Double Red Knock Out® Rose

Bring vibrant, continuous color to your garden with the Double Red Knock Out® Rose (Rosa ‘Radtko’ PP16,202 KO). This standout shrub rose offers lush, double-petaled blooms in a rich cherry-red hue, blooming from late spring through fall. Its compact, bushy habit and exceptional disease resistance make it a favorite for both novice and seasoned gardeners.

Key Features:

  • Abundant Double Blooms: Features full, double-petaled flowers in a vivid cherry-red color, adding a classic touch to any landscape.
  • Extended Bloom Time: Flowers continuously from late spring until frost, ensuring a season-long display of color.
  • Compact Growth Habit: Grows to approximately 3–4 feet tall and wide, making it ideal for borders, hedges, or container planting.
  • Disease Resistance: Exhibits strong resistance to common rose diseases like black spot and downy mildew, reducing the need for chemical treatments.
  • Fragrant: Emits a light, spicy apple fragrance, enhancing the sensory experience of your garden.
  • Pollinator-Friendly: Attracts bees and butterflies, supporting local pollinator populations.
  • Cold Hardy: Thrives in USDA Hardiness Zones 5–9, making it well-suited for the Chicagoland climate.

Care Tips:

  • Sunlight: Plant in full sun (6–8 hours of direct sunlight daily) for optimal blooming.
  • Soil: Prefers well-drained, loamy soil enriched with organic matter.
  • Watering: Water regularly during the first growing season to establish a deep, extensive root system. Once established, water as needed to maintain soil moisture.
  • Mulching: Apply mulch around the base to retain soil moisture and regulate temperature. Mulching late in the fall helps protect the crown during winter.
  • Poda: Prune in early spring to maintain shape and encourage vigorous new growth. Remove spent blooms (deadheading) to promote continuous flowering.

Whether you’re creating a vibrant hedge, a colorful border, or a stunning container display, the Double Red Knock Out® Rose offers beauty and resilience with minimal maintenance. Its long-lasting blooms and hardy nature make it a must-have for any garden in the Chicagoland area.
