The false sunflower (Heliopsis helianthoides), also known as oxeye sunflower, is an easy-growing herbaceous perennial plant that naturalizes in grasslands and at the edge of woodlands. The botanical name of Heliopsis helianthoides is a mouthful, but it basically means sunflower-like. (Helios was the Greek sun god.) And that's what these plants are. Although similar in looks, Heliopsis helianthoides is not the same as the perennial sunflower in the genus, and consequently, it's been given the common name of false sunflower.
In the garden, they're best started in the spring or fall, and they grow fairly quickly but likely won't bloom in their first year. False sunflowers feature upright clumps, triangular-shaped leaves and branching stems that allow the plants to grow in a bushy habit. The double or single daisy-like, yellow-orange flowers surround a cone-shaped, golden-brown centre disk. These plants are not invasive or toxic, so they are friendly to both your garden beds and pets.
