This is a small genus of herbaceous perennials native to North America and South America. Apparently, only one species (H. helianthoides) is commonly cultivated.

They may be annuals, herbaceous perennials, shrubs, trees or vines. Important members of the family include tickseed (Coreopsis,) blanket flower (Gaillardia,) sunflower (Helianthus,) goldenrod (Solidago,) marigold (Tagetes,) ironweed (Vernonia) and zinnia (Zinnia.)

Heliopsis helianthoides
ox eye sunflower
This is a herbaceous perennial that is reported to grow to five feet tall. The yellow daisies are large and produced in abundance. Plants tend to be short-lived for me (two to four years) but grow best in full sun in a well-drained, irrigated site. Reportedly, this plant grows from zone 3 to 9.
Plants are available in mail order catalogs. Plants are easily propagated by seeds and division. Reportedly, cuttings of the flower stalk (before flowering) may be rooted, also.
My plants grew to about three feet tall. They tend to disappear after a few years in dry soils, persisting a little longer where irrigated. Spring growth starts in late February or March. They flower from August to October. I had no volunteer seedlings appear.
