This award-winning half-hardy perennial produces dense clusters of scented purple blooms, which sit upon sturdy stems throughout summer and into autumn. The stems rise from deep green, spiky-looking foliage and the fragrant flowers will be a magnet for pollinating insects. Ideal for providing height and interest to sunny borders and wildlife gardens. In autumn, the tubers will need to be lifted.Height: 30-60cm (1-2ft).
Sowing Information
Sow in trays, pots, etc of good seed compost in a propagator or warm place to maintain an optimum temperature of 70-75F (20-25C). Surface sow and just cover with vermiculite and exclude light. Sowing Time: February to March. After covering the seed with vermiculite give a very light spray using only half the water you would give to other seeds. Too much wet will result in poor germination.
Transplant seedlings when large enough to handle. Harden off and plant out when all risk of frost has passed 30cm (12in) apart, in full sun.
