Coastal astelia is an evergreen perennial with a striking appearance, characterized by its silvery or pale-green foliage. The narrow leaves are gently recurved, contributing to the plant's aesthetic. Observers will notice that it typically reaches a mature height of 3 to 4 feet (90 to 120 cm). Coastal astelia displays a dioecious flowering system, meaning male and female flowers are on separate plants, although these flowers are modestly nestled within the foliage and not particularly conspicuous. The plant is adapted to a range of light conditions, from full sun to light shade, and is capable of withstanding brief cold spells down to 20-25°F (-6 to -4°C).
