New England aster (Symphyotrichum novae-angliae) is one of the showiest North American native plants in the fall garden. Vibrant purple petals and contrasting yellow to orange centers are visually attractive to both gardeners and pollinators.

With pollinators needing a continuous supply of pollen and nectar throughout the growing season, New England aster fills an important niche in late September and October, as few other plants flower this late in the season. Use it in informal prairie plantings, butterfly or pollinator gardens, rain gardens or traditional perennial borders, or at pond edges, where fall color is needed.

Distinguishing traits. New England aster grows quietly in the background throughout the summer, then begins to shine as other perennials look worn out and tattered from the growing season; with tightly clustered, clasping leaves, upright flower stalks and clusters of purple flowers, this native perennial is a star of the fall garden. Holm Design & Consulting LLC How to use it. New England aster performs best in moist sites, including rain gardens, ditches, pond or wetland edges, or other low-lying sites where water collects after a rain fall. Drier sites are tolerated if the soil has a higher clay content. This plant’s preference for moist sites is more apparent in the upper Midwest. As one travels eastward around the southern Great Lakes area, New England aster commonly grows alongside Canada goldenrod (Solidago canadensis) in old, dry fields.

New England aster does well in traditional perennial borders when sited near the back of the bed to accommodate its tall stature. Holm Design & Consulting LLC Planting notes. In droughty situations, the lower foliage can brown out in midsummer. Gardeners often plant a perennial in front of the aster to hide this potentially unsightly feature. If this is a recurring problem, consider transplanting your plants to a moister site. Gardeners who do not like the plant’s height can cut back the flower stalks in midsummer (July) to keep the plant more compact.

In rich, loam or clay-loam soils, New England aster has the potential to reseed prolifically. If this is a concern, you can cut off and bag the flower heads to reduce seed dispersal. Normally it is nice to leave seeds for wildlife to consume, but the seeds on this aster are rarely sought after by birds or other wildlife.

New England aster is a staple for pollinators in fall, when few other plants provide nectar and pollen. Migrating butterflies, such as monarchs, depend on this valuable nectar source as they prepare for their southward journey in the fall. The open, flat flowers provide an easy platform for perching on while gathering nectar — a floral feature preferred by butterflies. The shallow disk florets in the center of the flower allow pollinators access to nectar whether they have a short or long tongue.
