Cuban Royal palm

The Roystonea regia (Kunth) O. F. Cook (1900) is native to USA (Florida), Mexico, Belize, Honduras, Cuba, Bahamas and Cayman Islands, where it grows both in the wet forests and in the savannas, in usually swampy areas. It is the national tree of Cuba.

It shows a single stem, smooth, impressing, with a slightly irregular outline, and enlarged at the base, of whitish colour, it reaches a maximum height of about 25 m with a diameter up to 70 cm; the foliar base, smooth and of a glossy pale green colour, wraps up completely the stem for a height of 1,5-2 m, forming a sort of elegant capital.

The leaves are pinnate, long about 4 m. It is one of the most ornamental palms due to its impressiveness and elegance and is one of the most cultivated in the tropical and subtropical countries, where it is often utilized as tree on the sides of avenues and alleys.

The cultivation can be tried also in warm temperate zones, in full sun, as it resists to temperatures just under the zero for short periods, where, however, it shows a less thick crown and a speed of growth much inferior.
