Species and varieties

Chamaerops excelsa: originally from China, it is usually classified as Trachycarpus fortunei. It reaches 12 m. in height and is suitable for cultivation in open ground.

Chamaerops humilis: also called Palma di San Pietro, this dwarf palm (does not exceed 2 m in height), grows spontaneously also in Italy, reaching a maximum of 1 m. in height and width. The stems, sometimes branched at the base, carry, at the apex, a tuft of leaves with a long, thorny petiole, with a woody consistency and, often, with a biconvex section. The foil (up to 45 cm wide) is webbed and divided into linear segments that give it the appearance of a fan. The panicle-shaped inflorescences are formed at the base of the leaves and are followed by elliptical and red or yellow fruits. It can also be grown in pots, as a houseplant (they are usually young specimens), which can be taken outside in the warmer months. The variety "Dactylocarpa" reaches 6 m. in height.
