Upright, spreading 6-8 ft. Very dense; flowers hose-in-hose ⅞", vivid purplish red (57B), early. Hardier than similar clones, zones 6b-9b. Introduced into England from a Shanghai garden by Robert Fortune in 1850 or '51. Originally thought to be of Chinese origin, it is a Japanese plant and a form of the complex R. 'Obtusum'. Wisley Gardens has a plant over 60 years of age with a spread of over 15ft. Occasionally has branch sports with darker flowers deep purplish red (70A); also vivid red. See 'Coccinea'. The small flowered 'Amoenum' phase suggests relatively close relationship with R. kiusianum. Description from Galle87, p. 127. |
