Common Names Betel Nut Palm, Areca Palm, Pinang Palm, Indian Nut
 
Zones 10A–12
 
A slender, fast-growing palm native to Southeast Asia and widely cultivated for its seed—the areca nut—used in traditional betel chewing. Its smooth, ringed trunk and compact crownshaft give it a classic tropical silhouette. Though primarily grown for agricultural use, it also serves as an elegant ornamental in warm climates and large indoor spaces.
