I planted two rose of sharon trees - a lavender/purple one and a pink one. They flowered beautifully last year. So far this year, only the pink one is growing back. It has a number of leave ssprouting out. The purple one does not have a single green leaf on it. I tried to bend a couple of canes and they seem dead.

Maybe I planted this a little above ground and so the winter cold killed it? Does any one know if this particular tree take a little longger to spring back or is it dead? How can I check?

Thanks for your help.
