Impatiens sp. Sikkim
An unknown, hardy, perennial species of Impatiens that is native to the forests of Sikkim. It is superficially very similar in appearance to Impatiens stenantha though the plant, including its flowers, is larger. Forms quite a busy plant and produces the most unusual, upturned, golden yellow, orchid-like flowers with long curling spurs and red speckled throats. Leaves are dark green with scalloped edges (without the red-tinged undersides of stenantha). Flowers prolifically from May all the way to October. Moist, humus rich, well-drained soil in part to full shade in a cool position. Can be pot grown or planted in the garden. Hardiness is untested but should prove hardy to -10C (possibly more) in the ground with a winter mulch. If pot grown, it requires full protection from frosts.
