More information
Circus exists in several forms in cultivation; the cultivar shows minor mutations (sports). The original, most widespread form bears orange blooms with reddish edges and a pinkish cast at opening, later fading to yellow. Flowers are produced in dense clusters, rounded, with wavy petals, in clusters of 3–11. Foliage is small, dark, and disease-resistant, and the plant has large thorns. The shrub is low and dense, and it tolerates both rain and sun well.
Two forms are encountered. The original is a compact bush with glossy dark foliage and large clusters of blooms with wavy petals, initially creamy yellow, then pink, and finally coral-red. The second form is a more elongated bush, sometimes bare at the base, with less colorful flowers that often do not open fully.
Flowering is very abundant. The cultivar has been used in the development of many varieties. It blooms in clusters with color shifting from yellow-pink, salmon, and orange to red depending on climatic conditions. Used as a bedding rose.
Buds are pointed and elongated. Flowers have a copper-yellow center and salmon-pink toward the petal edges, with an increasing red tone as they open; cupped to open; large (7–8 cm); double (37–40 petals); slightly fragrant; borne in inflorescences of 3–10 on 50–60 cm pedicels. Leaves are plentiful, dark green with a bronze sheen, leathery and glossy. Bushes reach 80 cm, erect and dense. Blooming is abundant. Winter-hardy. Suitable for groups and borders. Awards: Geneva, Gold Medal, 1955; National Society of Rose Growers of Great Britain, Gold Medal, 1955; All-America Rose Selections winner, 1956. Int. GBS, 1964.
