I thought I remember hearing Or reading  that there was a native stand of w. Filifera in the very south of Utah. Is that true?

Seems like I’ve read that before on some more obscure websites, it isn’t true though. The nearest native stand is in Moapa NV which is less that 40 miles from the border at the nearest point. 

Found a healthy, old robusta today. Crazy they’ve seen single digits for days. Most vanquished.

Wow. Have you seen it produce seeds?

I didn’t seem any seed on or below it, however it did appear to have seeded; there were dry inflorescence stalks on it. I’m going to keep an eye on it. It’s pretty far away from any other washingtonia. Could potentially be a good genetic strain to utilize.

I image it was too cold last winter for it to flower this year. It snowed several times followed by low teens. 

 

Here are some of the best examples of the Robusta/Filibusta in the St George Utah area, these two areas are on opposite sides of St George City, the further north, like Washington City, where the In & Out is located, the colder the zone becomes. Hurricane, Utah, part of the St George Metropolitan Area, is a Zone 8a, possibly borderline 7b/8A  but W. Filifera have basically naturalized themselves in Southern Utah.
