Originating in the mountainous regions of Europe, this vigorous and hardy perennial has been very successfully bred and selected from the wild form. Its lovely flower spikes of deep violet-blue blooms make a great choice for the front of borders and will serve as excellent ground cover as well.
Often known as 'self heal' - the foliage was used to stop bleeding in medieval times - this charming plant will attract bees and butterflies to the garden.
Sow January to April. Sow seed on the surface of lightly firmed, moist seed compost in pots or trays. Lightly cover the seed with a fine sprinkling of vermiculite. Place in a propagator or warm place, and keep at a temperature of between 18-21C (65-70F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination will usually take 14-21 days.
When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays. Gradually acclimatise to outdoor conditions for a few weeks before planting out after all risk of frost, 30cm (12in) apart, or plant into containers.
