  1. Thanks Shellie,
    this works well, just remember you always want to reach a two-way option for the leads. So you will need to add something so that you can arrive at C.

    You could add another lead under A1 – plants with flowers, and then change the original A1 lead to B flowers with petals, B1 flowers without petals (plant 4). Under the B lead you would add C plants with purple petals (plant 3), and C1 plants with white petals (plant 2).
