Symphyotrichum shortii

Symphyotrichum shortii: Short's Aster

A durable and graceful native for dry woodland edges, Symphyotrichum shortii produces a profusion of starry, pale bluish-lavender flowers with golden centres from early to mid-autumn. Its upright stems carry toothed, lance-shaped foliage that transitions to soft hues in fall. Adaptable and unfussy, this clump-forming aster is especially valued for its ability to thrive in challenging dry shade while supporting late-season pollinators.

Plant Characteristics:

• Height: 60–100 cm
• Spread: 50–70 cm
• Flower Colour: Pale lavender-blue with yellow centres
• Flowering Period: September to October
• Foliage: Green, lance-shaped leaves with coarse edges
• Sunlight Requirements: Full sun to part shade
• Soil Requirements: Average to dry, well-drained soils; tolerates clay and rocky substrates

Uses and Benefits: Perfect for naturalizing along woodland borders, slopes, or open shade gardens, where it delivers structure, colour, and pollinator value well into fall. Its tolerance for drought and less-than-ideal soils makes it a smart choice for tough garden spots, particularly under trees or in native plantings where wildlife support is a priority.

Companion Plants: Pair with Heuchera 'Autumn Bride', Carex 'Blue Zinger', and Dryopteris 'Male Fern' for a textured, shade-tolerant combination that balances seasonal interest and resilient foliage.

Care Instructions: Plant in full sun to part shade with well-drained soil. Once established, it requires little supplemental water. Cut stems back after flowering to prevent excessive self-seeding. Divide every 3–4 years to maintain vigour and manage spread.

History: Native to eastern and central North America, Symphyotrichum shortii is a dependable species aster long appreciated for its drought tolerance, naturalistic charm, and ecological value. It is named in honour of botanist Charles Wilkins Short.

Final Thoughts: With its soft lavender blooms and adaptability to dry, shaded spaces, Short’s Aster quietly extends the garden’s life into autumn—where colour meets resilience and habitat support.
