Double Knock Out® Rose 1 Live Shrub – 2 Gallon Pot – Rosa 'Radtko'

Double Knock Out® Rose (Rosa 'Radtko') is a repeat-flowering ornamental landscape shrub known for its vibrant cherry-red blossoms, layered double flowers, and attractive dark green foliage. Part of the Knock Out® Rose family, this perennial shrub brings rich red color to sunny rose gardens, foundation beds, and mixed landscape borders.

Throughout the growing season, Double Knock Out® Rose produces abundant clusters of bright cherry-red flowers with a fuller, multi-petaled appearance than the original Knock Out® Rose. Its double blooms contrast with dark green foliage, creating a colorful display in ornamental landscapes. Under favorable conditions, flowering repeats from spring through fall, although bloom timing and intensity may vary with local climate and seasonal weather.

Double Knock Out® Rose generally performs best in full sun and fertile, well-drained soil. It prefers moderate moisture and good air circulation. Its rounded, bushy growth habit makes it suitable for flowering hedges, mass plantings, garden borders, foundation beds, and large outdoor containers with adequate drainage.
