Blue Wood Aster

About this plant

Symphyotrichum cordifolium, commonly known as Blue Wood Aster, is a powerhouse of native beauty. Its heart-shaped basal leaves form an attractive groundcover, transitioning to an airy branching display adorned with a profusion of small, daisy-like flowers. These captivating blue to pale purple blossoms, often with yellow centers, create a stunning visual impact just as other garden plants begin to fade. This adaptable perennial thrives in a variety of settings, from woodland edges to more open garden beds, providing essential late-season nectar for pollinators. Its upright yet delicate habit makes it an excellent choice for naturalized areas, cottage gardens, or as a softening element in more formal landscapes. At "A Cut Above," we appreciate the Blue Wood Aster for its understated elegance and robust nature. It's a low-maintenance superstar that consistently delivers beauty and ecological value, making it a stellar addition to any discerning gardener's collection.

Installation timing

When we're in season, outside of the winter months, our goal is to get your plants installed within about two weeks. That window gives us enough time to secure your plants from our supplier and find a spot on the schedule. Throughout the process we stay in touch through notifications and your existing client portal on the main A Cut Above website, which is separate from this landscaping plants shop.

Care & maintenance

Generally low-maintenance. Cut back spent stems in late fall or early spring. May self-seed readily; deadhead if unwanted. Good air circulation can help prevent powdery mildew.

Watering suggestions

Proper watering is the single most important factor in your plant's survival after installation. Newly installed plants have a limited root system and rely on you for consistent moisture while they establish.

• First 2 weeks: Water deeply every day (or every other day in cooler, wet weather), soaking the root ball and surrounding soil.
• Weeks 3–12: Water deeply 2–3 times per week, adjusting for rain, heat, and soil drainage.
• After establishment: Water deeply about once a week during the growing season, and more often in extreme heat or drought.
• How to check: Stick a finger 2–3 inches into the soil near the roots — if it's dry, it's time to water. Deep, less-frequent watering encourages strong roots; shallow daily sprinkles do not.
• Avoid: Overwatering (soggy, waterlogged soil) is just as harmful as underwatering and can drown roots.

Watering needs vary by plant, season, soil, and exposure. Because proper watering is the customer's responsibility after installation, please make sure you understand and can follow these suggestions before ordering.

Good to know: plants and trees purchased from and installed by A Cut Above include a one-year limited warranty from the date of installation. Because plant survival depends heavily on proper watering and care after installation, losses caused by improper care, neglect, animal or chemical damage, or extreme weather are not covered, and we must be given the chance to inspect a struggling plant before it's removed or replaced. Coverage is one replacement per plant. Read our warranty info.
