Candelabra-like whorls of flowers in a formula mixture with mint scented foliage. Indispensable border flower for most soils, particularly damp sites. Height 90-100cm (30-40in).

Sow on the surface of a good free draining compost from late winter to spring. Make sure the compost is moist but not wet and seal in a polythene bag until after germination which usually takes 10-30 days at 20-25C (70-75F). Reducing the soil temperature at night aids germination.

Transplant when large enough to handle into 7.5cm (3in) pots. Later plant out 30cm (12in) apart into a rich, moist, yet well drained soil in full sun or part shade.

Cut back hard in the autumn.
