Palms and cycads
These feather palms are mostly large trees, though the following list includes one dwarf. Trunks are patterned with bases of old leaf stalks. Small yellowish flowers appear in large, hanging sprays. On female trees, blossoms are followed by clusters of dates—but only if the tree has been in the ground for at least several years and if a male tree is nearby.
Dates of Phoenix dactylifera and Phoenix sylvestris are the ones found in produce markets; those of other species don’t have as much edible flesh. Date palms hybridize freely, so buy these trees from a reliable nursery that knows the seed or plant source.
Canary Island native. Hardy to 20°F/–7°C; slow to develop new head of foliage after damage from hard frosts. Big, heavy-trunked plant to 60 ft. tall, with a great many bright green to deep green, gracefully arching fronds that form a crown to 50 ft. wide. Grows slowly until it forms a trunk, then speeds up a little. Young plants do well in pots for many years, looking something like pineapples. Best planted in parks, along wide streets, or in other large spaces; not for small city lots. Takes seacoast conditions.
