I would love to see this as a skill, perhaps following Herbalism 2. You would need a to buy a vase, and there would be recipes for different arrangements. Some arrangements would attract butterflies or fireflies, some would make lovely home decor, and some would have mood altering abilities. I would even like one that you can put on your own tombstone to erase it (I am always so embarrassed to see a tombstone with my name on it).
