Helianthus maximiliani is a North American species of sunflower known by the common name Maximilian sunflower.
A branching perennial herb, growing from a stout rhizome and reaches heights from 0.5–3.0 m (2–10 ft). The slender, tall, erect stems and alternately-arranged leaves are covered in rough hairs.
The lance-shaped leaves are narrow, pointed, folded down the midvein, and up to 30 cm (12 in) long on large plants.
The flower heads are surrounded at the base by pointed green phyllaries which often stick straight out and curl at the tips. The center is filled with yellow tipped brown disc florets and the circumference is lined with bright yellow ray florets 2–4 cm (1–1+1⁄2 in) long.
The plant reproduces by seed and by vegetative sprouting from the rhizome.
The flower heads are attractive to insects and the fruits are eaten by birds.[citation needed] Livestock eat portions of the plant, and the seeds are eaten by various wildlife.
