Heliopsis helianthoidesAlso known as:
Heliopsis helianthoides is a real show-stopper that produces an abundance of flowers that are up to 3" across, with bright yellow rays and an orange-yellow central disk. The plants are robust, bushy, with stiff, sometimes branched flowering stems that can reach a height of 5'. The leaves are dark green, serrated, with a rough texture, up to 5" long, and resemble those of blackeyed Susans.
Versatile, easy to grow, and trouble free, smooth oxeye is a prolific bloomer with a flowering period that can last up to 3 months, from early to late summer. It is not particular about soil type, and is tolerant of dry conditions. This species performs best in full-sun, but will tolerate some shade although this will lead to weak stems with a tendency to flop. The root system is fibrous, forming dense clumps over time. This species will self seed and can establish large colonies in naturalized areas. Zones 4-8
Easy to propagate from seed. A 30 day period of cold, moist stratification will improve germination rates. Cuttings made of the to 12" inches of the plant in spring will readily root. The easiest propagation method is by root division in fall.
The specific epithet, helianthoides, means sunflower-like. This is why it is sometimes also called false sunflower.
