About Cramoisi Supérieur
As one of the old garden & heirloom roses, Cramoisi Supérieur carries the traits gardeners look for in the group — full, many-petaled blooms, often quartered or cupped. Prized for depth of fragrance and full, romantic form, the old garden roses carry a character that many modern roses cannot match.
In flower, Cramoisi Supérieur is red and fills the plant with bloom in wave after wave, carrying a light, pleasant fragrance. It is hardy across USDA zones 6-10, so it suits a wide range of gardens with the right seasonal care.
Characteristics and form
Cramoisi Supérieur makes an arching, informal shrub in most classes, typically around 3 to 6 feet tall and 3 to 5 feet wide. The blooms are full, many-petaled blooms, often quartered or cupped, medium to large in size, set against often matte green foliage. Knowing a rose's habit and mature size is the key to placing it well: give Cramoisi Supérieur room to reach its full spread without crowding its neighbors, which also keeps air moving through the plant and disease at bay.
How to grow Cramoisi Supérieur
Plant Cramoisi Supérieur where it will get at least six hours of direct sun a day in fertile, well-drained soil with good air movement around it. In cold climates, set the graft union — the swollen knob where the variety joins the rootstock — at or just below the soil line; in mild climates, keep it at soil level. Once planted, water deeply and less often to encourage deep, drought-resistant roots.
- Light: Full sun, six hours or more; morning sun is best because it dries dew early and limits disease.
- Soil: Rich and well-drained, slightly acidic at about pH 6.0–6.5. Improve heavy or sandy soil with plenty of compost before planting.
- Water: Deep, infrequent soakings at the base rather than frequent light sprinkling; more in heat, sandy soil, or containers.
- Feeding: A balanced rose fertilizer in early spring, repeated after the first flush to fuel the next.
- Pruning: Prune it in late winter to an open, outward-facing framework, then deadhead through the season.
Bloom habit: Repeat (recurrent). Cramoisi Supérieur blooms in repeated flushes from late spring until the first frost. Deadhead spent flowers to bring on the next wave.
