Although this species is hardy to 29 degrees (I left mine outside in 29 and they are still alive), I think they really do depend on the long tropical growing season and I wouldn't recommend these for someone who plans to keep one in the garage over the winter. Even after repotting my seedlings into 5 gal pots, they just don't grow here in north FL. I guess you can grow them next to sabal palms so you can pretend the sabals are growing fast!

My triple T. radiata palms were planted just before a severe freeze (Jan. 07) and survived without any problem. They have been growing steadily and look healthy in the sunny, south facing location.

While vacationing on Floridas southeast coast I was impressed to see T. radiata used much more in landscape design. Here in southwest Florida it is becoming more popular and in my opinion it is the epitome of grace in any landscape where it is given room to spread its crown. Although touted as being very slow growing (even in Florida), I have found that proper watering and a good fertilization program will make a large specimen in just three to five years. Although it will take considerably longer to get significant trunk height. It is not as happy with poor or impoverished soils as the experts lead us to believe. This palm takes an open exposure and wind well. It is at its best with full sun or at least under very open canopy shade. It makes a first rate container specimen when young. Lots of heat? No problem.

Young palms of this species are very attractive, but should really only be grown in humid environments- this palm struggles even in the zone 10a in southern California but does great even in marginal areas of Florida which are colder, but a lot more humid. I have tried with this palm and even though I still have some surviving plants in the ground after 5 years, it is not a good palm for me... it literally seems to shrink every year- stem gets a bit narrower, and leaves much smaller... Oh well. Commonly sold in clumps in nursery outlet stores as indoor palms, but it's not too good for that use, either. Native of Florida and the Caribbean islands. Solitary fan palm with large, nearly circular deeply split leaves that droop after the split. THrinax palms look a lot initially like Coccothrinax palms but the trunk looks very different- this genus has split leaf bases, while Coccothrinax palms do not.
