Purple King Palm Tree Info

Scientific name: Archontophoenix purpurea

Common names: The Purple King Palm is also known as Mount Lewis King, Purple Piccabean Palm, and Purple Palm.

Family: Arecaceae

Origin: It is native to Australia.

Appearance: It has a single smooth gray trunk, a little swollen at the base, about 1ft in diameter, prominently ringed with the scars of shed fronds. It takes several years for the palm to develop a stunning reddish purple crownshaft that makes a striking contrast against the dark green leaves.

Crownshaft is topped with stiff pinnate, or feather-like fronds that range from dark green to light green on the top and shiny silver on the bottom. They are about 7-12ft long, with 50-60 flat leaflets that are 13-14 inches long.

Flowers/Fruits: The Purple King Palm produces white-creamy flowers that hang in clusters. Flowers are supported by 2ft long inflorescence that grows from where crownshaft meets the trunk. Flowers are followed by berry-like fruits that turn red when ripe. They are 1/5 inch long, with a single seed inside.

Growth Rate: Slow. Archontophoenix purpurea is a fast-growing palm that can grow up to 10-20 ft tall with a spread of about 1-5 ft.

Outdoor/Indoor Use: Both.

Cold Tolerance: The Purple King Palm can tolerate cold down to 25F for a short period of time when mature enough. Grows best in USDA Zones 9b (25 to 30 F) to 11 (above 40 F).

Light Req: Partial shade to Full sun.

Water Req: Moderate. It grows best in moist but well-drained soil.

Maintenance: Easy. This palm requires very little maintenance since it has a self-cleaning trunk. To prevent nutritional deficiency, apply good quality palm fertilizer that has continuous release formula twice a year during the growing season.

Propagation: Propagated by seeds. Seed germination is quick and easy. Germination occurs in 6 weeks to 3 months. It is best to sow seeds fresh in the spring.
