Suggested planting locations and garden types
- City and courtyard gardens
- Prairie planting
- Cottage and informal garden
- Cut flowers

Pruning
Deadhead to prolong flowering and to remove unattractive dead flowers; cut down to the base in late autumn and remove the cut stems, to reduce the risk of eelworm and mildew the following year

Diseases
Generally disease-free but may be susceptible to crown gall, leafy gall, fungal leaf spot, verticillium wilt, and powdery mildews
