Washingtonia, should be harmless unless they get blown down by
Santa Ana winds!

Thanks, Saltcedar! Your answer is very much appreciated.

Do you know if the palms are:
- California Fan Palm (Washingtonia Filifera)
or
- Mexican Fan Palm (Washingtonia Robusta)

Washingtonia robusta I believe.

I would say W. robusta too.

Thanks for your help saltcedar and texasflip.
Now that you've helped me identify the palms, I'm concerned that they will grow to heights of 90 feet. Then they'll be too tall for me to take care of, and I'll need a professional arborist to cut the dead palm fronds. But that's a different issue.

I admit it can be hard to tell the difference when the palms are this young, but I'm leaning more towards W. filifera. The trunk seems a little to fat and the leaves seem a little to big for W. robusta. But I'm in AZ and I think the palms look different here than in Cali.
