Ornamental Features

Sunny Knock Out® Rose is smothered in stunning lightly-scented yellow flowers with buttery yellow overtones at the ends of the branches from late spring to early fall. The flowers are excellent for cutting. It has attractive dark green deciduous foliage which emerges burgundy in spring. The glossy oval compound leaves are highly ornamental and turn an outstanding burgundy in the fall. The spiny brick red bark adds an interesting dimension to the landscape.

Landscape Attributes

Sunny Knock Out® Rose is a multi-stemmed deciduous shrub with a more or less rounded form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.

Planting & Growing

Sunny Knock Out® Rose will grow to be about 5 feet tall at maturity, with a spread of 4 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid.
