This very distinctive species from Spain and the Pyrenees makes a tiny hard rosette of shiny green, toothed foliage with heads of disproportionately large white flowers. A diminutive, cushion-forming alpine which is amongst the earliest of rockery plants to bloom, and can be enjoyed even more closely in a trough. Best in gritty, evenly moist soil and full sun or partial shade.
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.
