The Knockout Rose ranges from 3 to 5 feet tall and equally wide. It
produces multiple clusters of terminal blooms, each 3 to 3.5 inches
across. These very light, fragrant flowers come in many colors and
will bloom from spring until frost. Humidity doesn’t seem to bother
the Knockout Rose, and it’s drought and cold tolerant. It’s somewhat
shade-tolerant but does need about six hours of full sun per day.
True to its low maintenance reputation, the Knock Out Rose doesn’t
require deadheading and is resistant to aphids, powdery mildew and
black spot, the scourge of rose enthusiasts. Choose a well-drained
site with good air movement. It’s perfect for grouped planting or even
hedges. The foliage turns from a lustrous green to burgundy in the
fall. Double Knockout Roses are more floriferous than regular
Knockout Roses and they raise the bar with petal counts of 18-25,
twice the number of Knockout, borne 3-6 on a stem. The additional
petals present a fuller, richer pinkish/red inflorescence that is simply
breathtaking. These blooms are about 2 ½ inches wide. But don’t let
the smaller sized blooms fool you—they make up for their size in
abundance. The new growth is a dramatic burgundy red. Knockout
and Double Knockout Roses will be a spectacular addition to every
garden. Hardiness Zones: 4 – 9

Drift - Roses “The new groundcover
roses for small gardens & containers”A
breakthrough in rose hybridizing, the

Their versatile habit fits equally well into
small home gardens, patio containers and
hanging baskets as it does when they are
planted en masse across large, open beds.
The Drifts® are winter hardy in zone 5
