Here's some dramatic proof that not all Needle Palms are the same. Below are 2 Needle Palms in my Zone 7a Delaware backyard, growing side by side. Neither have had any protection for years. Here is what they look like today.
The one on the left, despite some damage this past winter, looks pretty good.
The one of the right, has really suffered these past 2 winters.
2 years ago, the right one looked like this - not as robust as the one on the left, but healthy-looking anyway.
Even in 2014, there was some hope for it!
The only difference in the 2 Needles is the hardier one, on the left, was planted 10 years ago and the less hardy one, on the right, was planted about ~5 years ago (so it had less time to get established before the 2 "vortex" winters.
BUT my big question now is, do I leave this almost dead Needle and try to bring it back this summer? or is it a loss and I need to replace? Since it's already hot and June, I am inclined to leave it and see what happens. But I would say one more bad winter will finish it. Currently, the topmost spear does not "pull" (out) but looks brown. And, as you can see, there is a little growth out a side shoot...
