A tough, repeat-flowering shrub rose bred for impressive flower power with less fuss. Rosa 'Knock Out' produces masses of cherry-red to hot-pink blooms against deep green foliage, flowering repeatedly from spring through autumn and often continuing for longer in favourable conditions. Naturally bushy and compact, it makes an excellent choice for borders, low hedges, mass plantings or as a colourful feature in sunny gardens. Highly disease resistant and easy to maintain, it is a reliable rose for Western Cape gardens.
Why You'll Love It:
- Naturally bushy, rounded growth habit.
- Drought tolerant once established.
- Self-cleaning, so routine deadheading isn't necessary.
- Highly disease resistant compared with many traditional roses.
Plant & Care
Plant in full sun and well-drained, fertile soil. Water regularly while establishing, then deeply when needed once established. Feed in spring with a rose or balanced slow-release fertiliser. No routine deadheading is needed as the plant is self-cleaning. Prune in late winter or early spring to maintain shape and encourage vigorous new growth.
Did You Know?
Knock Out roses are self-cleaning, their faded flowers drop naturally, so you can enjoy repeat blooms without spending time deadheading every flower.
