This very showy plant has some of the largest flowers in its genus, producing large cups of bright yellow, with a beautifully contrasting purple-brown ring inside. Coupled with short stems, this is probably the most attractive yellow sisyrinchium obtainable.
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.
