The endangered native Royal Palm is a large, relatively fast growing palm that under good conditions can grow approximately 1 foot per year, with the potential of ultimately reaching 75 + feet.

The stem (trunk) is a grayish-white color, slightly thickened at the upper portion of the bole.
Several ranks of pinnate leaves grow from the frond stems at various angles giving them a "feathery" appearance.

Royal Palm has fragrant flowers, produced from January through July on inflorescences 3 feet in length, fruit is a purple to black drupe, 1/2 inch long.

U.S.D.A. Zones - 10, 11. Grows best on rich, slightly alkaline (7.5 or less) to acidic, moist, well drained loamy or sandy soils with full sun to a lightly shaded exposure.

This regal palm is tolerant of windblown salt spray near the coast & has a moderate drought tolerance once established. Propagation is by seed.

Landscape Uses - Specimen tree, buffer zones, Royal palm should not be planted close to houses/structures, footpaths or other locations where the large fronds pose a danger when they fall.
