Landscape uses
Use in perennial borders, cottage gardens, pollinator gardens, rock gardens, and naturalized plantings. The seed pods are also useful in dried arrangements.
Planting schedule
Plant bare roots in spring after the danger of hard frost has passed, or in fall where winters are mild.
How to plant
Plant the bare root with the crown at soil level and the roots spread naturally. Space plants about 18 to 24 inches apart. Water thoroughly after planting and mulch lightly, keeping mulch away from the crown.
Care guide
Water regularly while establishing, then provide moderate moisture. Remove weeds, apply a light layer of compost or balanced fertilizer in spring, and avoid persistently wet soil.
Pruning
Remove spent flower stems to limit self-seeding or leave them to develop ornamental seed pods. Cut back dead foliage in late fall or early spring.
Common problems
Root rot can occur in poorly drained or consistently wet soil. Slugs and snails may occasionally feed on young foliage.
Seasonal care
- Spring: Plant bare roots after hard frost, keep newly planted divisions evenly moist, and remove winter-damaged foliage.
- Summer: Water during extended dry periods, enjoy the flowers, and leave selected stems for developing seed pods.
- Fall: Collect seed pods for arrangements, remove declining foliage after frost, and maintain good drainage.
- Winter: Keep the planting area well drained and avoid heavy mulch over the crown.
