Culture
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.
Noteworthy Characteristics
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.
'Roter Stern' grows to only 12-15" tall with a low, bushy-branching habit. Features a profuse bloom of rose-red daisy-like asters (to 1.5" diameter) which typically cover the foliage mound with bloom in early fall. No staking is required. The German cultivar name of 'Roter Stern' is sometimes translated by nurseries and sold as 'Red Star'.
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.
Uses
Low-growing habit makes this aster a good plant for border fronts, large rock gardens or as an edging plant. Also effective in butterfly gardens.
