Fun Facts About New England Asters

New England asters (Symphyotrichum novae-angliae) are one of the last big nectar sources for bees in the fall, bursting into shades of purple, violet, and pink just as most other blooms are fading.

The name “aster” comes from the Greek word for “star,” a nod to their bright, daisy-like flowers. In folklore, asters were believed to bring protection and patience, making them a symbol of endurance through the darker months of the year.

For pollinators, asters are a true lifeline. Honey bees, bumblebees, monarchs, and other butterflies flock to their nectar-rich blossoms in September and October, helping colonies and migrating species stock up for winter journeys. Some native solitary bees even specialize in asters, relying on them almost exclusively.

Asters also play a role in ecology: their hollow stems provide nesting habitat for small native bees through the winter, while birds enjoy their seeds into late autumn.

Planting Requirements for Sunflowers

Light:
Full sun is best for abundant blooms, though they can tolerate partial shade.

Soil:
They thrive in moist, well-drained soil but are adaptable to clay and loam. Slightly acidic to neutral soil (pH 5.5–7.5) works well.

Spacing:
Plant 18–24 inches apart. These perennials can grow 3–6 feet tall, so give them room to spread and prevent overcrowding.

Planting Time:
Plant in spring or early fall. If sowing from seed, fall planting allows natural stratification over winter for strong spring germination.

Zones:
Hardy in USDA zones 4–8, with some varieties surviving colder zones if well-mulched.

Time of Bloom:
Late summer into fall (August–October). They are one of the last big nectar plants for bees before winter, making them a cornerstone of a pollinator-friendly autumn garden.
