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.
Seeds can be sown at any time but are best sown in winter or early spring to benefit from a cold spell in the wet compost to break their dormancy. We advise covering seeds very thinly with sand or fine grit to about the depth of the seed size. If the seeds do not come up within 6 to 12 weeks the damp seed tray can be given cold treatment in a fridge for about four weeks. They may still take very many months to appear, so please never discard the pot or tray.
