blunt/rounded at the tips. In Japan hinoki means “fir tree”
