Double Knock Out® Rose 1 Live Flowering Shrub, 2 Gallon Pot – Rosa ‘Radtko’

Double Knock Out® Rose (Rosa ‘Radtko’) is a deciduous flowering shrub rose admired for its vibrant cherry-red double blossoms, abundant repeat flowering, and attractive green foliage. This popular landscape rose combines the recognizable flower color of the Knock Out® family with a fuller, double-petaled flower form. Its bushy, rounded growth habit makes it suitable for sunny borders, foundation plantings, rose gardens, and ornamental landscape beds.

From spring through fall, Double Knock Out® Rose produces repeated flushes of bright cherry-red flowers that stand out against its healthy-looking green foliage. Its double blossoms create a fuller floral appearance than the original single-flowered Knock Out® Rose. The foliage generally maintains an attractive appearance throughout the growing season, and this selection is known for strong resistance to common rose foliage diseases. Disease resistance does not guarantee complete immunity.

Double Knock Out® Rose performs best in full sun and fertile, well-drained soil. It prefers moderate watering, particularly during establishment and extended dry periods. Its naturally rounded, bushy habit makes it suitable for grouped plantings, flowering hedges, and appropriately sized outdoor containers. Although foliage may persist longer in mild climates, this rose is generally deciduous and may become leafless or dormant during winter.

Each order includes 1 live Double Knock Out® Rose supplied in a 2-gallon nursery pot (G2).
