something def. in the Coccothrinax family for sure. maybe argentata leaves look too thin to be a Miraguama (my first guess). palms native to Cuba Florida, and The Bahamas. Just my guess -Justin in VB

Im pretty sure its Acoelorrhaphe wrightii AKA Everglades Palm. Its native to florida and grows very tall. Its a clumping palm. Typically in mature clumps there are a few very large plants in the clump followed by much smaller plants. It can also be grown as a single plant by cutting the babies off. Its native to southern florida.

Good luck!

I agree w you Tropicalzone that flew past my mind usually thinking of them in clumps not singles... good eye!

tropicalzone7 nailed it. :) Some of the ones around here had some minor cold damage, but not too bad.

Acoelorrhaphe wrightii don't seem so common to come by. Anyone grow one of these as an outdoor/indoor containerized specimen. All I know about them is that they like a lot of water (even tolerating standing water), take decent sun, survive lighter frosts and temps down to about 20F.--Also seem freely suckering.--I think they're gorgeous by the way!

Ive seen some pretty decent sized and priced ones on ebay sold as an everglades palm. They are very nice palms and common in florida but not so much elsewhere. They grow pretty fast in its native range and can handle neglect and anything florida winters can throw at them including an occasional historical freeze.
I think the thing I like most about it is the leaves. They look very compact and are divided well. This palm might be one to test outside in colder climates with protection.

Good luck!

They have some planted around here in the road medians and they seem to do quite well, even in dry weather, so they will tolerate dry soils as well, even though in their natural habitat, they prefer moist soil.

Tropicalzone, I recently bought one from the eBay seller you were referring to. Boy, is it big and gorgeous!! In late autumn, I'll eventually have to decide to overwinter with the hardier subtropicals or the strictly tropicals.--From what I read, they seem to be able to take some winter chill.

I do not usually see this one.

I never see it locally! When I was in the Keys, I had the choice of driving back with either a Bismarkia or the Everglades palm (can't begin to spell the Latin name for this one). I chose the Bismarkia--which is still going strong but felt compelled to get the Everglades palm one day--I love the Everglades!. Again, the one on advertised on eBay really is BIG and HEALTHY.
