Aster laevis ‘Bluebird’ is a captivating perennial known for its vibrant blooms and hardy nature, making it a standout in any garden.
‘Bluebird’ is a cultivar of Aster laevis, celebrated for its profusion of striking blue flowers. The plant features a clumping habit with upright stems and an overall graceful appearance.
Native: Symphyotrichum laeve is native to North America, commonly found in meadows, prairies, and along roadsides.
Plant Type and Habit: It is a herbaceous perennial with an upright, clumping growth habit. The plant forms a robust mound of foliage and flowers.
Size: Typically, ‘Bluebird’ reaches about 30-36 inches in height (75-90 cm) and spreads up to 24-30 inches (60-75 cm), making it a medium-sized perennial suitable for various garden locations.
Flowers: The plant produces an abundance of vibrant, daisy-like, blue flowers with yellow centers. These blooms are not only visually striking but also attract numerous pollinators. After flowering, it produces small seed heads that can be attractive in the winter garden.
Bloom Time: Flowering occurs in late summer to early fall, providing a splash of color when many other perennials are fading.
Foliage: The leaves are lance-shaped, smooth, and blue-green green, adding texture to the plant even when not in bloom. The foliage is handsome all season.
Uses: Ideal for borders, cottage gardens, butterfly gardens, and native plant gardens. It’s also an excellent choice for mass plantings to create a colorful display.
Hardiness: It is hardy in USDA zones 4-8, showing a broad adaptability to different climates.
Wildlife: The flowers attract native bees, butterflies, and other pollinators, making it an excellent choice for a wildlife-friendly garden. Smooth Aster is a host plant for the Pearl Crescent butterfly. Songbirds and small mammals eat the seeds.
Toxicity: There are no known toxicity issues for humans or animals.
Deer and Rabbit: It has some resistance to deer and rabbits, though it’s not completely immune.
Drought: Once established, Smooth Aster is moderately drought-tolerant, though it prefers consistent moisture for best growth.
Invasiveness: This cultivar is not considered invasive and typically remains well-contained within its planting area.
Benefits: Its late-season blooms provide essential support to pollinators and add vibrant color to the autumn garden. It’s also relatively low maintenance and adaptable to various garden settings.

Water: Requires moderate watering. Regular moisture is crucial, especially during dry spells. Avoid overwatering to prevent root rot.
Fertilizer: Apply a balanced, all-purpose fertilizer in early spring to encourage healthy growth. Over-fertilization can lead to leggy plants and fewer flowers.
Pruning: Deadhead spent blooms to encourage more flowering. Cut back stems after flowering or in early spring to promote new growth and a tidy appearance.
Propagation: Easily propagated by division in spring or fall. Can also be grown from seeds.
Pests and Diseases: No serious pest or disease issues.
