This recently discovered Chinese species has several flamboyant magenta to crimson, yellow-throated trumpet-flowers, widely flared at the mouth, which are a deeper more glowing pink than those of I. mairei, with foliage much more divided with narrow leaflets. It was originally collected at 15,000 ft elevation at the border of Yunnan, Szechuan and Tibet in October, 2000.
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.
