Common Name:
Double Knock Out Rose
Description:
Rose ‘Double Knock Out’ is a highly popular modern shrub rose, prized for its exceptional disease resistance, continuous flowering, and low-maintenance nature. It produces abundant clusters of rich cherry-red, fully double blooms that resemble traditional roses, offering a more classic look than the original single-flowered Knock Out varieties. Flowering generously from spring through to late autumn in Melbourne, this rose thrives in full sun and well-drained soil, requiring minimal care beyond occasional pruning and feeding. Its vigorous, bushy growth habit makes it ideal for mass planting, hedging, borders, or feature planting in both formal and informal gardens. With its glossy green foliage and outstanding resilience to common rose diseases such as black spot and powdery mildew, ‘Double Knock Out’ is an excellent choice for gardeners seeking reliable colour with minimal effort.
