Planting
Choose sun or light shade with acidic, sandy or rocky soil; clay is also tolerated. Allow space for a broad clump and a permanent position for its deep roots.
Care
Avoid moving established plants, and allow young plants up to three years to flower. Cut old stems before winter if you want to prevent them breaking loose and blowing around.
Before planting: All parts are toxic if swallowed.
