Heliopsis helianthoides is a
Heliopsis helianthoides is a
herbaceous perennial growing 40–150 cm (16–59 in) tall. The toothed leaf blades are oval to triangular or lance-shaped and may be smooth or hairy or rough in texture. The flowers are produced from midsummer to early autumn (fall).[8] The inflorescence contains one to many composite flowerheads. Each head contains yellow ray florets which are generally 2–4 cm (3⁄4–1+1⁄2 in) long. The rays are fertile, having a small forked pistil at the base; this distinguishes them from true sunflowers.[9] At the center are many yellow to brownish disc florets. The fruit is an achene about 5 mm (0.20 in) long.[5]
In the wild, H. helianthoides may be found in wooded areas and tallgrass prairie, and sometimes along roadsides.[4]
It is a popular garden plant for moist, fertile soil in full sun. Plants grow stiff and tall, so may require staking. Several
cultivars of H. helianthoides var. scabra ("rough")[10] have gained the Royal Horticultural Society's Award of Garden Merit:[11]
- 'Benzinggold'[12]
- 'Light of Loddon'[13]
- 'Loraine Sunshine'='Helhan' [14]
- 'Sonnenglut' [15]
- 'Spitzentänzerin'[16]
- 'Waterperry Gold'[17]
The Botanical Latin species name helianthoides means “resembling sunflowers”.[18]
