Double Knock Out® is an easy-to-grow, carefree
landscape rose. Its cherry red blossoms attract attention
all summer. Blossoms are about 3-inches wide, with a classic
and beautiful double form. The petals fall off cleanly, so
you don't have to remove old blossoms. The dark-green, glossy
foliage turns a dark reddish-green in the fall. The foliage
is very healthy with resistance to blackspot and powdery mildew,
so you can enjoy your rose! The canes on this rose are winter
hardy to the crown in northern Zone 4, so this rose gets through
the winter best with a covering over the crown to ensure winter
survival in very cold climates.

What's a "bareroot" plant?
 "Bareroot"
is a term that describes how a plant is shipped to you. A
bareroot plant is not in a pot, and is usually dormant (not
actively growing). See the photo to the right that shows what
a bareroot rose looks like. The bareroot plants that we ship
to you were harvested in the fall and placed in cold storage
over the winter to keep them dormant. In the spring, we ship
the bareroot plants to our customers, from early April through
mid May.
Bareroot plants are easy to grow. We include planting instructions
with your order. When you receive your plant, take it out
of the packing material and place it in a bucket of water
so that the roots are completely covered. Let the roots soak
for 4 to 24 hours, then plant it in your garden. Full planting
instructions with photos are available on our Planting
Roses page.
