📏

Spacing: 24 inches

📅

Days to maturity: Blooms by year 2; typically flowers August-November

🌱

Planting depth: Surface planting for seeds; transplants at soil line

Soil

Type: Well-draining loamy soil with moderate fertility

pH: 6.0-7.0

Amendments:

Compost or aged manure to improve soil structure Perlite or sand if soil drains poorly Avoid overly rich soil which encourages foliage over flowers

Growth Stages

Seedling/Establishment

4-8 weeks from planting

Young plants emerge with delicate foliage; first-year plants focus on root development rather than flowering

Keep soil consistently moist but not soggy. Provide afternoon shade in hot climates. Mulch around base to retain moisture. Avoid fertilizing heavily.

Vegetative Growth

Spring through mid-summer (April-July)

Plant produces bushy mounding growth with lance-shaped medium-green foliage; gradually increasing in size

Pinch back stem tips in early summer (before July) to encourage bushier, more compact plants with more flower buds. Water regularly during dry spells. Thin crowded stems for air circulation.

Bud Formation

Mid-summer to early fall (July-August)

Numerous flower buds form at stem tips; buds are visible as small round structures beneath outer sepals

Apply balanced or low-nitrogen fertilizer to support flowering rather than foliage. Maintain consistent moisture. Ensure good air circulation to prevent mildew.

Flowering

Late August through November (8+ weeks)

Abundant lavender-blue daisy-like flowers with golden yellow centers open in succession; plants reach peak ornamental value

Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding. Do not cut back heavily during blooming. Enjoy as cut flowers.

Dormancy/Winter Preparation

November-March

Flowering gradually diminishes as temperatures drop; foliage may brown after frost

Stop deadheading in late fall to allow some flowers to set seed (provides winter interest). Cut back stems to 4-6 inches in early spring after winter hardiness is confirmed. Do not cut back in fall.

Companion Planting

Plan your garden →

Plant with:

Sedum Coreopsis Black-eyed Susan (Rudbeckia) Goldenrod (Solidago) Russian Sage (Perovskia) Daylily (Hemerocallis) Coneflower (Echinacea) Ornamental grasses (Panicum, Miscanthus)

Avoid planting near:

Walnut trees (juglone sensitivity) Plants requiring dry soil in wet climates Very competitive aggressive spreaders like mint

Common Pests

Increase humidity and air circulation. Spray with water to dislodge. Use miticide if severe. Avoid over-fertilizing which encourages tender growth.
Ensure excellent air circulation by spacing plants adequately and pruning. Water at soil level, not foliage. Apply sulfur or neem oil spray if needed. Choose resistant cultivars.
Hand-pick beetles in early morning and drop in soapy water. Use pheromone traps away from plants. Apply neem oil or insecticidal soap if infestation is heavy.
Remove infected plants immediately. Control leafhopper populations with neem oil or insecticidal soap. Plant resistant cultivars when available.
Spray with insecticidal soap or neem oil. Introduce natural predators like ladybugs. Avoid over-fertilizing with nitrogen.

Uses

The long-lasting flowers are excellent for fresh cut flower arrangements and can be dried for long-term decorative use in dried bouquets and craft arrangements. [source]

🦋

Pollinator support and bird food

Wildlife

Autumn Majesty provides abundant nectar and pollen for bees, butterflies, and other pollinators during fall when food sources are scarce. Seeds attract goldfinches and other seed-eating birds. [source]

🎨

Floral crafts and dried arrangements

Craft

Flowers dry beautifully for use in wreaths, pressed flower art, potpourri, and other dried flower craft projects, maintaining color and form when properly dried. [source]

Harvest Tips

Cut flowers in the morning after dew dries but before heat builds. Use sharp scissors or pruners, cutting stems at an angle just above a leaf node. Cut when flowers are fully open or just beginning to open. Strip lower leaves before placing in water. Change water every 2-3 days. Cut flowers typically last 5-7 days in a vase. For dried arrangements, cut fully open flowers and hang upside down in a cool, dry location.

Fun Facts

🌱 The name 'Aster' comes from the Greek word for 'star,' referring to the star-shaped flower arrangement of the petals radiating from the central disk.
🌱 Autumn Majesty can bloom for 8+ weeks continuously, providing color well into November or even December in mild climates, making it invaluable for late-season garden color.
🌱 Asters are sometimes called 'Michaelmas daisies' in Europe because they traditionally bloom around Michaelmas (September 29), and have been cultivated for thousands of years, particularly in China and Japan.
