(formerly Aster novae-angliae) is a species of flowering plant in the aster family (Asteraceae) native to central and eastern North America. Commonly known as , , or , it is a perennial, herbaceous plant usually between tall and wide. The usually deep purple flowers have up to 100 ray florets which are rarely pink or white. These surround the flower centers which are composed of just as many tiny yellow disk florets. The plant grows naturally in clumps, with several erect stems emerging from a single point. The stems are stout, hairy, and mostly unbranched. The untoothed, lance-shaped leaves clasp the stem with earlobe-like appendages, and the lower stem leaves often wither by the time of flowering. New England aster generally grows in wet environments but also has been found in dry soil or sand. The seeds and nectar of this mostly conservationally secure species, which blooms August to November, are important to a wide variety of animals, including birds, bees, and butterflies. It has been introduced to Europe, Central Asia, Hispaniola, New Zealand, and some western states and provinces of North America. The naturally-occurring hybrid species of New England aster and white heath aster (Symphyotrichum ericoides) is named Symphyotrichum × amethystinum and is commonly known as amethyst aster. It can grow where the two parents are in close proximity. There are roughly 50 cultivars of Symphyotrichum novae-angliae available, including the award-winners 'Brunswick', 'Helen Picton', and 'James Ritchie'. It has been used by indigenous Americans, such as the Cherokee, Iroquois, and Potawatomi, to heal multiple ailments. Description New England aster is a clump-forming perennial and herbaceous plant. Usually it is between tall and wide. Sometimes it can reach heights of . It is cespitose, growing in clumps with several erect stems emerging from a single point. The stems are stout and mostly unbranched. The upper stems and leaves, along with some parts of the flower heads, are covered with tiny glands on tiny stalks called "stipitate glands". Roots, stems, and leaves The roots either come from caudices or short rhizomes and are thick, appearing woody, sometimes with cormoid portions. There are usually from one to five strong, erect, hairy stems growing from the root base. These can be brown or purplish in color, and largely stipitate-glandular higher up. Symphyotrichum novae-angliae has light to dark green, thin, and often stiff alternate and simple leaves. These occur at the base, on stems,
