Adelaide Hoodless, shrub

The variety ‘Adelaide Hoodless’ is a deep pink to red–crimson floribunda shrub rose from the Parkland Series Collection. It was bred by Henry H. Marshall in Canada in 1964 and introduced by the Canadian Ornamental Plant Foundation.

Flowers are medium-sized, semi-double, borne in large clusters of about 5–15 blooms, with even larger clusters reported in autumn. Each bloom has approximately 12–16 petals and an average diameter of about 2.5 inches (around 6.3 cm). The flowers have a mild fragrance and appear in repeated flushes throughout the growing season. They are carried on long branches that may bend toward the ground under the weight of the clusters.

The plant has an arching, lax, spreading growth habit, with dark green, glossy foliage. It is a fast-growing shrub that generally requires support. Typical dimensions are about 150–185 cm in height and 150–185 cm in width.

This cultivar is very hardy, suitable for USDA zone 3a and warmer. It is reported to have high overall disease resistance, though it is susceptible to blackspot. The ploidy level is triploid.
