Maximilian Sunflower

Helianthus maximiliani

Maximilian Sunflower is a robust and beautiful native sunflower that can reach heights of 3 to 10 feet, making it an excellent choice for back borders, naturalized areas, and wildlife gardens. Its vibrant yellow flowers not only add dramatic vertical interest but also attract a wide range of pollinators. Many seeds develop after the last blooms and are devoured by seed-loving birds, particularly finches, in the fall and winter months. Thrives in full sun and well-drained soil and is highly tolerant of drought conditions, making it a sustainable choice for xeriscaping and other low-water-use landscapes.

Ecological Benefits

Maintenance Tips

  • Drought-tolerant once established; water deeply but infrequently as needed.
  • Cut back in late autumn or early spring to maintain tidy growth and encourage robust flowering.
  • Prefers well-drained soil but is adaptable to a range of soil types, including poor soils.
  • May require support in very rich soils or overly sheltered areas to prevent toppling.
  • Monitor for pests and diseases; treat as necessary to maintain health and vigor.
  • Consider leaving stalks upright post-bloom into winter for structural interest and as a resource for seed-eating birds.
