Product Description
As the only fragrant member of the Knock Out® family, the Sunny KnockOut Rose Bush adds not only a burst of cheerful yellow but also a sweet scent to your garden!
This cultivar’s fragrant, bright yellow flowers that fade quickly to a pastel cream color and have double blooms continuously and proliferous. The sunny knockout bloom color stays more intense during cooler times but the golden yellow color stays year round.
Flowers blossoms appear in early spring. The yellow knockout rose blooming season is in spring and summer.
This beautiful rose bush makes for a superb low hedge. The dark green, semi-glossy foliage contrasts nicely with the bright yellow blooms, and you can enjoy this deciduous bloom cycle all summer long.
Grows in an upright habit during most times of the year and the yellow knock out rose turns quickly to pastel once the summer heat settles in. You can even grow this flowering shrub in afternoon shade if in a hot climate.
How to Take Care of Knockout Roses
Knockout roses require full sun and well drained soil types. You can amend your native soil with our Rose Soil Mix to keep those roses growing happy and healthy. They can grow up to 3-5 feet tall and 3-4 feet wide at maturity.
Grow the yellow rose bush across the United States in USDA plant hardiness zones 5-10. It has great winter hardiness. The best time to plant a rose bush is in spring or fall.
Like the other KnockOut family members, the Sunny Knock Out Rose Bush has extraordinary resistance to common rust, mildew and black spot foliage disease resistance. It is also drought tolerant once established.
Pruning roses should take place in late winter or early spring. Cut back your rose plants to about 1 foot tall. A planting site with an open area will help with air circulation and aids in the health of the plant according to Southern Living. You can prune this rose shrub into a yellow knockout rose tree if that is your desired shape. Check out our blog on Winter Care for Roses.
Fertilize your rose bush near the root ball once a year in early spring with slow release fertilizer to give it a nice boost for growth and flower production. Water thoroughly the first year of planting to establish a strong root system.
Shop the Sunny KnockOut Rose for sale. It is easy to grow and we highly recommend it for beautiful yellow roses. Even someone without a green thumb could grow this knock out rose.

If you have never heard of the Knockout Rose, then you wont be disappointed with these plants. I called ahead and spoke with Natalie, who assured me their roses were very healthy. I placed my order and my roses showed up in 3 days. Impressively packed my roses were. I will order again as my grandson is still making my rose garden.

I was not happy with the state of the plant. I admit it was healthy but feel for the high cost of the plant and shipping…almost $100.00… it should have had some buds and new growth. It had neither. It is planted but still no signs of buds or new growth.

Hello, I think the rose bush is getting used to a new place, although it is not blooming. This is my first experience and it will be a pity if the rose does not take root
