Ryan,
I was under the impression that Scuppernongs are a named variety of Musacadines and that Musacadines can be bronze, purple, black, green and even a pink reddish color.
I just planted 24 Muscadine vines and maybe in three years I'll have a decent harvest. I planted Carlos, Noble, Higgins, Southern Home, Black Beauty, Pam, Triumph, Summit, Sugargate, Florida Fry, Delicious, Nesbitt, and Darlene. I planted two of most of them and I'm still waiting on my Alachua to arrive.
