Impatiens mengtszeana (Trailing Form)
A hardy, perennial species, still rare in cultivation, that is native to SW China, Sikkim, India and Thailand. Produces glossy, serrated leaves and large, yellow-orange, orchid-like flowers with curling spurs in late autumn. Rather than staying upright, this form tends to want to trail onto the ground and root at the nodes. As it flowers so late in the year, we never see the flowers before the first frosts so we like to use it as tropical-looking groundcover in the woodland garden. Height 20 cm. Moist, humus rich, well-drained soil in part to full shade in a cool, sheltered position. Proven to be completely hardy here in the ground with a winter mulch but, if pot grown, it requires full protection from frosts.
