See what our great customers had to say about the Rosa Radtko 'Knock Out Double Red'.

Melissa's Review
Location: Mount Airy, MD

What a sensational plant! I ordered 16 Double Knockout bushes from Sooner last spring and planted them along the front of the house. WOW!! What a gorgeous show all season long -- and the first season too! Neighbors and friends couldn't believe that the bushes were still blooming into November.

Thanks to Sooner too! The bushes arrived full, healthy and in excellent condition. I've never had mail order plants arrive so healthy and vigorous.

ROSE 'DOUBLE RED KNOCK OUT'

Double Knock Out® has twice the number of petals as Knock Out®, presenting a fuller, richer,cherry red inflorescense that is simply breathtaking. Blooms maintain a continuous show of color from early June to hard frost, with beautiful foliage almost year round. Compact and upright fashion, more winter hardiness and shade tolerance.
