Eurybia macrophylla, commonly called large-leaved aster or big-leaved aster, is noted for its large basal leaves (4-8” wide). It is sometimes planted in wooded areas more for its foliage effect than for its fall flowering which is sometimes sparse, if it doesn't get enough sunlight. This is a rhizomatous perennial that grows 2-4’ tall. It is native to woods and clearings from Nova Scotia to Minnesota south to Illinois, Ohio and North Carolina. Heart-shaped, rough, sharply-toothed, basal leaves are 4-8” wide. Ovate, stalkless upper leaves are much smaller. Stems are often purplish. Flat-topped clusters of flowers with violet to pale blue (rarely white) rays and yellow centers bloom on sticky, glandular flower stalks in August and September. Flowers are attractive to butterflies. Tender, young leaves may be cooked and eaten as greens (make certain that the plant has been identified properly).
It is best grown in moist, well-drained, sandy loams in part shade. This is a woodland species that will grow in shade, but best flowering and growth is in part shade. It spreads by rhizomes and self-seeding to form colonies in optimum growing conditions.
No known serious insect or disease problems. Powdery mildew may sometimes occur if too humid and moist.
This species has also been commonly called lumberjack toilet paper. How about that for a visual.
A nice plant for open shade gardens, native plant gardens or woodland gardens and wooded slopes.
