Where are the sprites in Harvest Moon Tree of Tranquility?

You go up to the special trees(by the way they are just trees with a single flower in front) and water the flower. It will go to a cutscene and the flower will turn into that color Sprite. ex. In Brownie Ranch there is a giant tree on a hill and there is a sign that says Alans tree, if you go up to the tree you will find a red flower in front of the tree. Water it and it will turn into the Sprite called Alan and he will give you a recipe for a rainbow.
