PlantFiles: South American Foxtail Palm, Sumunqué Palm
Syagrus sancona

Here in the SF Bay Area (Los Altos) 9b, this species of Syagrus does fine. I planted a 10 gallon specimen that was nearly 4 feet tall in a mostly shaded area, which slows growth, but it has still managed a couple feet of growth. It's not fussy but looks its best when kept wel watered.

Great looking Syagrus- probably one of my favorites- called a foxtail palm since it looks vaguely like a Wodyetia (though leaflets or lancelote instead of premorse, and no crownshaft)... but does have relatively wide leaflets in a 360 degree plumose pattern around the petioles, making the leaves look a bit like a foxes tail, I guess. Tall Syagrus (the tallest I think- 80'?) from South America (as all Syagrus but one are). Fast grower. Mine in THousand Oaks (zone 9b) did great (haven't seen it in a few years) but it did get badly frosted one year by unusually cold winds... but with protection this palm should do well in zone 9b. Best in the tropics though.
