I am making manzanita tree centerpieces in a metal pot covered with white birch wood. I want to cover the branches with either light colored rocks or flowers, but I am in love with succulents! I can probably get a light purplish/green rosette for each pot, but what other flowers would go with them? I know it's a cactus so really, the answer would be other cacti, but what would look nice? I want to put lavendar and ivory orchids on the branches.
