We've shown you some work with the black Schwarzwalder mini calla lily at http://www.bloomeryweddings.com/blog/BlackSchwarzwalderMiniCallaLillyBouquet.aspx. On our regular florist blog, we've highlighted some additional varieties of black mini calla lilies. There are no true black mini calla lilies; the three varieties we're displaying are actually a dark purple (Schwarzwalder), dark burgundy (Blackstar) and deep brown (Hot Chocolate).
