More information
A compact low climber suitable for small gardens. Flowers are deep cherry-red with a large white central eye and a prominent cluster of bright yellow stamens. Blooming occurs in large clusters of 3–11 flowers. Orange hips follow; their development reduces late-season bloom, so deadheading is used by those preferring more autumn flowers over fruit. Foliage is dark green and glossy. Exhibits high disease resistance. The plant is branching, densely leafed, reaching up to 3 m, and can be cut back and maintained as a shrub. Certified under ADRv 1954 .
Requires regular deadheading to maintain a tidy appearance and encourage continued bloom. The white central eye is a characteristic feature of the cultivar.
Elongated buds open to large, single bright red flowers with a white eye. The bush is upright and vigorous, reaching 2.5 m in height. Flowers nearly continuously throughout summer and autumn. Tolerates poor soils.
Flowers are blood-red with a white center; petals are slightly wavy. Foliage is dark, glossy, with a waxy appearance. Re-bloom increases when spent inflorescences are cut back. Requires full sun and does not grow in partial shade.
A low climber bearing large (11–12 cm), open, single flowers with a slight fragrance in large clusters. Blooms are bright red with a large white central spot and a cluster of bright yellow stamens. Foliage is very dark, glossy, and disease resistant. Removing developing hips promotes repeat flowering. The bush is branched, reaching 3 m.
This hybrid kordesii produces single, slightly cup-shaped flowers with wavy petals, 8–9 cm across. Each bright red bloom has a central white eye around a cluster of golden stamens; fragrance is very faint. Dortmund begins flowering in late spring with large clusters, followed by repeated waves through the season. Spent blooms develop into large, rounded, orange hips. Shoots are very spiny. Foliage is small, very glossy, dark green. Winter hardy to zone 4. With sufficient space it can be grown as a bush, though it is more commonly used as a climbing rose. In cold climates it reaches 250–300 cm on a support; in warm regions it can reach up to 10 metres. After the first flush, regular deadheading is needed; this requires time due to the prickly shoots. Without pruning, later bloom is reduced, and fruiting is increased. The lower part of the bush is bare; planting a low, fluffy shrub in front can conceal the base. Disease issues are uncommon.
