Fast grower once the trunk starts to get large. Very good garden plant.

Imposing, very stately, up to 30 m tall (100 ft), with light gray, erect, cylindrical trunk up to 22 m (70 ft). A very fast grower once the trunk starts to get large. With its white marble column-like trunk, superb green crown shaft, and graceful spreading crown of feather shaped leaves, a fully-grown tree is an awe-inspiring sight, and amazing to think that this huge tree grows from such a small seed. Often said to be the most attractive of the Roystoneas, despite not being as commonly grown as some others. A very good garden plant, only the larger garden however. The leaves are in a crown at the top of the stem, 3-5 m long (10-16 ft) with leaflets of about 1 m (3.25 ft) in two horizontal ranks. Leafstalks, of about 1.5 m (5 ft), broaden to surround and sheath stem. The flowers are born in large-stalked panicles revealed when the leaf-sheaths beneath them drop off, with abundant blue-violet fruit are small, obovoid, and without stalks.The fruits are oblong-ellipsoid, blackish at maturity, and about 3/4 in. long, 3/8 in diameter. Roystonea oleraceae has ascending leaves, giving the crown a somewhat flat appearance. Hardiness zones 10-11 (1°C/35°F, 4°C/40°F) in winter. Prefers a sunny, moist position, and doesn't mind wet feet. The plants like a rich soil. Water regularly but do not over water.
