They flower aggressively from mid-summer deep into autumn (typically August to October), filling the late-season garden gap.
The prominent central cones are exceptionally rich in nectar, making them a favorite for bees, butterflies, and hoverflies.
They require full sun (at least 6 hours daily).
These plants thrive in moisture-retentive, fertile soil. They have no tolerance for drought and prefer consistently damp, well-draining areas—even tolerating heavy clay or boggy conditions.
