I moved from the country back into town and I bought 5 knockout rose plants from you for out there. I sold my home in April and the roses were in full bloom. They were 4 yrs old and full growth. I have to have them for my new home. I might add....the beautiful roses were a selling point for my farm?????

Do Knock Out Roses have thorns?
Doug K on Feb 14, 2017
BEST ANSWER: Yep, lots of them nd they are kitten claws -- very small and sharp! But I agree that the benefits of having such a trouble free prolific bloomer way outweighs the minor annoyance of the thorns.
do you have this rose in larger containers ?
Tim K on May 19, 2020
BEST ANSWER: We appreciate you reaching out to us. unfortunately no they are young plants and only offered in the 4 inch pot at this time.

If you have any further questions please don't hesitate to reach back out to us. Have a great day!
How large will these grow in year 1?
John Y on May 1, 2019
BEST ANSWER: Depending upon the conditions, it can grow up to 3'. Mine did that in loamy soil, full sun, even water/rainfall and Tre-Pep fertilizer.

Absolutely love this rainbow knockout rose! I bought one for myself and then again for my sister in law and when the arrived they were very healthy. Has been one year in a harsh illinois environment and they're both still going strong.

Knock out Roses
I planted these roses about 3 seasons ago. They are really coming into their own this year. They just need a simple trim in the early Spring then they are good for the rest of the season. They will reward you with continuous blooms. They have a very nice shape with a tight coverage. Long lived and gorgeous.

Knock Out Rose
This is the most beautiful, trouble free rose I have ever grown. My plant is just one year old, it is about 15 inches high and covered with blossoms all season. I am heart broken to learn that it is no longer available.

Well, so far so good. I purchased them last year and I was a little apprehensive because they were so small (4" pots). But, they came back this year and they look beautiful. That is why I purchased the knock Out Rose Collection.

Knockout Roses
I am most pleased with the knockout roses. They are a wonderful addition to our landscaping. They were exceptionally pretty after the weather cooled a bit, but performed marvelously all year. I would recommend them to anyone seeking a beautiful addition to their landscape.
