Hilo Jason Posted August 19, 2011 Report Share Posted August 19, 2011 I had several 1 gallon plants in the ground this past winter that saw a low of 31 and 3-4 nights of light frost and they showed no damage at that point. Link to comment Share on other sites More sharing options...

doubravsky Posted December 24, 2013 Report Share Posted December 24, 2013 I had three VERY small palms in ground in 2007.... no damage at all with temps 26-28. No damage in the five years since.... this palm is pretty hardy for a dypsis!

No damage in the five years since.... this palm is pretty hardy for a dypsis! Thanks for posting that. This is perhaps the best dypsis for me up North, it really grows well. Dave, you forgot to tell people how you got snow in 2007 at 1700 feet, and how your entire yard away from your heated pool turned brown, not to mention the dypsis plumosa growing in the bunch below got killed whereas the ambositrae survived just fine. That says a lot. Proof of how nice Dave's ambositrae are, I just saw them yesterday: Link to comment Share on other sites More sharing options...
Xhoniwaters1 Posted January 31, 2014 Report Share Posted January 31, 2014 Small 1gal seedling in pot. Left out exposed to the cold but stayed dry under shelter. My thermometer saw 23 but my guess this one saw somewhere between 24-26 degrees. Around 9 freezing hours total. Pot froze solid. Zero damage.

Ahhhh, nice to hear that, I'm pretty sure this is the hardiest dypsis next to decipiens based on my own observations. Link to comment Share on other sites More sharing options...

Ahhhh, nice to hear that, I'm pretty sure this is the hardiest dypsis next to decipiens based on my own observations. Yeah I intentionally left out one of my small seedlings to see how it would handle some cold, but our temps ended up dropping way below the forecast. I brought it inside the next morning thinking it was toast but low and behold never showed any signs of damage.Definitely thinking it could have endured a longer freeze duration and maybe lower temperatures. Based on what I have read with these, I am believing these show some variability with the cold.

Alicehunter2000 Posted February 1, 2014 Report Share Posted February 1, 2014 I'm assuming that by real you mean from Madagascar seed and not the fine leaf form.? Floribunda?

Xhoniwaters1 Posted February 1, 2014 Report Share Posted February 1, 2014 I'm assuming that by real you mean from Madagascar seed and not the fine leaf form.? Floribunda? Real as in not Dypsis plumosa, which was sold as ambositrae a while back.

Xhoniwaters1 Posted January 18, 2015 Report Share Posted January 18, 2015 3ft ambo in the ground...had some sun stress prior to freeze. One night at 23 degrees and it's defoliated. Spear still green and looks to be opening healthy. Bet if it was 100% from the start damage would have been a lot less.

SHEP Posted March 20, 2022 Report Share Posted March 20, 2022 Significant damage to trees under cover at 27 degrees only one night, second was 28-29.. Spear ok, and proximal petioles ok, but leaves fried about half way through. Damage appeared about 3-5 days later. So, it will recover, but these were 7-9 feet tall and healthy & happy. New spears already growing. Cecile Link to comment Share on other sites More sharing options...

But the one I have, I covered completely with a bucket so it's fine. Link to comment Share on other sites More sharing options...
SHEP Posted March 21, 2022 Report Share Posted March 21, 2022 No damage to the 2' tall Ambo next to fence, in a raised bed, it had a Frost cloth over posts, which extended to ground, with no damage. My other multi-trunked drop dead gorgeous Ambo looks terrible. I will have to take out. Cecile Link to comment Share on other sites More sharing options...
