I could not resist posting a picture of our second year seedling that is variegated and has a very rare form: it is a "fully double orchid". On orchid dahlias the petals roll the opposite way from from cactus dahlias(involute is the term and cactus dahlias are revolute) and you see the back of the petal along with the front of the petal. I saw an orchid seedling at the Federation judges seminar on Saturday and it had two rows of petals and I would call it a "partially double orchid". The form on this variegated is a bit rough but it does look exotic to me. This form is not recognized by the American Dahlia Society and the flower would be call a "Novelty Fully Double, NX.
