Why You’ll Love It
-
Low-maintenance: reliable in sunny, moist borders and rain garden shoulders
-
Pollinator-friendly: long late season bloom
-
Cut flower: numerous sturdy branching stems
Ideal Site & Soil
-
Sun first: full sun for best bloom and posture
-
Moisture matters: medium to wet soils; tolerates clay that is not stagnant
-
Airflow: give space to keep foliage clean late in the season
Planting Steps
-
From pots or divisions: set crown at soil line, water to settle, space 18 to 24 inches
-
From seed: fall sow or spring sow after a cold period; keep evenly moist
-
Mulch: thin, airy layer to hold moisture
Care Routine
-
Watering: steady moisture the first year; afterward, water during dry spells
-
Feeding: average soils are ideal; avoid high nitrogen
-
Pinch for height: shear by one third at 12 to 16 inches to reduce height and increase branching
-
Divide: every 2 to 3 years if centers thin

Common Mistakes
-
Too dry: short bloom and lodging
-
Too much shade: lanky stems and fewer flowers
-
Crowding: increases late season spotting
Quick Troubleshooting
-
Flopping stems: increase sun, reduce nitrogen, and pinch in late spring
-
Sparse bloom: ensure full sun and steady moisture through bud set
-
Leaf spotting: improve spacing and water at the base
