Appearance

The Tetraclinis tree has a characteristic blue-green color due to its needle-like leaves that grow in clusters of four. The leaves are about 1 cm long and are arranged spirally around the stems. The tree’s bark is thin, scaly, and reddish-brown in color. Tetraclinis trees produce small, round cones that are about 1 cm in diameter. The cones are green when young and turn brown when mature. The tree’s resin, which is highly valued, is found in pockets beneath its bark.

Care Guide
