Gardeners' Notes:

I live in Burr Ridge Illinois. This is a vigorous, extremely hardy and disease resistant plant. I have it planted next to other climbers that had mildew at the beginning of this year due to the unusual weather. The Night Owl Rose was completely fine. I planted this in the fall last year and had no die back this spring.

I am finding this plant is VERY UPRIGHT. I was trying to grow this horizontally on a wall trellis. This does not work. It does not form laterally shoots and only blooms at the ends of vertical cains in very large claw-like clusters. This climber seems better suited to be grown as a bush or possibly as a pillar rose.

Superb climber....super thick canes one year 3/4" thick! Prolific grape colored blooms with yellow centers...I love diseases, NO BS, no heat wilting...just you must support it...this thing has taken off in my hot Kansas Summers and -20* F winters. If it can survive and thrive can anywhere !

Very hardy, disease free. Continues to bloom throughout the summer. Thick canes need support,but it is now about 4 feet tall. A real beauty.

This is a newer rose, a deep grape-juice purple climber that I have really enjoyed growing. I am growing this rose in the center of a small triangle bed on a triangular really is a neat dark purple...eventually. Sort-of started out a bright, jarring bright plummy pinkish/purple but the color settled as the rose grew up. Disease resistant!!
