A collection from Arunachal Pradesh, NE India, with very slightly richer colouring. Distinct from many others in cultivation, this species produces 15cm tall cone-like inflorescences from August onward, from which emerge clusters of large scented, clear yellow, butterfly-like flowers with very short filaments. Generally hardy in the ground throughout most of the UK where it will be deciduous, though if pot grown under cover it remains evergreen.
