Troubleshooting

Seeds not germinating

Ensure consistent temperature (around 21°C) and adequate moisture. Check that seeds are not planted too deep and that the polythene bag is sealing in humidity.

Seedlings are weak or leggy

Provide more light and ensure they are not overcrowded. Transplant into individual pots once large enough to handle.

Plant is leaning or falling over

Ensure the plant is in a location with some shelter from strong winds. Taller varieties may benefit from staking, especially in exposed areas. Check soil drainage; waterlogged soil can weaken stems.

Few flowers produced

Confirm the plant is receiving adequate sunlight (at least partial shade). Ensure it is not planted in overly rich soil, which can promote foliage growth over flowering. Regular watering, but not overwatering, is crucial.

Setup, Compatibility & Care

Sowing Seeds:

Sow seeds from late winter to early spring. Plant them 1.5mm (1/16 in) deep in John Innes Seed Compost. Ensure the compost is moist but not waterlogged. Seal the sown tray or pot in a polythene bag until germination occurs.

Germination:

Germination typically takes 15-21 days at a consistent temperature of 21°C (70°F).

Transplanting:

Once seedlings are large enough to handle, transplant them into 7.5cm (3 in) pots. Grow them in cool conditions.

Planting Out:

Plant the young plants out into their final positions 60cm (24in) apart. Choose a location with sun or semi-shade. The soil should be ordinary, but not overly rich. Provide some shelter from strong winds.

Care:

Water regularly during dry periods, especially when the plant is establishing. Deadheading spent flowers can encourage further blooming. As a hardy perennial, it should overwinter well in most climates with minimal protection. Remove any dead foliage in late autumn or early spring.

Compatibility:

This plant is suitable for mixed borders, cottage gardens, wildlife gardens, and large containers (if provided with adequate support and drainage). Avoid planting where pets or small children might ingest the plant, due to its harmful nature when eaten.
