Heliopsis helianthoides (False Sunflower)

A genuinely adaptable, long-blooming native perennial, false sunflower self-sows readily across a wide range of soil conditions - from moist clay to dry, open sites - making it one of the most forgiving choices for naturalizing a sunny meadow planting.

Species Overview

Heliopsis helianthoides, commonly called false sunflower or oxeye, is a bushy perennial growing 3 to 6 feet tall, native to eastern and central North America. It produces masses of bright yellow, daisy-like flowers over a long bloom period. Unlike true sunflowers (Helianthus), both the ray and disc florets of false sunflower can produce viable seed.

Application

• Prairie and meadow restoration - adaptable to a wide range of soil conditions
• Naturalized plantings on dry, open sites
• Pollinator habitat - attracts hummingbirds, bees, and butterflies
• Winter interest plantings - seed heads persist and feed finches
