An unusual member of the section Telephium, this non-spreading clump-former opens sheets of bright yellow flowers in early summer on strong stems bearing broad fleshy leaves. In the wild it is confined to the mountainous rim of north west China as far as northern Szechuan.
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.
