Purple King Palm Identifying Characteristics
Its single, smooth gray trunk, slightly swollen at the base and approximately 1 foot in diameter, is prominently marked with the scars left by shed fronds.
It takes several years for this palm to develop the distinctive reddish-purple crownshaft that creates a striking contrast against its dark green leaves.
Atop the crownshaft, you’ll find stiff pinnate fronds, resembling feathers, ranging from dark green at the top to a shiny silver on the underside.
These fronds measure approximately 7-12 feet in length, with 50-60 flat leaflets each spanning 13-14 inches.
Purple King Palm Flowers and Fruits
The Purple King Palm produces clusters of white-creamy flowers, supported by 2-foot long inflorescences that emerge from where the crownshaft meets the trunk.
These flowers are followed by berry-like fruits that turn red when they ripen. These fruits are around 1/5 inch long and contain a single seed.
How To Care For Purple King Palm
In terms of cold tolerance, the Purple King Palm can withstand temperatures as low as 25°F for a brief period, provided it has reached maturity. It thrives in USDA Zones 9b (25 to 30°F) to 11 (above 40°F). This palm prefers partial shade or full sun exposure and thrives in moist yet well-drained soil.
The Purple King Palm demands minimal maintenance, as it features a self-cleaning trunk. To prevent nutritional deficiencies, it’s advisable to use a high-quality palm fertilizer with a continuous-release formula, applied twice a year during the growing season.
Propagation is typically achieved through seeds. Seed germination is a straightforward and speedy process, occurring within 6 weeks to 3 months. It’s best to sow the seeds fresh in the spring for optimal results.
