Cats adore the scent of this plant but beware they will frequently roll and lay on the plants in the border. The leaves can also be dried to make catnip toys for your pet.
Sow indoors, from January to April, to flower the same year, 0.5cm deep, in a tray of compost. A temperature of 15-20°C is ideal. Keep moist. Seedlings usually appear in 14-21 days. Transplant them 5cm apart, to other trays when large enough to handle. Gradually accustom young plants to outside conditions, before planting out into well-drained soil, from May to June, 30cm apart, when frosts are over. Or, sow outdoors, from April to June, to flower the following year, in a seed bed, 0.5cm deep, into finely-prepared, well-drained soil, which has already been watered. Thin seedlings to 5cm apart, before planting out to flowering position in autumn, spacing 30cm apart. Flowers from June to September.
