Robusta blooms in profusion with eye-catching, single, red, 4” blooms with 5-8 petals. Her clusters are produced in abundance on a vigorous, continually blooming, upright bush with beautiful, medium-green, glossy, leathery foliage. The thick canes are covered with nail-like prickles which makes Robusta an excellent fence, hedge, or impenetrable barrier. She thrives in colder zones and needs little care to thrive and grow.
