Description: Wingstem (Verbesina alternifolia) is a tall, herbaceous perennial plant characterized by its distinctive winged stems and clusters of yellow flowers. It typically grows between 4 to 8 feet tall and features alternate leaves with deeply toothed margins. The stems are prominently winged, giving the plant its common name “Wingstem.” The flowers appear in late summer and early fall, arranged in flat-topped clusters at the tops of the stems. Each flower head consists of numerous small yellow disc florets surrounded by yellow ray florets. After flowering, the plant produces small, achenelike seeds attached to fluffy pappus for wind dispersal.

Known Range: Wingstem is native to eastern and central North America, ranging from eastern Canada south to Florida and as far west as Texas. It typically grows in moist woodlands, along stream banks, and in wet meadows.

Care Requirements:

  • Light: Wingstem prefers full sun to partial shade. It can tolerate some shade but may become leggy if grown in too much shade.
  • Soil: It thrives in moist, fertile, well-drained soil. However, it can tolerate a range of soil types, including clay and loam.
  • Water: While Wingstem prefers consistently moist soil, it can tolerate short periods of drought once established. Water regularly, especially during dry periods, to keep the soil evenly moist.
  • Temperature: Wingstem is hardy in USDA zones 4 to 9. It is relatively adaptable to temperature fluctuations but may suffer in prolonged periods of extreme heat or cold.
  • Fertilizer: Apply a balanced fertilizer in spring to promote healthy growth and flowering. Avoid excessive fertilization, as Wingstem can become too lush and prone to flopping.
  • Pruning: Deadhead spent flowers to prolong blooming and prevent self-seeding if desired. Cut back the stems to the ground in late fall or early spring to rejuvenate the plant and maintain its shape.
  • Pests and Diseases: Wingstem is generally resistant to pests and diseases. However, it may occasionally attract aphids or suffer from powdery mildew. Monitor for any issues and treat as necessary with organic or chemical controls.

Note: While Wingstem is a beautiful and beneficial plant for pollinators, it can spread aggressively via self-seeding in favorable conditions. Consider its potential for naturalizing before planting in garden settings.
