The 'Ilima plant is a spreading or shrub-like member of the Hibiscus family. The flowers are yellow to orange, 5-petaled, and tubular, approximately 1 inch in diameter. Flowers generally open by noon and each last about 1 day. The leaves are 2-3 inches in length, oval, with a pointed end and teeth along the edges. The fruits are brown to black capsules with brown to black seeds inside.
Leis (garlands of flowers) are traditionally made from 'Ilima flowers. This plant is indigenous to Hawaii and is the state flower of the island of Oahu. 'Ilima plants are also important to pollinators, such as the yellow-faced bee, and the flower buds are a critical food source of the endangered Nihoa finch, a species of Honeycreeper. 'Ilima flowers are edible and have been used as a garnish and also for medicinal purposes.
