Heliopsis Helianthoides- Oxeye Sunflower
Hardy Planting Zone: Oxeye sunflowers can tolerate light shade; they do not grow as high in dense shade. Oxeye sunflowers can thrive in challenging environments where the soil has eroded, or the land is arid, such as prairies, although oxeye sunflowers do need extra water in drought zones. They are native to the northeastern and central United States. Oxeye sunflowers can be found in moist areas, open woodlands and woodland edges, and valleys.
Mature Height: 3 to 4 feet; some oxeye sunflowers can grow as high as 6 feet. Soil Requirements: Oxeye sunflowers tolerate rocky, tough soil, including clay soil, but thrive in moist, dense, well-drained soils.
Growing Speed: Oxeye sunflowers are short-lived perennial flowers. They grow and bloom throughout the summer months and into the first frost. Late July and August are their peak seasons.
Characteristics: Oxeye sunflowers are a spreading, branched plant. They are closely related to true sunflowers and daisies. Oxeye sunflowers bloom earlier in the season than true sunflowers. They attract butterflies and do not have severe problems with other insects or plant diseases. They are somewhat susceptible to aphids. Oxeye sunflowers will self-sow in open soil but can also divide in the spring.
Appearance: Oxeye sunflowers are sometimes called the false sunflower because it looks like a real sunflower but is not one. Oxeye sunflowers form clumps and have tall, stiff stems. Full bloom is 2-3 inches in diameter with rusty orange leaves and a light brown center - hence their name. Oxeye sunflowers have opposite arrowhead-shaped leaves on their stalks and small paired leaves at the base of the leaf stalk.
