Royal Palm

Royal Palm

Roystonea or Royal Palm is a genus of 10-12 species of palms, native to tropical regions of Florida, the Caribbean and the adjacent coasts of Central and South America.

They are single-stemmed trees with a trunk which may be thickened either at the base or the central portion, depending on the species.

While walking the Mastic Trail, look for stands of this magnificent tree.

Roystonea regia

This magnificent palm is familiar as a landscape tree in western Grand Cayman, but it grows wild in undisturbed woodlands in Grand Cayman’s eastern districts.

There it rises high above the woodland canopy, growing to about 80ft tall. Traditionally in Cayman this tree has also been known as the ‘Cabbage Palm.’

The upper half of the trunk is lightly banded with scars left by the falling leaves: lower down the outer surface of the trunk is lost, to reveal the densely packed vertical fibres beneath.

The diameter of the trunk varies with height, the growing tip of the palm possibly producing a thicker trunk during years with heavy rainfall, and a thinner one in times of drought.

The smooth green sheaths of the huge leaves encase the top. In the wild, Royal Palm trunks are covered with lichens of all kinds, typically pale greens and greys, with liberal patches of pinkish orange.

The ground beneath the tree is usually a tangled mass of fallen leaves, and when the tree has ripe fruit, it becomes carpeted with the bright red berries. The seeds sprout readily if fresh.

In Grand Cayman, this palm grows in seasonally flooded woodlands and thickets, doing best where there is plenty of fresh water just below the ground surface: for this reason it is often found close to the edges of Buttonwood wetlands.

Royal Palms are also native to Cuba and Florida, where they may grow at higher elevations.

When Royal Palms die, the trunk remains standing for several years, and rots from the core outward.

This makes excellent nesting opportunities for woodpeckers, which bore holes in the sides, and parrots which enlarge a cavity down from the broken top.

Sadly such conspicuous dead palm trunks are easy targets for irresponsible nest robbers, who hack down the whole trunk in the hope of recovering live parrot chicks, to sell illegally as pets.
