Long Island Native Plant Spotlight #5: New England Aster (Symphyotrichum novae-angliae)
In the next installment of our native plant series tailored specifically for Long Island gardeners, we celebrate the New England Aster (Symphyotrichum novae-angliae). Known for its lush, vibrant purple and magenta blooms, this stunning perennial stands out as a late-season superstar, bringing much-needed color and life to autumn landscapes when many other flowers have faded.
Late-Season Beauty and Ecological Excellence
As gardens transition into autumn, the New England Aster bursts into bloom, providing a final flourish of color and energy before the onset of winter. Native to the eastern United States, including Long Island, this hardy perennial flourishes from late summer through fall, with prolific daisy-like blossoms creating a rich tapestry of color and texture.
Vital Support for Pollinators
New England Asters are indispensable to pollinators, particularly in late summer and fall when nectar sources are diminishing. Bees, butterflies, moths, and beneficial insects flock to the abundant blooms for nourishment. Notably, this aster provides crucial late-season nectar resources that help pollinators prepare for winter dormancy or migration.
In particular, the New England Aster is essential for Monarch butterflies, offering much-needed nectar during their long migratory journey southward. Additionally, it's a favorite of native bees, honeybees, and an assortment of beneficial insects that contribute to maintaining garden health and biodiversity.
Growing New England Aster on Long Island
Symphyotrichum novae-angliae is ideally suited for Long Island's climate and soil conditions. Thriving in full sun to partial shade, this adaptable plant prefers moist, well-drained soils but tolerates a range of conditions, including the sandy, somewhat dry soils prevalent on Long Island.
For best results:
Plant in a sunny spot (at least 6 hours of sunlight per day).
Ensure soil has adequate drainage; amending with compost can enhance nutrient retention.
While moderately drought-tolerant, supplemental watering during prolonged dry spells promotes vibrant blooms.
To encourage fuller, bushier plants and prevent legginess, pinch back stems once or twice before mid-summer. Staking may be helpful in windy areas or with taller varieties.
Ecological and Garden Benefits
Integrating New England Aster in your garden brings multiple ecological and aesthetic benefits:
Late-season Nectar Source: Vital for late-season pollinators, providing essential food as other nectar sources diminish.
Ecosystem Balance: Attracts beneficial insects like predatory wasps and lacewings, aiding in natural pest control.
Deer Resistance: Although deer may nibble occasionally, asters are generally resistant to heavy browsing, making them reliable for Long Island gardens.
Winter Interest: Seed heads persist into winter, offering food for birds and visual interest after blooms fade.
Pairing for Beauty and Ecology
New England Aster pairs beautifully with a variety of native plants, creating visually appealing landscapes while maximizing pollinator support:
Goldenrods (Solidago species) – A perfect color complement, creating vivid contrasts.
Joe-Pye Weed (Eutrochium purpureum) – Adds height and architectural interest.
Switchgrass (Panicum virgatum) – Provides movement and texture.
Coneflower (Echinacea purpurea) – Enhances visual appeal and extended bloom periods.
These companion plants not only heighten garden aesthetics but form a cohesive ecological community that thrives on Long Island.
Practical Uses and Traditions
Beyond their ornamental value, New England Asters have historical medicinal significance. Native American tribes traditionally used asters for treating respiratory conditions. While today they're primarily enjoyed for ornamental purposes, their roots in traditional herbalism underscore the plant’s historical and cultural importance.
Landscaping Ideas
New England Asters are versatile, fitting beautifully into cottage gardens, meadow plantings, or perennial borders. Consider planting them near patios or seating areas, allowing close enjoyment of their rich color and pollinator activity. Their robust growth also makes them ideal for naturalized areas, buffering property edges or contributing vibrant visual interest along fence lines.
Caring for Your Asters
Maintenance is simple:
Divide clumps every 2-3 years in early spring to maintain vigor and manage spread.
Cut back plants in late fall or early spring to prepare for robust new growth.
