Asters bring vibrant colors to the garden during the waning days of summer and early fall, offering a delightful late-season feast for Monarch butterflies. These deer-resistant native perennials can be planted in mid-spring to extend the garden’s colorful display. For comprehensive guidance on planting, growing, and caring for asters, refer to our Asters Growing Guide.

Overview of Asters

Asters are cold-hardy perennials featuring daisy-like flowers that shine as pollinator magnets from late summer through fall. Ranging in height from 1 to 6 feet, these upright plants showcase star-shaped flower heads in hues spanning purple, white, and blue.

While over 600 aster species exist, the New England aster (Symphyotrichum novae-angliae) and the New York aster (S. novi-belgii) are the most commonly encountered in home gardens. The Aster genus was previously unified but has since been divided, with European and Asian asters falling under Aster, while North American varieties belong to Symphyotrichum.

While hybrid asters offer showy colors, opting for native “wild type” species aligns with ecological gardening principles. Despite being less flashy than cultivated varieties in some cases, native species, such as those native to your region, are generally a wise choice. Further details on recommended varieties can be found later in this guide.

Asters thrive in areas with cool, moist summers and cool nights, requiring full to partial sun. In warmer climates, they prefer protection from the hot midday sun. Well-drained, loamy soil is essential, as wet clay can lead to root rot, and dry sandy soil can cause wilting. Enhance the soil by mixing in 2 to 3 inches of compost before planting.

When to Plant Asters

The optimal time to plant young aster plants is in mid-to-late spring, once the threat of frost has subsided (check local frost dates). Alternatively, mature, potted asters can be planted when available at garden centers, typically in late summer or early fall. While asters can be grown from seed, germination may be uneven. If growing from seed, sow in the fall or start indoors during winter.

Planting Asters

When planting young aster plants in spring, space them 1 to 3 feet apart based on the variety and expected size. Fully-grown asters from late summer or early fall should be planted approximately 3 feet apart. If planting seeds, sow them 1 inch deep in pots or flats, refrigerating them for 4 to 6 weeks to simulate winter dormancy and kick-start germination. Water thoroughly and mulch around plants to maintain cool soil and prevent weeds.

Aster Flower – Growing Tips

To promote vigorous growth, add a thin layer of compost or a balanced fertilizer, along with a 2-inch layer of mulch around plants each spring. Water regularly if less than 1 inch of rain falls weekly in summer, but be cautious as asters are sensitive to moisture extremes. Watch for stress signals and adjust watering methods accordingly.

For tall varieties, stake plants to prevent them from toppling over. Prune or cut back asters by one-third in early summer to encourage bushier growth and more blooms. Asters can withstand this trimming. In winter, either cut back the foliage after it dies or leave it for off-season garden interest. Birds may also enjoy munching on the seeds.

Note that fully mature aster flowers may self-seed, but resulting asters may not replicate the parent’s color. To maintain plant vigor and flower quality, divide every 2 to 3 years in the spring.
