Comments and Curiosities

"This thin trunked solitary palm from New Guinea has a surprising amount of cold tolerance (for a New Guinea palm) and has been grown successfully by many southern California palm nuts in zones 9b and 10a. It has very jagged leaflets - almost fishtail-like (hence the name - caryotoides; 'like a Caryota, or fishtail palm'). The terminal leaflets are particularly fishtail like. It has a rather sparse crown, but is an attractive plant in a smaller landscape." (Geeoff Stein)

A slender, moderately-sized, solitary species from montane rainforest in New Guinea with broad, wedge-shaped leaflets. Rare in cultivation. (
