Growing Notes
- Sow in warm soil after local frost risk has passed; avoid cold, waterlogged starts.
- Sow 5–6 mm deep, keep evenly moist through emergence and thin to 30–45 cm.
- Grow in full sun and avoid excessive nitrogen, which produces soft growth and fewer flowers.
- Shelter or discreetly support tall plants where strong wind and summer storms are common.
- Deadhead or cut stems regularly to encourage continued flowering.
