This most unusual and drought-tolerant plant bears fragrant yellow flowers in late spring and early summer leading to stems of curious spherical seed pods which make intriguing specimens for dried flower enthusiasts. In the garden these eventually fall apart to release the seeds.
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.
