Chamaecyparis obtusa
Overview
The Hinoki Cypress is a slow-growing evergreen conifer native to Japan and one of the most highly regarded ornamental conifers in cultivation. Known for its dense foliage, graceful branching, and rich green color, it has been prized for centuries in gardens, temple landscapes, and arboretums.
