Hydrangea

I bought this hydrangea four years ago. I was attracted with the pink color of it's flowers. This is a perrenial plant so it comes back every year just like the roses and day lilies. I prefer buying perrenial plants than the annuals. I don't wanna waste my money with plants that will die on winter and don't come back. There is also a blue hydrangea and I want to have that too to add to my flowers.
