Is this a relative of a sunflower of some type, grown in dry, sandy soil?
Hi Mary,
this is related to the sunflower, but is a different genus – it is Coreopsis verticillata, the threadleaf coreopsis, a very nice native wildflower found mostly in the sandhills in South Carolina – but also a favorite cultivated plant in gardens. This is certainly the wild form, and one that is not too common in our state. Sunflower is the genus Helianthus.
Sincerely,
