Forming low tufts or mound of small green leaves, and bearing short upright stems holding flaring violet-blue bells in late spring and early summer, this tiny dwarf gem grows well in rock crevices or walls. A true high-alpine species, it is best suited to the rock garden, alpine trough garden or gravel scree.
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.
