What I did was took all the plants and flowers and added them at the top until it gave me one for the plant I was looking for, that way you know exactly which plants to use! For instance, when I was looking for the rosaceae fern, it gave me fragrant+daisy as one of the flowers so up at the top I put to combine a fragrant fern and a daisy fern and sure enough it showed that it made a rasaceae fern. Did I explain that ok or did I confuse you more?
