When planting in beds and borders, mix some well-rotted organic matter with the excavated soil and firm around the plant. Choose a loam-based compost if growing in pots or containers. Water regularly to keep the soil moist but not waterlogged and mulch to retain moisture.

Fertilise lightly in spring. Protect from strong winds and provide support if needed. In autumn group container-grown plants close to a warm house wall, ensuring that containers are raised off the ground using pot feet. Cut flowers regularly for the vase to encourage even more to form.
