Unbelievably hardy in the UK, this attractive plant resembles an Angel Pelargonum with dainty, violet-veined, white flowers and fragrant foliage when rubbed. Flowering all summer, it creates an impressive ground cover plant for the border or rock garden.

Sowing Time: February to June or September to October. Sow seed on the surface of lightly firmed, moist seed compost in pots or trays. Cover with a fine sprinkling of compost or vermiculite. Keep at a temperature of between 15-20C (59-68F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination can take 10-30 days.

When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost, 30cm (12in) apart. For best results, provide any ordinary well-drained soil in full sun or part shade.
