I had 3 or 4 "Polar Vortex Winters" since I got big into marginals in 2007. All my stuff would come limping into spring khaki tan and fried.

Up here, even a Trachy takes 2 growing seasons to replace catastrophic loss (when all the fronds are killed). So, two consecutive 0F winters just really set palms back. I believe it's just that sort of thing that caused my S. Palmetto (16 years in the ground from bareroot strapleaf plant) to turn into a Minorized Palmetto. ...Meaning, no trunk. I think it had a very near-death experience and when it came back, it just wasn't ever "right" again. It got stunted. On the good side, it's still green and sends out pretty fronds.
