Ferny foliage and graceful pure white flowers up to 4in or more in diameter make this an effective and popular, easy annual. Flowers summer to autumn. Height 3 to 4 feet.
Sow 3mm (1/8in) deep in spring at 21 -24C (70-75F) in a good seed compost. Keep soil damp but not wet, sealing in a polythene bag after sowing is helpful. Germination usually takes 5-10 days.
Plant in a sunny spot on light well drained soil. For pot plants, transplant the seedlings into 7.5cm (3in) pots, grow cool, well ventilated and give plenty of light, but shade from direct sun.
