Kōwhai stands as a winter-deciduous small tree, potentially growing up to 25 feet (7.62 meters) tall. It displays a significant two-stage growth pattern, with a divaricating, bushy juvenile phase, leading to an upright mature form with open branching. The tree is distinguished by its vivid yellow blooms, which appear in late winter to spring within short axillary clusters. Its compound leaves are finely textured. This species is notable for its resilience to low temperatures, surviving down to at least 20°F (-6.67°C).
