23 degrees, some leaf damage on a young plant. Minor browning. No protection.

10 days after original post most of the leaves are turning brown. Damage is showing much more. Plant will probably live

27F (possible a few degrees cooler) 5 hours- unprotected seedling about 5 years old 2' tall: All leaves pretty badly discolored but doubt it will die.  Now it's been a week, and plant will obviously live, but only one leaf left (rest all toast)

In the ground, light overhead protection, about 5 feet of trunk.  Probably exposed to 23/24F and no damage.  When it was younger, it was damaged at 25 F.

I had one freshly planted this october from a five gallon pot in the lawn near a large Rhododendron which shelters it a bit. It received several 32°F nights and two 27° lows and had been covered with frost, no damage at all and still showing active growth in McKinleyville Ca.

I have both "Nepal" and "Khasa Hills" varieties all over my yard.  I originally saw what appeared to be leaf damage...but nothing.

All look great.

24.9 F recorded in protected area of my yard.

1/28-  Upon further inspection- this plant is located in an exposed area- against a North facing fence

Tiny seedling receiving some shelter. Multiple hours below freezing with ultimate low around 20 degrees. 90% damaged but looks like it will live.

Low of ~19F. 12 days straight of below freezing temps. No overhead protection. 1 plant in the ground had no damage. Plant is about 3ft tall. Will have to see how this one looks by mid summer because I'm really surprised that it made it through this winter unscathed.

Trachycarpus martianus grows wild in much warmer climate zones, lower altitudes, then other Trachycarpi. The T. martianus Khaza Hills from near Cherrapunjee grow in a very warm climate where also Caryota gigas grows wild. They grow near a big waterfall but I have not seen them despite that I have been there. Well the other T. martianus from Nepal.

Nepal form some minor damage to lower leaf at 26.6F fully exposed. Khasa hills was untouched because of nearby bamboo.

This species turns out to be latisectus, not martianus. This explains the damage.

Axel are you saying latisectus is more tender than martianus?

I don't have enough data points to be sure, I just have this one freak trachy that got damaged when my bismarckia just 30 feet away was left untouched. The damage seems consistent with what Glenn is reporting above for the 2007 freeze in Modesto. It's minor, and mine has already grown out of it. And none of my martianus, both Khasia hills and Nepal form were affected. Another latisectus under canopy was also undamaged.
