This is a magnet for beneficial insects and ideal for trouble free plants that flower over a long season. The aromatic leaves can be used in cooking. Flowers the year after sowing.
Sow indoors for surest results, 0.5cm deep, in a tray of compost. A temperature of 15-20Â°C is ideal. Keep moist. Seedlings usually appear in 14-21 days. Transplant seedlings 5cm apart to other trays when large enough to handle. Gradually accustom young plants to outside conditions before planting out 30cm apart, when frosts are over. Or sow outdoors in a seed bed, 0.5cm deep, into finely prepared soil which has already been watered. Thin seedlings to 5cm apart before planting out to flowering positions in autumn, spacing 30cm apart.
