I have a story behind the flowers. They were born the last time a demon was summoned in the area. If you recall, in the history I made for the town that happened around it's founding. It's something that demon left behind. They look something like
this except as I described the stem and colors in my post, and of course the top bell flopping in the other direction and twice as big :P You can add anything else you want to the story, I just, yeah. . . .They were sprouted because of the last demon summoning. I don't think the demon itself made them sprout, more like the earth reacting to it's presence :P
