Top aster varieties for your garden
Gardening enthusiasts and experts alike have their favorite aster varieties. Here are some top picks that are sure to enhance your garden :
1. New England Aster (Symphyotrichum novae-angliae) : This North American native is prized for its large, colorful blooms in shades of purple, pink, and white. Some notable cultivars include :

These asters are not only beautiful but also serve as excellent cut-and-come-again flowers, providing continuous blooms throughout the season.
Growing and caring for asters
To ensure your asters thrive and produce abundant blooms, follow these expert tips :
Soil and sunlight requirements : Most asters prefer well-draining, fertile soil and full sun exposure. However, some varieties, like the White Wood Aster (Eurybia divaricata), can tolerate partial shade.
Watering : Keep the soil consistently moist, especially during dry spells. Proper watering helps prevent powdery mildew, a common issue with some aster varieties.
Pruning and support : Taller varieties may require staking to prevent them from flopping over. Pinch back the growing tips in late spring to encourage bushier growth and more blooms.
Division : To maintain vigor and prevent overcrowding, divide asters every 2-4 years in spring.
| Aster Variety | Sunlight Needs | Soil Preference | Bloom Time |
|---|---|---|---|
| New England Aster | Full sun | Moist, well-draining | Late summer to fall |
| New York Aster | Full sun to partial shade | Well-draining, fertile | Late summer to fall |
| Frikart’s Aster | Full sun | Well-draining, fertile | Mid-summer to fall |
By providing the right growing conditions, you can ensure your asters thrive and become a stunning focal point in your garden. Consider growing hummingbird mint alongside your asters for a pollinator-friendly garden that buzzes with life.
Asters for specific garden styles and purposes
Asters are versatile plants that can be incorporated into various garden styles and serve multiple purposes. Here are some expert recommendations for using asters in different garden settings :
Wildflower gardens : For a naturalistic look, consider planting native aster species like the Aromatic Aster (Symphyotrichum oblongifolius). These plants are well-adapted to local conditions and provide food for native wildlife.
Cottage gardens : The New York Aster and New England Aster varieties work beautifully in cottage-style gardens, adding a romantic touch with their daisy-like blooms.
Rock gardens : Dwarf varieties like the Alpine Aster (Aster alpinus) are perfect for rock gardens or the front of borders, adding pops of color without overwhelming smaller spaces.
Shade gardens : The White Wood Aster (Eurybia divaricata) is an excellent choice for shaded areas, providing delicate white blooms in late summer and fall.
Cut flower gardens : Many aster varieties make excellent cut flowers. The Calico Aster (Symphyotrichum lateriflorum) is particularly prized for its cloud-like sprays of tiny flowers that add texture to bouquets.
Incorporating asters into your garden not only adds visual interest but also supports local ecosystems. These plants are excellent for attracting bees and butterflies, making them a valuable addition to any pollinator-friendly garden.
Innovative ways to showcase asters in your landscape
To make the most of these stunning perennials, consider these creative ideas for showcasing asters in your garden :
Mass plantings : Create a sea of color by planting large drifts of a single aster variety. This approach is particularly effective with shorter cultivars like the ‘Professor Anton Kippenberg’ New York Aster.
Companion planting : Pair asters with other late-blooming perennials like Sedum, Rudbeckia, and ornamental grasses for a dynamic fall display. The contrasting textures and forms create visual interest and extend the blooming season.
Container gardens : Dwarf aster varieties are excellent for container plantings. Try the compact Showmakers Series of New York Asters for colorful patio or balcony displays.
Naturalistic plantings : Embrace the new perennial movement by incorporating asters into prairie-style or meadow gardens. This approach creates a more relaxed, ecological landscape that requires less maintenance.
Focal points : Use taller aster varieties like the New England Aster ‘Harrington’s Pink’ as striking vertical elements in the back of borders or as standalone specimens in island beds.
By thoughtfully integrating asters into your landscape design, you can create a garden that not only looks beautiful but also supports local wildlife and reflects the natural beauty of your region.
In conclusion, asters are indispensable perennials that offer gardeners a wide range of options for adding late-season color and interest to their landscapes. From compact rock garden varieties to tall, stately border plants, there’s an aster for every garden style and purpose. By selecting the right varieties and providing proper care, you can enjoy these cheerful daisy-like blooms year after year, creating a vibrant and ecologically valuable garden space.
