Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Boltonias are vigorous perennials grown for their sprays of aster-like flowers, which appear above clean, gray-green foliage. Their vigorous nature makes them suitable for naturalizing. They are also great in the border (and for cutting), but will benefit from frequent dividing to keep in bounds, and may be cut back in late spring for more compact plants.
