Vibrant cerise-purple antirrhinum-like flowers, clasped in lime-green bracts, cascade from delicately arching stems, that grow to 45cm (18in). This half-hardy perennial will flower from early May until cut back by frost. Non-climbing, use in baskets, containers, and window boxes.
Sow from early February to mid April in a good seed compost just covering the seed with a thin layer of compost or vermiculite. Germination takes 14-21 days at 20-24C (70-75F). Seal in a polythene bag after sowing and don't exclude light.
Water well and feed once a week through the summer. To overwinter, bring indoors to a cool, frost free place in autumn and keep just moist. For a windowsill pot plant, grow on in a 13cm (5in) pot.
