Helianthus
Helianthus or sunflowers is a genus of plants comprising about 70 species in the family Asteraceae. The genus is one of many in the Asteraceae that are known as sunflowers. Except for three species in South America, all Helianthus species are native to North America.
Description[edit | edit source]
The common name, "sunflower", typically refers to the popular annual species Helianthus annuus, or the common sunflower, whose round flower heads in combination with the ligules look like the sun. This and other species, notably Helianthus argophyllus (silverleaf sunflower), are often used in gardening and landscape design projects.
Uses[edit | edit source]
Sunflowers are cultivated for their edible seeds, which are an important source of oil for cooking and margarine. The seeds are also used in bird feeders, and the flowers can be used for decorative purposes.
Cultivation[edit | edit source]
Sunflowers thrive in full sun and prefer long, hot summers. They are remarkably tough and will grow in any kind of soil as long as it is not waterlogged.
Species[edit | edit source]
There are many species of sunflowers, including Helianthus annuus, Helianthus argophyllus, Helianthus petiolaris, and Helianthus tuberosus.
