The Double knockout rose was contributed by Margaret, thank you!

This is a modern shrub rose, and like many of the modern roses, it's unfortunately lacking in fragrance. Still, it's a lovely rose to look at, and adds a nice splash of color to the garden. You will get a repeat flowering later in the season, with any luck.
Just make sure you deahead it, and remove old blooms to help encourage it to repeat. Easy care, this has a reasonably compact growth habit, and looks nice in a mass planting.
