Jon T 4 Report post Posted January 23, 2007 Six-foot jubaeas: Two nights fourteen degrees, 14 hours below freezing, numerous nights below 20, fifteen nights below 25...drumroll...NO DAMAGE. OK, tiniest bronzing of distal leaflets, ONLY on oldest 2-3 fronds. Ten other jubaeas, from straps in planter to 8 feet, no protection, very light- to no apparent damage, almost two weeks since coldest weather. 1 Quote Share this post Link to post Share on other sites
iwan 207 Report post Posted January 23, 2007 Strap leaf seedling, germinated last summer. In 1g tall pot under shade cloth. 19 of the last 21 days below freezing, with at least two weeks of 12+ hours below freezing each day. Frost was forming under the shade cloth. Measured temps 3' away at 18" (same height as the pot) recorded a low of 15.8F and several days in the mid-teens. No damage. Quote Share this post Link to post Share on other sites
PalmGuyWC 1,482 Report post Posted January 24, 2007 I have 4 Jubaeas, all with woody trunks about 15' and one with 25' of woody trunk. Not touched at 23F and continueous freezing every night. 29 F. here this morning with a white frost and thin ice in a bucket. They were not touched in the 1990 freeze at 14F. This has to be the most cold hardy feather palm, even hardier than the Butias as some of my butias had slight damage on the lower fronds in the 1990 freeze.

GBN 2 Report post Posted October 31, 2011 Hey all, i've got some small jubaea's planted outside in Germany. We had a very long winter at 2010/11 Minimum Temperature at my garden was -15C° (5F) with at least 3 weeks with permafrost not even one minute above 0C°. the Jubaea lost all leaves. But actually it has 3 new Leaves and will go on. I hope the next winter will be normal again. Most Trachycarpus Fortunei had no damage or some leave damage. best regards Andy Quote Share this post Link to post Share on other sites
