Very rare in cultivation (try Googling it) this miniature plant from Yunnan and Sichuan makes a tidy compact mound of green foliage from which arise bright yellow flowers on short stems of just a few inches, the flowers being very much like the equally splendid Trillius farreri but having distinctive purple sepals on the reverse. It is excellent for a moist rock garden or even as a show-winner if you can keep it shaded and cool enough to do of its best.
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.
