Hyphaene turbinata hardiness

[Mauna Kea Cloudforest]

I finally managed to find a beautiful hyphaene, it was sold to me as hyphaene turbinata. I wonder how hardy these palms are. My garden is a cold 10a, we drop to 31F about once or twice a Winter with 27-29F every 10-15 years. Would this work here in an open fully exposed part of the garden? I do have a milder 10a higher up the hill but lower down it gets much hotter. I have sandy fast draining soil that leans towards a slightly alkaline pH but low in calcium and rather devoid of nutrients.

Hyphaene coriacea

Yes. According to Kew that's what it is

Crap, I read the hardiness reports on PalmTalk for coricea, for a palm that looks this tough, the lack of frost tolerance is really surprising. I guess it's going to have to go on top of the hill where it's frost protected and stays above 32F most of the time.

Winter did damage mine when it saw 26f. Then I dug it up and moved it in spring and that did it in. After moving it it was dead in less than a week. From what I hear about these is that they need high heat in order to grow well too.

Crap squared! Oh well, I'm allowed to make one or two dumb purchases. I have spots that are full sun and are pretty protected, but I just don't get the heat. It's a pretty good sized plant, maybe it will acclimate to the cool weather.
