Clusters of cup-shaped magenta flowers open in summer, above compact rosettes of narrow, lance-shaped, hairy, gray-green leaves. This is an ideal subject for the rock garden or scree, and makes an excellent container plant for the patio, as this compact, mound-forming perennial is often grown as an annual!
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.
