Help identify young Washingtonia Palm

[MSX]

 

Hello could somebody please tell me what species of Washingtonia palm this is. Filifera, robusta or × filibusta? Thanks a lot

Can't say,  but Welcome to Palmtalk !

Looks like a pure Filifera to me, or at the very least a Filifera-dominant hybrid. I don’t see any Robusta traits at all in that young specimen though.

UK_Palms, thanks a lot for your help!

Cold hardy Filifera is definitely great, especially after the winter we had

Yep. Pure filifera.

Hello palmtalkers! I got one more young Washingtonia today (1 1/4" trunk base diameter & 4" trunk height) that will be planted outside to its permanent location next month, and once again I need your help to confirm the species. The choice was very wide, and as I'm now in the market for pure young cold hardy filiferas for my house so I picked the one that has got the greenest petioles and with the leaf segments deeply cut out, below the 50% mark. But I noticed the lowest petiole has some brown spots of antocianes (robusta genes or still common for filiferas too?). I know it's still super small but does it look like a young filifera in general? And another question, is it okay to plant Washies outside (BSk, 7B/8A) to a permanent location at such a young age?Thanks!

The second one is probably a Filifera dominant hybrid that results from a Filifera x Filibusta cross, or from Filibusta x Filibusta that is just showing more Filifera dominance. I don't see much Robusta in it at all, apart from a slight hint of red on the petiole bases. I suspect its growth habit and hardiness will be very much like Filifera though, even if it is technically a hybrid.

Ben, thank you again for your expertise! Yes, I read that the two Washingtonia species hybridize freely, making identification of cultivated palms difficult but apart of the exterior characteristics, are the Filifera hybrids considered to be more or less cold hardy than the pure Filiferas?

[aegean]

Of course all filifera / robusta hybrids are either equal or less cold hardy than pure filiferas, depending on how dominant the filifera part is.

Generally W. filifera is much more cold hardy than W. robusta.

Hi there I recently got a Washingtonia palm it was advertised to me as California fan palm but now I am having second thoughts, I would like to know if it’s robusta filifera or filibusta, I know it’s likely still to young to tell what type it is but any educated guesses would be great.

[aztropic]

You definitely have a robusta. (Mexican fan palm)

California fan palms (filifera) do NOT have any red on the petiole bases. Here is a picture of a California fan I have in a pot to illustrate.
