Kolorscape Kardinal Rose

Kolorscape Kardinal Rose (Rosa 'KORsixkono')

Kolorscape Kardinal Rose is a landscape shrub rose that delivers strong, cardinal-red color in repeat flushes, keeping sunny beds looking finished for months. Its blooms arrive in clusters, so the plant reads full and vibrant even from a distance. The shrub holds a tidy, upright-to-bushy shape that is easy to place in borders and foundation beds without constant shaping. If you want a bold red rose with dependable performance and a straightforward care routine, this one fits the role.

Distinctive Features

This shrub rose produces abundant clusters of rich red, semi-double to double blooms that keep coming from late spring through fall, with especially heavy flowering in warm weather. The flowers hold a cupped form as they open, then shed cleanly, helping the plant stay neat with less deadheading. Glossy green foliage provides a polished backdrop and supports a dense, symmetrical habit that looks intentional in the landscape. Mature size is typically about 3 to 4 feet tall and 2 to 3 feet wide.

Growing Conditions

• Sun: Full sun is best for the strongest bloom and cleanest growth, and it can tolerate partial sun with fewer flowers.
• Soil: Plant in fertile, well-drained soil, and improve heavier soils with organic matter for best performance.
• Water: Water deeply during establishment, then water when the top few inches of soil are dry while avoiding consistently wet soil.
• USDA Zones: Zones 5 to 11.
• Spacing: Space about 2 to 3 feet apart to support airflow and let the shrub fill out evenly.

Ideal Uses

• Focal Point: Use as a focal point in a sunny bed where cardinal-red bloom can anchor the color palette from late spring through fall.
• Mass Planting: Plant in groups for a bold sweep of red that reads well from the street.
• Foundation Beds: Adds repeat bloom and a tidy, mid-height structure along the house without overwhelming the space.
• Mixed Borders: Pairs easily with perennials and shrubs, providing strong color and a clean evergreen-like presence while in leaf.
• Containers: Works well in large pots where the compact habit and clustered bloom can be enjoyed up close.

Low Maintenance Care

• Pruning: Prune in late winter to early spring to shape the shrub and encourage vigorous new flowering growth.
• Deadheading: Deadheading is optional since spent flowers shed cleanly, but light cleanup can improve tidiness between flushes.
• Watering: Water at the base to keep foliage drier and support healthier growth through humid weather.
• Feeding: Fertilize in spring and again after the first bloom flush to support repeat flowering.
• Mulching: Mulch to conserve moisture, suppress weeds, and moderate soil temperature around the root zone.
