The knock out roses are one of the easiest rose to grow and yet very showy. Plant them, water them and they grow! That's easy!

Unable to find white and yellow knock outs at area nurseries. They are easy to maintain and able to hold up to the harsh winters in Ohio, Very Low maintenance

Knock out do best in the Texas heat and I love the color

Have a white garden in Zone 7 and other White roses have not made it through the winter in this specific location. Knock outs can handle anything.

I bought the white out rose two years age and they have since grown to almost three feet, continuously blooming from early spring until freeze, even 100 deg. weather.they are planted alternately with the red double knockout rose. I purchased about 25-30 rose. Beautiful winding hedge! love them.

Fantastic blommers
When I received the plants I was concerned about their size. I planted them in the fall and left them alone. Now in May they are 2 feet tall and wide and completely full of repeating blooms. What a nice show, I wanted a hedge and they are just what I wanted. Very good value and a great performer.

Beautiful and classy!
These replaced our pink knockout roses that had grown so big you couldn't call them bushes any longer. These have just as many blooms and are so much more classy than the hot pink ones! Beautiful!

White Out Rose
I'm very pleased with the White Out Rose. It is blooming right now in our rose garden. We are quite happy with its growth and the number of flowers. It has done really well in the short period of time we have had it.

Patience is required
I have grown several of these in different locations. They take 3-4 years to develop full potential but are worth the wait.

Greatest white rose!
I bought a number of these White Out Roses. They perform beautifully with non stop blooms. No disease problems at all. And my neighbors give constant compliments!

Happily Living in South Carolina!
The two White Outs that I bought last spring are doing very well. They have shown vigorous growth and have flowered almost continually since February. The plants are a little misshapen but that can be easily corrected with pruning.
These are the first roses I have had shipped to me and they were very small plants but they obviously took off during the summer last year and by fall they were quite substantial. I do miss a regular rose with all the petals but these singles are lovely in their own right. I would definitely buy them again!!

I already knew that I love knockout roses, so I had to have some whites to go with the others. They came in an the small side, but in perfect shape and immediately started giving me blooms. They're growing by leaps and bounds and are so pretty! Once again, Stark Brothers has given me exactly what I wanted!
