Great northern aster or "modest aster" is a flowering perennial plant, native to most Canadian provinces and the northern United States. It Spreads by rhizomes to form colonies in forest openings, along riverbanks or swamps, in part shade to full sun conditions. From a single stem, branches protrude out toward the top accompanied by narrow, lance-shaped leaves. Blooms appear in late summer with corymb flower clusters in resemblance to New England aster. Flowers have narrow purple ray petals with yellow to pale disk centers, attractive to butterflies.
