  1. Melissa - Mar 22, 2008
    Mount Airy, MD (Hardiness Zone: 7)

    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.

    Blooms and blooms and blooms all pests, just wonderful plant.

    Sadly ,It did not make our brutal winter (zone 4) but last summer it was gorgeous and full of blooms, and well grown. Sooner gave me credit for it . Perhaps what I covered it with was not enough considering the extreme cold we had last winter.
