A long-lived dwarf forming a neat tuft of bright green pointed leaves, covered in late summer and into autumn with bright magenta flowers with deeply cut petals. This is one of the most popular plants for a rockery, not least because it flowers at a time when many other rockery plants are past their best.
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.
