This wonderful rose reblooms reliably in the shade. The canes are pliable and easy to train on a pillar or arbor.

Noted by Antique Rose Emporium:
"‘Skyrocket’, known as ‘Wilhelm’ by European rose growers, is a vigorous grower with a versatile growth habit as a climber or open bush. The semi-double, red flowers are slightly scented and extremely striking by the presence of yellow stamens. This rose is often mistaken for ‘Will Scarlet’ due to the same growth habit and flower form. However, the color is slightly more cherry red. If grown as a climber, this rose will reach 10 to 12 feet."
