The Story

Plant Bio

Sabal mexicana, or Mexican Palmetto, is a slow-growing, evergreen fan palm. It features large, costapalmate fronds and eventually develops a stout, solitary trunk. It produces long, arching inflorescences of small, creamy-white flowers followed by black, pea-sized fruit. Selected for its superior cold hardiness, 'Dallas Form' is a robust cultivar capable of withstanding colder temperatures than the typical species, making it a reliable choice for gardens in USDA Zone 7.
