Aromatic Aster – Symphyotrichum Oblongifolium

Aromatic Aster – Symphyotrichum oblongifolium

Overview: Aromatic Aster, scientifically known as Symphyotrichum oblongifolium, is a hardy perennial native to North America. It is celebrated for its vibrant purple to lavender-blue flowers that bloom in late summer to fall, attracting pollinators and adding a burst of color to the garden when many other plants are winding down. The plant is also known for its aromatic foliage, which emits a pleasant fragrance when crushed.

Typical Uses:

Aromatic Aster serves various purposes in garden and landscape design:

• As a border or edging plant, providing late-season color and structure
• In mixed perennial borders, complementing other late-blooming plants
• In wildlife gardens to attract bees, butterflies, and other pollinators
• In rock gardens and native plant gardens, adding natural beauty and resilience

Establishment and Care Instructions:

Planting: Choose a site with well-drained soil and full sun to partial shade. Dig a hole twice as wide and as deep as the root ball. Place the plant in the hole, ensuring the top of the root ball is level with the soil surface. Backfill with soil and water thoroughly.

Watering: Water regularly during the first growing season to help the plant establish. Once established, Aromatic Aster is drought-tolerant and only requires supplemental watering during prolonged dry periods.

Pruning: Prune in late winter or early spring to shape the plant and encourage vigorous new growth. Deadhead spent flowers to promote continuous blooming and prevent self-seeding if desired.

Fertilizing: Apply a balanced fertilizer in spring to support healthy growth and abundant flowering. Avoid excessive fertilization, which can lead to lush foliage at the expense of blooms.

Special Features and Usage:

Aromatic Aster offers several distinctive features:

• Flowers: Masses of purple to lavender-blue, daisy-like flowers bloom from late summer to fall, providing vibrant color and attracting bees and butterflies.
• Foliage: Aromatic, lance-shaped leaves emit a pleasant fragrance when crushed, adding sensory interest to the garden.
• Drought Tolerance: Once established, Aromatic Aster is highly drought-tolerant, making it suitable for low-water landscapes.
• Pollinator Friendly: An excellent nectar source for bees, butterflies, and other pollinators, supporting garden biodiversity and ecosystem health.
• Low Maintenance: Requires minimal care once established, including occasional pruning and is resistant to most pests and diseases.
• Adaptability: Thrives in a variety of soil types, including poor and rocky soils, and is tolerant of heat and urban conditions, making it a versatile addition to many garden settings.
