Rosa Knock Out - Ground Cover Rose

The 'Knock Out' or 'Radrazz' Groundcover Rose is a very easy-to-grow and versatile landscape rose with a very long flowering period of semi-double blooms in a vibrant shade of Bengal rose with hints of bright red. This tireless rose adorns flower beds without interruption with almost fluorescent bouquets from spring until the first severe frosts. Its dark green foliage, dense and naturally disease-free, has earned it the highly selective ADR Label.*. Also awarded in Genoa and the United States, it is an exceptional, reliable, and carefree variety which deserves a place in every garden, even on the patio.

The 'Knock Out' or 'Radrazz' Rose belongs to the Meilland selection and is characterized by a bushy or ground-covering habit. It forms a dense, bushy shrub that will reach a height of approximately 70 cm (28in) and a spread of 60 cm (24in) at maturity. This variety bears semi-double flowers, 6 to 7 cm (2 to 3in) in diameter, in a beautiful light red shade with hints of pink, revealing a lighter centre populated with numerous stamens. They are grouped in clusters of about ten flowers, which continuously renew on the plant from May to June to October and naturally fall off when faded, giving way to red-orange hips. Their fragrance is light, perhaps more intense in hot climates. The autumn flowering is remarkable, and a lower light angle enhances the flower colour. The foliage, a very dark and glossy green, takes on a purple hue in summer and violet-purple in autumn. It covers long, thorny, and reddish stems.

The 'Knock Out' rose range has many uses: lawn borders, flower beds, slopes, wall crowning, or containers. They can be planted in all soil types, in sunny or partially shaded areas (3 hours of sunlight per day is sufficient). They offer exceptional, long-lasting blooms on healthy, shiny green foliage, often semi-evergreen. Their qualities have been rewarded with numerous awards.

*The ADR is the label of the German Federation of Rose Breeders. The designation is only granted to varieties that have passed the strictest tests in the world. The plants are simultaneously tested at ten different locations, in various soil and climate conditions, for several years. The tests assess hardiness, perennial character, and flowering without the use of any pesticides.
