Eurybia macrophylla is a woodland aster with very large leaves, as implied by its specific epithet and common name. The basal rosettes are comprised of heart-shaped leaves, with serrated edges, that are up to 8" long and 6" wide. They form a dense ground cover through early summer, at which time they begin to wither away as the flowering stalks begin to emerge. These are unbranched, up to 4" tall, with sparse heart-shaped leaves that become progressively smaller and more oval as they move up the stem. The flowers are borne in open clusters, are up to 1 1/2 inches across, and consist of pale whitish-lavender rays surrounding a yellow disk that turns deep orange, then red to brown with age. The seeds are attached to hairy tufts, and are carried by the wind.
Bigleaf aster grows under the mesic conditions found in deciduous forests. It requires moisture in the beginning of the growing season, but is adapted to the dry summer environment typical of the understory. It will tolerate rocky, sandy, or clay soil, so long as it is rich in organic matter. Flower production is best in open shade or dappled sunlight. The root system is fibrous with rhizomes. It vegetatively form colonies, but does not spread aggressively. The blooming period lasts about 1 1/2 months, during late summer and early fall. Zones 3-7
Sow immediately outdoor. Stored seeds will require cold stratification. can also be propagated from cuttings, but the easiest is to divide clumps early in the growing season.
The large, bold basal foliage is this species's defining characteristic, and once it has withered, it can be difficult to distinguish this species from other woodland asters.
