False Sunflower

landscaping idea
Heliopsis helianthoides ( Ox-Eye Sunflower )
A long lived perennial, reaching a maximum height of 6 ( rarely over 5 ) x 4 feet, that is native to eastern North America ( from northern Illinois, Michigan, Ontario to New York; south to New Mexico to Georgia. It may be used in borders or in abundance on commercial plantings. THIS VERY VALUABLE PLANT DESERVES MUCH MORE USE IN THE LANDSCAPE TRADE!
The coarsely-toothed, oval leaves are up to 6 inches in length.
The foliage is smooth and mid-green.
The golden-yellow to orange-yellow flowers, up to 4 inches across, are borne over a very long period from early summer to mid autumn if it is deadheaded.
The flowers attract hummingbirds and butterflies.
Hardy zones 2 to 9 in full sun to partial shade on moist, well drained soil. Fully established plants are moderately drought tolerant and very heat tolerant. Easy to grow except in soils that waterlog expecially during winter. Taller varieties can be cut back by half during early summer for more sturdy compact habit at bloom time. Deadheading prolongs blooming. It is not generally bothered by pests or disease other than the rare aphids or mildew. Snails and slugs may attack emerging plants however this does not occur commonly.
Propagation is from seed or division every 2 or 3 years done during spring or fall.
