Chinese fever vine
Chinese fever vine (Paederia scandens) is a climbing plant of the genus Paederia in the family Rubiaceae. The vines grow 2 to 5 m long and are much branched, rooting wherever they touch the ground. The leaves are opposite, broadly ovate, with acuminate tips, and resemble sweet potato leaves in shape. The cymes are arranged in terminal, leafy, large panicles, or are axillary, loose and few-flowered. The flowers are tubular with bright red centers, and against the green foliage they are exceptionally elegant and spectacular. The drupes are orange-red. The flowering period is August to September, and the fruit ripening period is September to October.
Native to the provinces and regions south of the Yangtze River, it was introduced by the Beijing Botanical Garden of the Chinese Academy of Sciences in the 1980s. It is highly adaptable, cold-resistant and drought-tolerant, and thrives in both sun and shade, making it an excellent climbing groundcover plant. Chinese fever vine prefers temperatures of 15°C to 30°C and can overwinter outdoors in the Beijing area. In landscaping it can be used as groundcover under trees, and its coverage is strong: any ground where Chinese fever vine grows will not produce weeds. Chinese fever vine is propagated by sowing and cuttings. Sow in early spring, in March and April, raise seedlings in a sunny cold frame, and transplant in mid-May. Cuttings can be taken at any time; select vigorous two-year-old vines, cut them into 10 to 15 cm sections, insert them in a sand bed, and keep them moist. Generally they root in 7 to 15 days, and are transplanted in autumn or the following spring. When Chinese fever vine is used as groundcover, the plant spacing is 40 x 20 cm. It can also be used for vertical greening on flower trellises. The whole plant is used as medicine and has the effects of dispelling wind, invigorating blood, relieving pain and detoxifying.
