Bright sprays of fragrant cruciform flowers open in early spring on this rare, miniscule and very unusual member of the cruciferae, which deserves a place in a pot in an alpine house, or in a well-drained scree or rockery. Primuloides means 'like a primula', making this another one to baffle the experts!
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.
