Boykinia Jamesii Alba
This is the rare white form, from the Rocky Mountains, this high alpine Boykinia relative has heads of five-petalled, pure white flowers, held just above a cushion of leathery, scalloped leaves in early spring. It is long-lived when happy in the rockery or alpine trough, where it prefers lean, gritty soil or scree, in full sun with a cool root run.
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.
