I can't help but think that there is something eerily familiar about the format of this post... hmmm?

Excuse me?

All of the ones in your pictures are Washingtonia robusta, except for number 2, which I believe is a W. filibusta with exceptional hybrid vigor. I've been watching the filibusta since its planting sometime around 2000-2001(It was planted by a now defunct palm nursery). The only true W. filifera that I'm aware of above the Midlands are located at Greenville Technical College.

Here are some pics.

Btw, the W. filifera at Greenville Tech have been there for about six years, and have survived a low of 11 degrees, both in 2010 and 2011.

Thanks for the beautiful photos, the identification and the info! A Washingtonia robusta in Abbeville! Who knew.

I was trying to find a Washingtonia filifera (California Fan Palm) in SC and all I could find to buy was this one with a clear trunk of just over a foot. As far as I know the ones safe to plant in the ground must have at least 2 feet of clear trunk. Do you think this is definitely a Washingtonia filifera?

Thanks a lot for your help! I hope this thread stays on and helps others to identify their palms as well.

The palm in the planter in your last post looks like robusta to me. Filifera is very thready and usually a bit fatter, even at a young age.

If the one above is a W. robusta that would be very disappointing after buying it marked as W. filifera. Same as the seller I too thought it is W. filifera because the petioles and the "teeth" have yellow color to them. I am attaching a link to another palm that's got over 2 feet of clear trunk and that's been offered to me as definitely a W. filifera. What do you guys think?

neonrider I'm no expert but I have one at home now that looks pretty much like that one in your last pic except mine has a little bit of burgandy blushing on some of the frond base. It was sold as a robusta but I think it is a hybrid filibusta leaning more towards a robusa. And with that I believe yours is a hybrid that leans towards filifera. Don't stress hybrids are the best of both worlds - more cold tolerance with faster growth. I'm happy mine is a hybrid I just wish it leaned more towards a filifera.

Washingtonia is monotypic. The two "species" commonly called out are merely phenotypes unsupported by genotyping. If what you want is "filifera", you should check out west. Maybe Yuccado has some. Be aware that this palm is less tolerant of moisture when young than "robusta".
