Kingdom of Knuffel

You can see in the dark

You have a perfect sense of direction, you always know the way even through the largest forest.

You can enhance or hinder plant growth, and even control type of growth.

So in the winter you can help the roots reach down further and anchor plants to help prevent mudslides, and strengthen branches to help prevent them from breaking under the weight of snow and ice. You can encourage blossoms in the spring and fruit growth in the fall and foliage growth whenever the plant requires it.
You can also look at a plant overburdened by fruit and inhibit it so that its strength can keep up with its ambitions...

And you always always always win the rose contests. :)
