- Description
-
Big-leaf Aster is a flowering, herbaceous perennial wildflower in the daisy family typically found in moist to dry forests at moderate to high elevations. At maturity, it can reach a height of 4 feet with a equal width. This shade-loving plant with large basal leaves will produce violet to pale blue flowers, with yellow centers, in early fall. The flowering, however, can be sparse and it may be more useful for its heart-shaped foliage. The species name means large leaf.
Big-leaf Aster does best in moist, well-drained, sandy or loam soils. This is a woodland species that will grow in shade, but best flowering and growth is in part shade. During the summer, stems with alternate leaves are produced, while the basal leaves wither away.
The plant will spread by means of rhizomes or self-seeding and will form colonies in optimum growing conditions. It can be useful as a ground cover.
Diseases, Insect Pests, and Other Plant Problems:
No known diseases or insect pests, Powdery mildew is possible and slugs can sometimes be a problem.
