Helianthus maximiliani (Maximilian Sunflower)

Helianthus maximiliani, commonly known as Maximilian Sunflower, is a tall, clump-forming perennial native to North America. It features bright yellow, daisy-like flowers with dark brown central disks that bloom profusely along tall, upright stems. The plant's narrow, lance-shaped, gray-green leaves are covered in fine hairs, giving it a textured, silvery appearance. This hardy sunflower is ideal for naturalistic plantings, meadows, and pollinator-friendly gardens.

Helianthus maximiliani thrives in well-drained soils and is highly drought-tolerant once established, making it an excellent choice for xeriscaping or low-maintenance gardens. It attracts pollinators like bees and butterflies and provides seeds for birds in the fall. The plant is deer-resistant and thrives in a variety of conditions, including poor soils. Its tall, striking form pairs well with ornamental grasses and other late-season perennials like asters, goldenrods, and rudbeckias. For best results, occasional thinning or cutting back in early summer can help manage height and encourage bushier growth.
