Fields of Sunflowers near the Triangle in NC

[ncdirtrider]

I'm looking for any large fields of sunflowers in bloom near Raleigh / Durham / Chapel Hill (within 25 miles). Ideally looking for a place I can take the wife for a picnic and snap some photos. She loves sunflowers, so help me score some points here. I may be showing my ignorance here, but not even sure when Sunflowers are in bloom in NC. I read somewhere that there are Summer blooming Sunflowers and Fall blooming sunflowers, so hoping it is not too late. Thanks!
