This is one of the two most common Ptychospermas in cultivation, from N Australia and New Guinea. It is a tall, spreading clumping species with premorse leaflets and thin, grey, barely ringed trunks. It is found throughout the tropical world being used in malls, parking lots, indoors and in many gardens. It is fast growing and the fruits are bright red making it useful as an ornamental. Here in southern California it is a marginal palm, but does succeed in zone 10a... just slow as molassas. I have seen clumps that looked great, though, along the coast.

Regional...

This plant has been said to grow in the following regions:

Huntington Beach, California
Bonnie Lock-woodsetter North, Florida
Cape Coral, Florida
Fort Myers, Florida
Jensen Beach, Florida
