Wood's Blue New York Aster

Wood's Blue New York Aster (Aster novi-belgii 'Wood's Blue')

Wood's Blue New York Aster is a compact fall bloomer that brings clear blue color to borders right when the season starts to turn. Also known as Symphyotrichum novae-belgii, it forms a neat mound that fits easily at the front of sunny beds without flopping into neighboring plants. The flowers also support late-season pollinators, helping the garden feel active when many summer bloomers are winding down. If you want dependable autumn color in a smaller footprint, this selection delivers a clean, finished look with straightforward care.

Distinctive Features

This selection produces masses of small, daisy-like flowers in blue to lavender-blue tones with yellow centers, blooming from late summer into fall. The habit is compact and mounded, creating a dense dome of bloom rather than a tall, open plant. Foliage is green and forms a tidy base under the flowers, especially when plants have good sun and airflow. Mature size is typically about 12 to 18 inches tall and about 18 to 24 inches wide, making it easy to repeat in groups for stronger impact.

Growing Conditions

• Sun: Full sun for best flowering and the tightest, most compact habit.
• Soil: Well-drained soil with average to moderately rich fertility, and avoid sites that stay soggy.
• Water: Keep evenly moist through summer, and water during dry spells to support strong flowering and reduce stress.
• USDA Zones: 4 to 8.
• Airflow: Provide spacing and air circulation to help foliage stay cleaner into fall.

Ideal Uses

• Focal Point: Use a small drift as a fall focal point to create a compact mound of blue color at the front of a border.
• Front Border: Plant along sunny bed edges where the low mound stays neat and easy to maintain.
• Containers: Add to patio pots for reliable late-season color near entries and outdoor seating areas.
• Pollinator Plantings: Include in sunny beds to support bees and butterflies during late-season feeding.
• Mass Planting: Repeat in groups to build a stronger band of autumn color across the landscape.

Low Maintenance Care

• Pinching: Pinch or lightly cut back in early summer to encourage a fuller plant and more uniform flowering.
• Watering: Water during drought, especially as buds form, to support heavier bloom and better foliage quality.
• Deadheading: Shear or deadhead after peak bloom to keep the mound tidy and extend the display.
• Cleanup: Cut back to the base in late fall after frost or in early spring before new growth starts.
• Division: Divide every few years to maintain vigor and keep the clump full and productive.
