Palmbob mentioned getting 15-25 years out of this palm before it dies. In South Florida it must progress much faster- I bought mine in 1996 and it is coming down this week (2005). It is a lovely palm- I just wished they lasted longer.

Sort of a marginal palm in Southern California- much better in the tropics where it is commonly used as an avenue palm. Since monocarpic, care must be taken where it's planted, since in 15-25 years it will have to be removed. The wood of this and all Caryotas is extremely hard, making cutting it, even with a chain saw, a challenge. Fast growing tree.
