Rose 'Seven Sisters' only blooms once a year for me. I think it is the heat. It seems like it bloomed all summer for my dad in PA.
Love in a mist was planted intentionally somewhere that I don't remember. Now it comes up wherever it wants but isn't a thug. Originally I had blue, pink, and white. I purged out all of the pink ones and the white ones died out on their own. That's o.k. I like the blue the best.
