Easily grown in average, dry to medium, well-drained soils in full sun. Good soil drainage is essential. Wet soils in winter can be fatal. Tolerates some light shade, particularly in hot summer climates or when plants are being grown in dryish soils. Remove spent flower heads to promote additional bloom. Divide clumps as needed (every 2-3 years) to maintain vigor. Plants are somewhat short-lived. Consider cutting stems back to basal leaves after flowering to preserve plant energies and perhaps prolong plant life.
