The Double Knockout Rose is a continually blooming rose from early spring until the first hard frost. The flowers form is a pointed oval shape with approximately 18-25 petals and blooms that are 3-3.5 inches in diameter. The shrubs will grow into a height of 3-4 ft. and a width of 2-3 ft.

The Double Knockout Rose prefers full to partial sunlight and grows best in zones 5-9. The rose is highly tolerant of extreme climate conditions, providing a wide range of geographical areas to be cultivated. This tolerance also lends itself to be planted virtually anywhere on your property.
