Sunshine in Rose Form - Light Up Your Garden Today!

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 fade quickly to a pastel cream color and have double blooms continuously and proliferate. 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 the afternoon shade if in a hot climate.


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. 

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 during 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.

sunny KO roses

I received 2 KO roses & the one via AMAZON looks great. The one direct from you guys only looks about 25% alive!

Hey Mike, Thanks for the honest review and for purchasing from our vendor Amazon and us here at Perfect Plants. Hopefully your Sunny Knockout Rosh Bush starts producing soon, since they're just coming out of their winter dormancy. Best Shirley

I am VERY disappointed in my Sunny Knock out rose bushes I ordered. They arrived mostly dead, with most leaves brown and curled up, even though I opened the packaging exactly as instructed. One has died and I'm trying to save the other, but it looks very sickly. The other plants from my order were fine, but the quality and health of the Knockout roses was very poor. I will not order again. They are too expensive for a mostly dead/sick plant.
