Sawara cypress is an evergreen tree native to Japan and grown in American gardens. Its many garden forms vary greatly in size and foliage, including small plants with yellow leaves and forms with slender, drooping shoots.
On typical foliage, Sawara has sharper leaf tips and broader white marks beneath the sprays. Cultivars can change these features, so check several branchlets and any cones.
