As Wicca is a religion focusing not on race, but on the belief structures of the individual, there is not (to my knowledge) a specific African-American Wicca. If you are asking if there is a participation by African-Americans in wicca, then the answer is yes.
When a person celebrates Wicca, they are celebrating their faith within it. Wicca is not only a religion, but it's a way of living, and most Wiccan's actually celebrate Wicca every day they are part of it.
I am a wiccan myself and looking back, wicca was created (wicca is one of the only religions not to promote the idea it is the one true religion), by a guy called Gerald Gardner. Most wiccans accept this. It is a branch of European witchcraft which probably descended from a kind of paganism. Gerald Gardner promoted a kind of freed-up witchcraft which was very popular in Europe. Ten it spread to the USA, and it became particularly popular in Canada.
