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.
Noteworthy CharacteristicsProduces a profusion of white, lilac, or purplish-pink rays, and yellow, disc flowers, on strong stems in late summer.
CareCut back in early summer to keep plants more compact and bushier.
PropagationSow seed in a cold frame in autumn; divide in early spring.
ProblemsAnthracnose, rust, powdery mildew, leaf spot.
