We are back with another Wildflower Wednesday and this week we are highlighting a versatile native wildflower that will start blooming here in a couple of weeks!
Blue Wood Aster (Symphyotrichum cordifolium) is an essential landscape plant for late season pollinators. A host plant for Pearl Crescent and Silvery Checkerspot butterflies as well as the Wavy-Lined Emerald moth, it is easily grown from seed and often self-seeds in the landscape. Also known as Heart-Leaved Aster, distinctive heart shaped leaves form an evergreen rosette around the base of the stem and become smaller as they progress upwards. Typically growing around 3’ tall, it is a very versatile species preferring medium to medium-dry soils in partial shade, but tolerates full sun and full shade well. This species works well in open shade gardens, native plant gardens, cottage gardens, and butterfly gardens. A great choice for naturalizing in difficult dry shade sites. Blooming from the end of August through October, dainty light blue and pastel purple flowers with yellow and pink centers attract many insects, including long-tongued bees, short-tongued bees, wasps, flies, butterflies, skippers, moths, and beetles. While this and other asters are readily browsed by deer and other herbivores, they tolerate it very well and it usually only makes the plant shorter and bushier. If this effect is desired stems can be pinched back before mid-July. In addition to your fall mums, plant some native asters to complement them and feed your local pollinators!
