[kristof p]

Trachycarpus oreophilus, small seedling (2nd winter).

two weeks with moderate freezes and heavy frost between -4°C/25°F and -6°C/21°F and one night with -8.5°C/17°F and days of only 0°C/4°C (32°F/39°F)...

to my surprise i see no damage at all!

today i visited a friend who has a 'large' oreophilus in his garden and this one also had no damage after al the cold weather of late (coldest at his place was -10°C). i think this will prove to be a quite hardy palm!

Wet or dry freezes? I would love to see a picture of his large Oreophilus, I have only seen pictures of this palm on the RPS website. I've had a bunch in pots in my shed this winter where the temp has dropped outside to -16C inside was about -5 for about three or four days with no damage... Pots looked to be fairly frozen. they seemed to come through unscathed. so far.

I left a few of these outside in their little 4" pots last winter (ooops). They didn't look too bad at first. Then they defoliated. Then they grew back from below the soil line, except those that were near the edge of the flat and more exposed. Last winter was the worst since 1996 and possibly 1989 here. In December it was below freezing for about two weeks with two dips down to 13F (-11C). The palms enjoyed some protection from a couple inches of snow for that one. It dropped to 23F (-5C) again in March with no snow cover. To me it appears T. oreophilus is a little less hardy than T. fortunei, but I still have hope for it for our region especially under a tree canopy or something.

still no problem. Oreo's growing like crazy this summer.
