About

The Double Red Knockout rose (Rosa 'Radtko') is a popular and hardy shrub rose that stands out for its continuous blooms, disease resistance, and low-maintenance requirements. Ideal for gardeners of all skill levels, this rose variety is sure to add a striking burst of color to any landscape.

The Overall Plant

The Double Red Knockout rose is a compact, deciduous shrub that typically grows to a height and width of 3 to 4 feet. Its dark green, glossy foliage creates a beautiful backdrop for the stunning red blooms. This rose variety is known for its exceptional disease resistance, particularly to common rose afflictions such as blackspot and powdery mildew. The hardiness and low-maintenance nature of the Double Red Knockout make it an excellent choice for gardeners seeking a hassle-free, eye-catching addition to their landscape.

The Flowers

The Double Red Knockout rose produces abundant, double-petaled red flowers throughout the growing season, from spring to frost. The blooms have a mild, pleasant fragrance and can reach up to 3.5 inches in diameter. Unlike many other rose varieties, the Double Red Knockout requires minimal pruning and deadheading, as it is self-cleaning and continuously produces new blooms. This prolific bloomer attracts pollinators such as bees and butterflies, enhancing the biodiversity of your garden.

The Fruit

Unlike some other rose varieties, the Double Red Knockout does not produce hips or fruit. This absence of fruit allows the plant to focus its energy on producing an abundance of vibrant blooms throughout the season. While the lack of fruit may be seen as a drawback for those seeking to attract wildlife, the continuous flowering display more than compensates for this by providing an extended season of visual interest and color.
