Growing Tips 

Planting Time:
Spring (August—October), once frost risk has passed and soil warms up.

Position:
Full sun with good air circulation. Great for borders, pots, and pollinator-friendly gardens.

Soil:
Loose, fertile soil enriched with compost. Ensure good drainage to prevent rot.

Watering:
Keep evenly moist, especially during flowering. Avoid overhead watering to reduce fungal issues.

Feeding:
Apply a balanced or potassium-rich liquid fertiliser every 2—3 weeks once established.

Maintenance:
Deadhead spent blooms to promote continual flowering. In cooler zones, lift and store tubers over winter.

Overwintering:
In frost-free areas, leave tubers in-ground with mulch protection. Elsewhere, lift and store dry.
