I planted 2 DoublePink Knockout Roses this spring and they did well over the summer despite all the rain in June/July. I'm already thinking of winter protection....I live in northern MA, (lots of snow and ice), and I've read that I may need to "protect" these roses for the winter. What type of protection do you recommend?

On a side note, one of the plants bloomed a group of red flowers. It was beautiful, but definitely not pink like the rest of plant. Is this typical for Knockout?

Thanks,

Shelli
