The first time I saw these beautiful roses was on our vacation in Tennessee. I fell in love and bought 4 praying they'd do well in our hot zone in Clearwater, Fl. I was happy to see they grow in our zone, maybe won't put them in our full baking sun. Very excited and hope they do well.

I bought two of these rose trees and I've loved them since I laid eyes on them. I planted them in an extra large container. 1 plant to each and then made a surrounding for my front entrance. They look beautiful and they suit my yard.

Plant 'em and forget 'em! That is my motto and these plants truly live up to that standard. We live in a condo and have them all over the place. They're beautiful... I never get tired of them!

Precisely why I chose the Knockout family of roses for the hedge that I just finished. I want to enjoy them, not spend all my time deadheading 50 rose bushes! (Only 35 in the hedge, the others are in various beds all over the yard.)

(Full disclosure: Mr. Radler has been a personal friend of mine since the 1970s. I bought an original Knock Out in 2000, the first year it was on the market and the AARS winner. My following review is not based on that. It is about my complete satisfaction with this rose. Thank you.) I' started gardening in 1988 and had a few roses during the years but found them too maintenance-heavy. (except for "Bonica," a landscape rose by Meidiland®) In 2000, the yea I planted it, it grew to about 4 ft. and bloomed beautifully. While working near it that year, I smelled a very nice fragrance and wondered where it cam from -- dryer sheets? Nope. It came from my Knock Out! To me, it smells faintly of cloves., a scent i love. That same year, many people stopped on their walk in front of my house and admired it and asked about it. It was a showpiece, for sure. One fall, I cut it back to 1o or 12 inches, but the following year it didn't grow as tall, so I have stopped doing that, hoping it will grow to 4 ft. again. It never did. My fault? Probably. I never fertilize it. Its biggest plus is: on two separate years, it died back to the ground over winter but still grew back with roses that bloomed from Spring till Fall , and every year since I planted it. Talk about hardy and with no maintenance! (Suggestion: make sure what you buy is on its own stock, not a grafted one.) Gardening is no longer a major pastime for me. I'm nearing 80 and don't have the energy nor the stamina I had in 1988. (Some of you reading this can relate, I bet.) I've always planted flowers in my gardens and said to them, "Grow for Bernie." If they do, and I like it, fine. If not, it's replaced with some other flower. I don't 'baby" flowers. I gave Knock Out a 5 rating. In my opinion, it deserves the highest. I love it. Sincerely, B. R. W.

These roses remind me of my mother's roses. My mother's bush was loaded every year, and she had a circle of jonquils planted around them. My daughter brings me flowers for my garden every year for Mother's Day, These roses will be the gift of the garden that keeps on giving. She gave me one rose bush last year among other flowers, and this year, she brought me two more rose bushes, and as soon as she left, I was out there planting them. She gave me twenty more pots of flowers to plant around them in multiple colors. I am so proud of these gifts that keep on giving. I am also an artist and love to paint flowers, flowering landscapes, so this is another way this gift keeps on giving. When in bloom, I take plenty of photos of the flowers for my paintings.
