Easily grown in average, medium, well-drained soil in full sun. Prefers moist, rich soils. Good air circulation helps reduce incidence of foliar diseases. Pinching back stems several times before mid-July will help control plant height, promote bushiness and perhaps obviate the need for staking. Pinching back will also delay flowering.
Symphyotrichum novae-angliae, commonly called New England aster, is a Missouri native perennial which occurs in moist prairies, meadows, thickets, low valleys and stream banks (Steyermark) throughout the State. It is a stout, leafy plant typically growing 3-6' tall with a robust, upright habit. Features a profuse bloom of daisy-like asters (to 1.5" diameter) with purple rays and yellow centers from late summer to early fall. Rough, hairy, lance-shaped leaves (to 4" long) clasp stiff, hairy stems. Flowers are attractive to butterflies.
Genus name comes from the Greek symph meaning coming together and trich meaning hair in possible reference to the flower anthers.
Specific epithet means of New England, USA.
'Purple Dome' typically grows 18-24" tall and up to 3' wide with a low, bushy habit. Features a profuse bloom of dark purple flowers (to 1.5" across) which can entirely cover the plant with bloom from mid-August until early October. No staking is required.
No serious insect or disease problems. Some susceptibility to powdery mildew. Aster wilt can also be an occasional problem, particularly if plants are grown in poorly-drained clay soils. Taller plants may require staking or other support.
Provides color and contrast to the fall perennial border front. Mass or plant in groups. Also effective naturalized in drifts in meadows or in native or wildflower gardens.
Low habit makes this a good fall blooming plant for the border front or butterfly garden. Also useful as an edger.
