Radtkopink Double Knock Out Rose

Rosa 'Radtkopink'

The Story

Plant Bio

The Knock Out family of roses are celebrated for their exceptional disease resistance, continuous bloom cycle, and overall low-maintenance care requirements.

'Radtkopink' features fully double, cherry-pink flowers that bloom prolifically from spring until the first hard frost, offering a more classic rose look than the single-flowered original.

Uses & Benefits:

Provides a massive visual impact with its nearly non-stop display of vibrant pink double flowers. It's perfect for creating colorful hedges, mass plantings, or as a standalone specimen in mixed borders and containers, offering beauty from spring through fall.

Its dense, thorny growth can form an effective, low-growing barrier or deterrent. The extreme disease resistance and minimal pruning needs make it a time-saving choice for homeowners and commercial landscapers seeking high performance with low input.

The open-faced flowers, though double, are still accessible to pollinators like bees. Its continuous blooming provides a long-season food source for various beneficial insects, contributing to local biodiversity in a garden setting.
