A wild type of the common cultivar; broad flower heads are white to light green and ringed with sterile, large petaled flowers that attract insect pollinators. Intolerant of drought, healthiest in edge habitats or dappled shade and moist, well drained humus. Established plants can be cut back to a couple inches above the ground in late fall-winter for vigorous and compact spring growth- plants not cut back are less compact, but lend winter texture with peeling bark.
