Have a 5 gal. size in the ground which "suckered" (or internally divided) this year. Parent plant--moderate burning. "Pup" --untouched, so far. Wierd.

Mine has since become part of the ever increasing mulch pile. This freeze is getting worse and worse for me  I am most likely down to 50% of my in ground palms half have been lost or not looking very promising.

Two nights at 32 one at 34 last two with heavy frost. I piled mulch up to the growing point and left the fronds exposed. No damage at all. The heliconia on each side is fried.

Last year I lost one 1gal (I think upright form) planted out in a protected area with a 15-hour, 23.3F event. This year a similar-sized 'droopy' form in a somewhat less-protected area appears to have survived a similar onslaught, 14.5 hours and low of 24.1F, as well as a 10-hour, 27F event, and a half-dozen other slightly less severe freezes/frosts. Probably 75% leaf-burn but I mulched the bud-area for safety and hopefully next year the plant will have some more fortitude. It looks as though larger plants can handle mid-20s without too much trouble. But as juvies they obviously are not so easy...and am hoping that in its second year it will grow faster than a snail's pace.

I gave my Farther-In-Law a small plant, about 8" tall in a pot and told him, he could try it outside when it is larger. He has left it outside this winter and it is now, unsurprisingly, dead. It did, however, take several freezes prior to it's decline with temperatures down to -3°C/27°F not seeming to be a problem. When we had unusually low temperatures in early January though, it died almost immediately.
