Apart from the leaf Sabal palmetto leaf anatomy, palms are widely different in growth habit as well. Some species are suckering (forming multiple stems) like the European fan palm, the lady palm (Raphis excelsa) or the dwarf sugar palm (Arenga engleri) the date palm (Phoenix dactilifera) can do it at a young age before forming a trunk, but does not do that in all occasions. Suckering date palm Arenga engleri Raphis excelsa Other species grow solitary (with single trunk), like the Washingtonias, King palms (Archontophoenix sp.) or the windmill palm (Trachycarpus fortunei). Apart from suckering and solitary palms, there are also climbing palms, most notably the rattans, which form long slender shoots that twist as lianas around stems and branches of other trees, most climber palms are also suckering and form new branches from the ground. Plectocomia himalayana (rattan palm) Another unusual growth habit in palms, although very rare, is branching. It occurs in only a handful of species, some of which are the climbing rattans but most notably the Doum palm (Hyphaene thebaica) from Northeast Africa. All palm species mentioned in this article (except the coconut palm) can be grown here at the Costa Blanca! In the next article I will discuss some more interesting aspects of palms and introduce some more fascinating palm species suitable for the Costa Blanca gardens.
