Alexander Palm / Solitaire Palm

Archontophoenix alexandrae

Light Requirement: Full sun to partial shade. Young palms appreciate some protection from harsh afternoon sun, while established palms can handle more direct sunlight.

Height: Typically 25–40 ft. tall in Florida landscapes, with a narrow spread of about 10–15 ft.

Growth Habit: Moderate to fast-growing, single-trunk feather palm with a smooth gray trunk, bright green crownshaft, and graceful arching fronds. It has a clean, elegant, tropical appearance.

Hardiness: USDA Zones 10b–11; cold sensitive and may be damaged by frost or freezing temperatures; moderately drought tolerant once established but looks best with regular irrigation; moderate salt tolerance, though it is best protected from heavy direct salt spray.

Maintenance Info: Low to moderate maintenance. Alexander Palm is naturally self-cleaning, meaning old fronds usually drop on their own, reducing pruning needs. Provide well-drained soil, regular watering during establishment, and palm fertilizer during the growing season. Avoid planting too close to structures or high-traffic areas where falling fronds or fruit clusters may create cleanup.

Best Uses in the Landscape: Excellent as a tropical specimen palm, driveway or entryway accent, pool-area palm, courtyard planting, formal row planting, or vertical accent in tighter spaces. Its smooth trunk and narrow habit make it useful where a clean, upright palm is desired without a wide clumping base.

Plant Info: Alexander Palm is native to northeastern Australia and is valued for its smooth trunk, bright green crownshaft, and refined tropical look. It is often used in South Florida-style landscapes where a tall, clean, elegant palm is desired. Mature palms may produce clusters of small red fruits beneath the crown, adding seasonal color and wildlife interest.
