Double Red Knock Out Rose 1 Live Plant – Rosa ‘Radtko’ – Quart Pot

Double Red Knock Out® Rose (Rosa ‘Radtko’) is a flowering landscape shrub valued for its vibrant cherry-red double blossoms and glossy green foliage. Each flower features multiple layers of petals, creating a full, rounded appearance that adds rich color to rose gardens, ornamental borders, and foundation plantings.

This repeat-blooming rose produces successive flushes of flowers from late spring through autumn under favorable growing conditions. Its bushy, rounded growth habit makes it suitable for mass plantings, mixed shrub borders, low ornamental hedges, and outdoor containers. The foliage provides an attractive backdrop for the colorful blooms throughout the growing season.

This listing includes one live Double Red Knock Out® Rose in a quart-size nursery pot (QT). The shrub performs best in full sun and prefers fertile, well-drained soil with moderate moisture. Seasonal pruning, dormancy, and leaf loss may affect its appearance at the time of shipping.
