Codonopsis Grey-Wilsonii 'Himal Snow'

Pure white saucer-shaped flowers open on apple green stems carrying ovate, shallowly-serrated, thin textured, blue-green leaves. The slender, thread-like twining stems arise from a fleshy, deeply delving rootstock, and can climb for 2 meters or more through a shrub or a hedge, making a spectacular display as they go. This desirable plant comes from west and central Nepal in mountain shrubberies up to 3,600m.
