A plant for a warm position with shelter and rich leafy well-drained soil.
Central Nepal and south east China.
It thrives and looks superb growing up through shrubs or trellis (once started, it clings naturally by tendrils). Deciduous in cold districts where the base of the plant must be mulched heavily to protect the fleshy root system. In districts where temps drop below 1-2 deg C foliage will die off. Remove during winter.
Climbing species to 5 metre, with clusters of bright yellow teardrop-shaped flowers that dangle at intervals along the wiry stems.
D. scandens was first described by Scottish botanist David Don (1799-1841) and in 1825 whilst working as a librarian to the botanist Lambert compiled for him, Prodromus florae nepalensis, based on collections made by the botanists Francis Hamilton and Nathaniel Wallich of the Calcutta (now Kolkata) Botanic Garden. Further work was undertaken by John Hutchinson (1884-1972) when he was working at Kew as a taxominist.
