7 Knockout Rose Varieties
The Knockout Rose is the best selling rose in the country. It is available in many varieties, and is the most disease-resistant rose. All varieties are tolerant of the soil they are grown in, and will do well in almost any climate type. Knockout roses have the longest blooming period of any rose variety, blooming from spring through fall. Winter protection should be given in areas where hard frosts are common, but otherwise the plants can handle most weather conditions, including excessive rain or dry periods. Here is a list of the different Knock Out Rose varieties, and some general information about the species itself.
TIP: Our expert Gardening advisor, Susan Patterson suggests, "Cut knockout roses down to 12 inches in very early spring. They bloom on new growth."
1. Original Knockout Rose
The original Knock Out Rose produces full blooms of a medium red color and rich scent. The blooming season begins after the last hard frost of spring, and can continue throughout the summer until the first frosts of fall, if it is grown in rich fertile soil.
TIP: Susan adds, "Knockout roses prefer loamy soil, and do best in USDA zones 4 to 9."
2. Pink Knockout
This variety has all of the features of the original Knockout Rose, in a lovely pink color. Knockout Roses make an excellent border plant, discouraging intrusion, and providing a sweet-smelling, colorful hedge.
3. Blushing Knockout
The Blushing Knockout produces a pale pink flower, and has the same long blooming season common of all Knockout varieties. It can grow to a total width of 4 to 6 feet, and may reach up to 4 feet high.
4. Double Knockout
The Double Knockout take the original variety one step further, and produces double bloom pods. As the pods bloom, each stem supports two blooms. And a Knockout Rose is self-cleaning, so you won't have to worry about pruning dead buds after they are past their bloom.

Knockout Roses are one of the newest recognized genetic variations on the rose bush. They are comfortable in most soil types, and are even tolerant of excessive moisture, as long as the soil drains well. The plants grow to a uniform domed size of about 4 to 6 feet across, and may be paired for maximum variety of color. All varieties have the same lighting requirements, and prefer full sun, at least 6 hours a day.
TIP: Susan advises, "Plant roses at least 4 feet apart to provide plenty of air circulation."
