Sunflower Types

Sunflower Types and Varieties

Sunflowers belong to the genus Helianthus, which contains over 80 different species. The sunflower that most people refer to is Helianthus annuus, meaning annual sunflower. 38 species of Helianthus are perennial, which grow back every year on their own. I’ll first, touch lightly on those perennial sunflowers, which are cousins to the fast growing sunflowers that we all love so much. Further down the page, you’ll find many varieties of annual sunflowers.

Helianthus maximillianii

This is a perennial sunflower that has many 3″ flower heads and grows up to 10 feet tall. It can have the tendency to be invasive if you do not dead head the blooms before they go to seed. I have this planted in a grassy field and it has not produced other plants. Maximillian Sunflower, also sometimes called Prairie Sunflower, makes a big impact if you have the room for it.

Helianthus angustifolius

Commonly referred to as Swamp Sunflower and mostly found in the eastern United States. Swamp Sunflower, as it name implies, likes moist conditions. Has long narrow leaves, it is often seen growing near creek beds. Can grow in dry soil but will not be as tall.

Helianthus divaricatus
