My neighbor had a sign and box out in front of her home with Free flowers on it. She wrote perennial sunflowers, 6 feet tall and 2 feet wide-clumping variety. Is there such a thing as perennial sunflowers? Obviously I grabbed some to experiment with. Please help with more information.

Yes, there are "perennial sunflowers" but they do not look like the typical annual sunflower we grow for seeds and sometimes for cutting.

You could have one of two different perennials, they are both native plants and are both rather large and gangly plants with rayed yellow flowers in late summer, they are related: Heliopsis is known as false sunflower, and Helianthus is known as sunflower. Both types like sun and may need staking. Allow them some room to spread or be prepared to divide them often.
