Botania, Cloth w/ Alum. Cover
An empty conical cylinder is place on a tray. A single dart of flower is placed into it. When the cylinder is picked up, the dart is found to be on the tray. No magic so far. The cylinder is once again placed on the tray and a single dart of flower is once again placed into the conical cylinder.
This time you do a few magical passes and when the cone is lifted, lo-and-behold, the single dart flower is transformed to a huge bouquet of very colorful flowers. The conical cylinder stands almost 10" tall.
