A beautiful, pure white form of this popular, early flowering alpine plant. Most likely a variation of S. opp. 'Alba', the 'Blush' epithet describes the flowers turning a blush-pink as they fade. We find it slightly easier to grow than the usual 'Alba' but still slightly harder than all the pink varieties.
Only an inch or two high (3 to 5cm) so ideal in a stone trough or a special little crevice, perhaps partly shaded by a rock.
The usual rules of success apply - not hot and dry, more cool and moist.
