Boltonias are vigorous perennials grown for their sprays of white, lilac, or purplish-pink rays, and yellow disc 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 sea of aster-like flowers atop tall stems in late summer.
CareGrow in fertile, well-drained soil in full sun to partial shade.
PropagationSow seed in a cold frame in autumn; divide in early spring.
ProblemsAnthracnose, rust, powdery mildew, leaf spot.
