Ptychosperma elegans

Both my specimens look about the same after 29 degree low. No frost. Both, however, were protected. 1 with heat blasted its way, the other just covered. So, I am not sure that my observations are helpful here. Both are triples and about 6 feet tall with about 3-4 feet of trunk on the largest stem.

Egad!

I must have had much worse.  

The Germinator came to visit, and selected a nice P. elegans that had been in my evil full sun . . .

Next morning, Frosty the Evil Snowman had done his thang, foliage blasted.  

(Day after, 24.8 FF, don't know about that evil night.  Might have been lower.)

Plants in the ground, or under tree cover, okay, so far.

I do some experiments and learning in my garden with palms so you don't have to experience the pain! Look at my old threads to find various observations and tips!

WOW....

from what I'm gathering from you guys, this is one tough plant - more so than I would've figured... I have mine in the ground, heated, and tonight it'll probably drop to around 40f in there (18f outside). I guess I shouldn't be too worried.

Mine looked just fine until about 4 days ago... then it took a complete dump in about 3 days. Now looks dead.

My 7-foot specimen was hurt by 26 F (-3 C) freeze, single night, followed 2 weeks later by a lesser freeze. I finally pulled its unpromising spear today; it was rotting. The plant might have been saved with early fungicide application.

This plant survived prolonged chill of the 2009-2010 winter (down to 30 F) with no difficulty, other than the leaves becoming temporarily chlorotic.

December's average temperature was one of the lowest on record. The rest of winter was pretty warm, no freezes. By way of comparison, two Satakentia almost entirely lost their leaves but are growing. Carpentaria in full sun were damaged, with considerable green left on the leaves. One is definitely putting out new leaves, the other is flowering. Archontophoenix tuckeri (3 of them) suffered leaf damage. They are all producing full-sized new leaves.
