Symphyotrichum Syn. Aster laeve 'Bluebird' is a standout late-season perennial that fills your garden with violet-blue, daisy-like blooms when many plants are fading. You will get an upright clump that typically reaches about 30-36 inches tall and looks great threaded through mixed borders, native plantings, and pollinator gardens.
Plant it in full sun to part shade for the best flowering and sturdy stems. Average, well-drained soil is ideal, but it is adaptable and can handle periods of dryness once established. Water regularly during the first growing season, then let the soil dry slightly between soakings to encourage a deep root system.
To keep the plant compact, you can pinch or shear stems back in late spring to early summer; this also helps reduce flopping. Deadhead if you want a tidier look, or leave spent blooms to mature for seasonal interest and seed for wildlife. Cut stems back after frost or in early spring before new growth begins.
Because it is a native-based selection, it fits naturally with ornamental grasses and other fall perennials. Expect a strong finish to the season and a steady stream of visiting bees and butterflies when the flowers open.
