I was pleasantly surprised that it came back! The spot it is in is very hot and dry. I think the rock mulch is beneficial for it too. I also could have been lucky thiswinter too, it was thefirst winter they were plantedand it was rather mild and we didn't get asmany freeze thaw cycles as we do some years. So hopefully they will be perennial but you never know with zeric plants in NE. I tried Agastache cana from seed three years in a row and this past winter has been the first I have actually had some return. It could be the spot and it could be that I used rock mulch where they are planted as well. The first two times they were in more exposed spots and didn't have a rock mulch. I have also heard that pools might increase the hardiness zone near them because the water doesn't freeze all the way so can radiate some warmth to the ground near by. Not sure if that has any thing to do with the ice plant survivng. You can see how close they are to the pool in this pic.
