Description

An exquisite plant, producing a long succession of perfumed bright yellow flowers on a compact dome from Christmas onwards into late spring. This variety is especially desirable as it will gently self-seed into cracks and pathways never becoming a nuisance.

Sowing Advice

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.
