An adorable early spring alpine growing as slow clumps of pale, silvery-grey leaves with toothed edges. Heads of strongly perfumed violet-blue flowers in early spring.
Perfectly hardy and will do well in a stone trough or other special place on the rock garden. However, if you can offer the plant some protection - an alpine house, cold frame or even a cold porch or conservatory - you will be rewarded with the glorious perfume, unmarked flowers and silvery foliage. The leaves have a dusting of white powder (farina) that looks best when unmarked by water droplets.
Easily grown in a gritty but moisture retentive compost in a place that doesn't get too hot and dry. Some light shade will help. About 10 -15cm (4"- 6") high.
