This spectacular long flowering species has rich, ruby red stems flanked in whorls of lipped, candy pink flowers with serrated, deep green foliage for the perfect contrast. Although it looks extremely exotic it is in fact completely hardy, dying down and then re-appearing again reliably each spring.
February to June or September to October. Sow seed in pots or trays of moist seed compost and cover with a very fine sprinkling of compost or vermiculite. Keep at a temperature of between 15-20C (59-68F). After sowing, do not exclude light as this helps germination. Germination can take 1-4 months. Transplant seedlings into 7.5cm (3in) pots or trays. Plant out after all risk of frost, 60cm (24in) apart. For best results, provide any ordinary, well-drained soil in full sun.
