Addy, my crepe myrtles have not come back yet, and I noticed yesterday some growth from the base of the 2nd of my 4 butterfly bushes. One is growing, now I have one more showing growth, so I guess I'm not going to give up on anything until the end of June.
Keith, what kind of "hat palm" do you have in your pond that comes back every year? Truthfully, I think the ponds/bogs saved plants last winter, rather than froze them. Just my opinion, as nothing in my bogs or pond did not come back. In fact, one of my lilies that I put in the basement in a tub of water, with a light on it for 12 hours a day seems to be dead now that it's in the pond. I suspect it is the tropical one, and maybe I put it out too soon? But, water temps were very warm when I put it out there. Very strange! And, other lilies are growing, but none are going crazy just yet, all leaves are still red, none are green, and all are small in comparison to what they will look like once they are growing well. Just a much slower start this spring than last spring, but considering we had 80's in March last year might have something to do with that! LOL
