ʻŌhelo ʻai is a shrub usually 0.1–1.3 m (3.9 in – 4 ft 3.2 in) tall, rarely up to 2 m (6.6 ft). The leaves are evergreen, spirally arranged, leathery, oval, 1–3 cm (1⁄2–1+1⁄4 in) long, red when freshly emerging, then green or green with reddish patches. The flowers are bell-shaped, 8–12 mm (5⁄16–1⁄2 in) long, variable in color, red to yellow or pink.
Fruit
The fruit is an edible berry 8–14 mm (0.31–0.55 in) diameter, ranging in color from blue to purple to red to orange to yellow. The color does not necessarily indicate the ripeness of the berries. The berries taste somewhat similar to the related cranberries, less ripe ones being tart, while ripe berries are quite sweet but bland. They are an important food source for the nēnē (Branta sandvicensis); the seeds are dispersed in the birds' droppings (endozoochory).
