Rosa hybrida ‘Radtko’, commonly known as Knock Out® Double Red Rose, is a stunning and low-maintenance shrub rose that combines beauty with practicality. This deciduous shrub is part of the Knock Out® Rose family, renowned for its continuous blooms and exceptional disease resistance. It produces vibrant, double-petaled red flowers with a slight spicy fragrance, creating a bold and eye-catching display. Blooming from spring until frost, this rose offers season-long color while requiring minimal care.
