Cultivation

Ptychosperma elegans is cultivated as an ornamental tree for planting in temperate climate gardens and parks.[5] It is a single trunked tree, that in cultivation can reach 20–40 feet (6.1–12.2 m) in height.[4]

The trunk is 1–4 inches (2.5–10.2 cm) in diameter. It is light gray or almost white, with dark leaf base scars encircling the trunk.[6]

The pinnately compound leaves or fronds can reach lengths of 6–8 feet (1.8–2.4 m) and are attached to a 1 foot (0.30 m) long petiole. They are dark green on the top and gray-green on the underside.[6]

Inflorescences produce white male and female flowers. Fruits are bright red, about one inch in diameter, and egg shaped.[4][6]
