Sunflower, Maximillian

Sunflower, Maximilian (Helianthus maximiliani)
Also known as Prairie Sunflower or Maximilian's Sunflower

Maximilian Sunflower is a tall, late-season blooming native perennial that brings vertical drama, golden color, and ecological value to meadows, food forests, and prairie-style plantings. Towering up to 8 feet, this long-lived species blooms from late summer into fall, producing dozens of bright yellow, daisy-like flowers that provide critical nectar for monarchs, native bees, and migrating pollinators. Its deep roots help improve soil structure and sequester carbon, making it a valuable plant for regenerative landscapes and restoration projects.

Key Characteristics

• Late Blooming for Monarchs and Migrating Pollinators
  Flowering from August through October, Maximilian Sunflower is a key late-season nectar source for monarch butterflies during their fall migration. It's also a magnet for native bees, long-tongued pollinators, and beneficial insects at a time when few native plants are still blooming.

• Tall, Upright Form with Dozens of Blooms
  Each stem produces many 3-4 inch yellow flowers arranged along the upper portion of the stalk, giving a vertical, torch-like effect in the garden. These plants can reach 6-8 feet tall, creating structure and movement in meadow plantings or large borders.

• Provides Seeds for Birds and Winter Habitat for Insects
  After blooming, the plants form seed heads that attract finches and other seed-eating birds. The upright stems remain standing through winter, offering shelter for overwintering insects and habitat for native bees and beneficial predators.

• Excellent for Restoration, Silvopasture, and Soil Health
  With its deep, fibrous roots, Maximilian Sunflower helps stabilize soil, increase organic matter, and promote resilient plant communities. It's commonly used in pasture buffers, native hedgerows, prairie restorations, and pollinator strips in regenerative farm systems.

• Tough, Drought-Tolerant, and Long-Lived
  Once established, this sunflower is highly drought-tolerant, adaptable to a range of soil conditions, and extremely low-maintenance. It thrives in full sun and is ideal for low-input ecological plantings.
