Wild Senna

Senna hebecarpa

Wild Senna is a show-stopping perennial that adds vibrant color and lush texture to the garden. Its dense clumps of compound, green leaves provide a bold backdrop for the eye-catching clusters of bright yellow flowers that bloom in midsummer. These blooms attract bees and butterflies, providing valuable nectar and lively activity in pollinator gardens. Growing up to 6 feet tall, Wild Senna thrives in full sun and well-drained soils, making it a striking focal point in borders, meadows, and naturalistic plantings.

Maintenance Tips

  • Water regularly during the establishment period; becomes drought-tolerant once mature.
  • Deadhead spent blooms to promote further flowering and prevent self-seeding if desired.
  • Divide clumps every few years to rejuvenate growth and manage plant size.
  • Watch for pests and diseases, although it is generally resilient and low-maintenance.
