Rosa cymosa is a species of climbing rose native to China, where it grows from the east coast in Fujian to western Sichuan at up to 1300 m, in warm areas in scrub and gorges, and in bamboo plantations. It is sometimes called the elderflower rose as its flower formation resembles elderberry (Sambucus) flowers. Rosa cymosa has long smooth or hairy stems to 5 m, with a few, hooked thorns. Shoots and leaves are bright red when young. The leaflets are narrowly lanceolate, rounded at the base, and acuminate with a slender, curved point. Stipules are narrow and not attached to the stalk, or soon falling. The pedicels are slender. Flowers small and numerous, in a compound umbel or corymb, creamy-white, 1–1.5 cm across. The hips very small and round, around 5 mm across, and are dull or scarlet-red in color with many small seeds. Rather tender, probably best grown in a greenhouse or conservatory in frosty climates. Flowers in late May and early June.
Cyme rose has low resistance to disease and is highly prone to various leaf-spot problems. It is also susceptible to a range of insect pests, and in severe infestations most of its leaves can drop. The plant is considered difficult to care for because it needs regular watering, fertilization before flowering, and pruning after flowering and in winter. Preventive spraying might be needed, and treatments may be required if the plant becomes diseased. Cyme rose suits people who can invest time and energy in plant care, but keeping it healthy and flourishing may demand additional growing experience and effort.
How to keep Rosa Indica.
Light
Cyme rose is native to open habitats, such as sunny meadows and the edges of forests, where light is plentiful. It does best in Full Sun but can also tolerate Partial Sun, adapting well to a range of sunlight conditions.
Temperature
The cyme rose is highly adaptable to different climates, from blistering summers to cold winters. That said, it does have an optimal temperature range for growth. If temperatures rise too far, the plant can experience heat and humidity stress, which may cause it to die. In areas where temperatures approach the lower limit of its cold tolerance, it is important to use insulation measures to protect the plant.
Fertilizer
The timing of fertilizing Cyme rose is important. Apply fertilizer in early spring and continue once a month until early summer. Fertilizer promotes beautiful blooms and supplies energy during both dormant and active growth phases.
