Spiral leaves of Pandanus

Pandanus is an easy-to-grow tropical foliage plant with sharp, spear-like leaves. It typically grows to about 3 feet tall.

As Pandanus matures, it develops a wood trunk with a thatch prickly-edged, dark green leaves. The edges of the leaves are so sharp they can cut human hands.

With age, Pandanus’ trunk sprouts thick, stiltlike aerial roots that apparently help to prop it up. They extend outward and downward to the soil.

Pandanus’ spiral leaves give it the common name screw plant.
