SOW
Start indoors in February or March in individual pots or modules, about 1cm deep, at around 20°C. Germination takes 1–2 weeks. In milder areas, you can also sow outdoors in April, either in pots or direct where they’re to flower.

GROW
Harden off and plant out once frosts have passed, spacing them 40–50cm apart. Keep well watered and choose a sunny, open spot. Stake tall varieties, especially if you're using them as a screen or windbreak.

ENJOY
A splash of spectacular — impressive at the back of the border or dotted through a wilder planting scheme. The unusual blooms also make striking, long-lasting cut flowers.
