Spindle palms and Bottle palms are slow growing and will take at least 10 years from a 7-gallon size to reach 15 feet.

Pindo palms are very slow growing.

Hi
Since they will be in planters with some protection maybe some of the more exotic types such as sealing wax, licualas, or even the silver Joeys?? Maybe some of the rarer types of cycads?? gary

Gary, I'm fascinated by the sealing wax palms, but as I explored on the internet, I found a number of reports of them croaking if the weather gets below 40 degrees. We don't get many nights like that in Palm Beach County, but we do get a few every winter. Have you a better report?

I've been looking at the bottle palm. I like the buccaneer also, but they are apparently very expensive. I'll look at the others, zackey and fawn, thanks, and the other two, gary, thanks.

Red Sealing Wax Palms are a major expense and huge gamble in zone 10. If you can completely shield them from the wind and plant them on the south side of the house, in mostly shade, you've got a shot at keeping them alive.
Licuala's are nice but messy and they have thorns, so if you have little children, by all means, plant them.
There are only a small number of nurseries growing Buccaneer palms because they are so very slow. I bought some for landscape job several years ago at $50 each in a three-gallon can. Not worth the money.

Fawn,

No little children here - my youngest just finished her first year at UF- but my hubbie says no thorns or spines, and I'm with him on that. We have enough battle scars from the darned bougainvillea.

What about dypsis baronii (sugar cane palm)? Anyone have an opinion?
