Helianthus divaricatus

Helianthus divaricatus: Woodland Sunburst

Bright, unfussy, and beautifully native, Helianthus divaricatus—commonly known as Woodland Sunflower—brings cheerful yellow daisy-like blooms to part-shade gardens and naturalized plantings. Its slender stems and rough-textured, lance-shaped leaves give it a relaxed, airy character, while the sunny flowers provide a warm glow from midsummer into fall. More shade-tolerant than most sunflowers, it spreads gradually by rhizomes to form graceful colonies that support a wide range of pollinators and native insects.

Plant Characteristics:

• Height: 90–150 cm
• Spread: 60–90 cm
• Flower Colour: Bright yellow with a central disc
• Flowering Period: July to September
• Foliage: Rough, lanceolate green leaves on wiry stems
• Sunlight Requirements: Full sun to part shade
• Soil Requirements: Average, well-drained to dry soils; tolerates clay and poor soil

Uses and Benefits: Ideal for naturalized plantings, woodland edges, dry slopes, and pollinator gardens, Helianthus divaricatus thrives in tough spots and supports biodiversity with its generous nectar and pollen. It is drought tolerant once established, rarely bothered by deer, and excellent for attracting native bees and butterflies late in the season.

Companion Plants: Combine with Symphyotrichum cordifolium, Solidago 'Fireworks', and Carex pensylvanica for a dynamic native planting that balances colour, texture, and ecological value.

Care Instructions: Plant in full sun to part shade in average to dry soil. Once established, it needs little care. Cut back spent stems in late fall or early spring. May be divided every few years to manage spread in tighter spaces.

History: Native to eastern North America, Helianthus divaricatus is a valuable species in open woods and dry thickets. Its resilience and wildlife support have made it a staple in ecological restoration and native plant gardens.

Final Thoughts: With its carefree nature and glowing late-season blooms, Helianthus divaricatus brings the spirit of sunflowers into woodland and wild gardens—brightening shady places while feeding the pollinators that call them home.
