Great tree for SoCal, but I have to correct the previous post. There has been a few that have flowered and died in just my city, Huntington Beach, let alone the state.

Whats great about this tree in Southern California is that Southern California does nothave a tropical climate, so it is slower growing so you can enjoy it longer.

Its a great palm to have though. They probably have the full potential of getting to their maximum height.

In the wild this palm can reach a height of over 100 feet, and the trunk can be 3-4' in diameter. It doesn't seem like it's gonna be that huge in So Cal, as newly trunking palms with about 10-15' of trunk are only 2'- 2.5' in diameter at the most. What makes it so nice a plant are the even spacing of the leaves creating a lacey pattern, unlike the more sloppy pattern of many other fishtails.

As it grows, it has a dark to almost black trunk near the crown, unlike the more commonly grown fishtail palms like urens, maxima and mitis (white tomentum near the... read more
