Radyod Rainbow Knock Out Rose

Rosa 'Radyod'

The Story

Plant Bio

The Knock Out series of roses revolutionized home gardening with their exceptional disease resistance, continuous blooming, and low-maintenance, self-cleaning nature, requiring no deadheading.

'Radyod', or Rainbow Knock Out, stands out with its single, coral-pink petals that have a bright yellow base, creating a multi-toned effect that changes as the flowers age. The new foliage emerges a deep, glossy burgundy.

Uses & Benefits:

Rainbow Knock Out provides a non-stop wave of cheerful, multi-toned flowers from spring until the first hard frost. Its compact, bushy habit makes it a versatile shrub for adding easy color to any sunny spot.

Its primary practical benefit is its 'plant it and forget it' nature. It brings the beauty of roses to gardeners who don't have the time or inclination for the intensive spraying and pruning required by traditional roses.

The single flowers are open and accessible, providing a good source of pollen for bees and other pollinating insects.

Keep It Thriving

Care Guide

Do

Provide full sun for the best disease resistance and flowering.
Water deeply at the base of the plant, especially in the morning.
Give it a hard prune in late winter/early spring for a strong flush of growth.
Mulch to keep roots cool and conserve water.

Don't

Do not plant in a shady or crowded location with poor air flow.
Avoid overhead watering, which can encourage the few diseases it might get.
Don't worry about deadheading; it's self-cleaning.
Avoid fertilizing late in the season, which can push tender growth before a frost.
