Rosa 'Double Knock Out'

'Double Knock Out' Rose

Double Knock Out is the Radtko selection, with full, double cherry-red flowers and dark foliage tinged with purple. The bushy plant brings repeated color to borders and mass plantings. It has resistance to black spot, though disease resistance is not immunity.

Give it full sun and water regularly while it establishes. Flowers repeat from spring to frost; deadheading is optional.
