For best results, provide a rich, light, well-drained soil in full sun.

Sow mid January-mid March. Sow seed on the surface of lightly firmed, moist seed compost in pots or trays and lightly cover the seed with a dusting of vermiculite. Place in a propagator or warm place, and keep at a temperature of around 21-25C (70-75F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination will usually take 14-30 days.

When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost 30cm (12in) apart.

Beautiful Deep Blue Flowers 2015-08-22

I grew these this year and was not disappointed, the colour is wonderful deep blue with a bright yellow centre. Grew around six pots which I used to place among my other plants in the borders they looked stunning, and had lots of lovely comments from family and friends visiting my garden.

Stunning flowers 2014-07-27

Grew these for first time this year from seed. They are definitely on my list to grow again next year. The deep blue/purple flowers are velvety and look almost metallic. I grew them in pots mixed with pale blue laurentia, lovely combination and they grow equally well in semi-shade. Loved by the bees as well.
