edbrown_III Posted January 31, 2007 Report Share Posted January 31, 2007 These will return even from single digits. I saw some in Jax. that recovered from around 14 F. I think below this the canes die. But when it got this cold there was gale force winds. In fact there were some 60 footers up against a building in downtown Jax that survived a 14 F night in 81 but 83 killed them ( high winds) I saw some at the college that largely survived 89 here in Jax ( North Fl) 4 nights 3 in teens ( 16, 17, 19, 22 if memory serves me) there canes werent destroyed. You can get a 10-12 foot plant in a decade if you use good fertilizer and have it in a wet area so hang in there Best regardds, Ed Link to comment Share on other sites More sharing options...
AJQ Posted March 19, 2007 Report Share Posted March 19, 2007 I have one planted out here. It got badly sunburnt which I think has not helped when ther colder weather came. It has seen -4.8oC/23oF. It looks quite yellow now and new spear pulled away. Perhaps if I can get one which is Acclimatised to the sun then it may well stand a better chance in the colder waether. Regards Andy. Bangor, Norin Iron Zone 9a Min temp normally around -3 Degrees C, rarely -6C. Only 2 x -2.0C so far, verging on 9b this year. No snow or Frost this Winter.

mnorell Posted January 6, 2009 Report Share Posted January 6, 2009 My small plant has only endured 27F so far (with no damage), but I did read an old Principes that gave data from a big freeze in Dallas in I think 1958...it stated that (the then-named) Paurotis had died to the ground in single digits and brutal, lengthy cold, but came right back from the roots.

NorthFlpalmguy Posted February 11, 2015 Report Share Posted February 11, 2015 I have around 10-20 in 3G pots (but 1G size) under oak canopy but they still get a nice layer of frost. Unprotected, they have gone through nights of 20-22 for multiple hours. There is visible damage to some leaves.. maybe 10%. Not nearly as bad as I first expected. I have some unprotected washingtonia robusta seedlings next to them and 99% of the hundreds I have are dead. Link to comment Share on other sites More sharing options...

NorthFlpalmguy Posted February 12, 2015 Report Share Posted February 12, 2015 Takes a while to see damage on A. wrightii I'm surprised about your washy's...that sucks Yes, I think they're showing more of the December hard frost damage now but they are still doing better than I expected. I was surprised myself as I have only seen robustas torched like one other time and I used the same seed source both times located around Orlando. I do not really believe in cold hardy acclimation but when I get my seeds locally, I hardly lose any. I really do not care to have too many robustas but it's nice to have a few dozen per year. I have a few hundred pure Fillys to replace them so all is good. Link to comment Share on other sites More sharing options...
