For those of you that aren't familiar with this item:
"This wooden staff has 10 charges. While holding it, you can use an action to expend 1 charge from the staff and cause a flower to sprout from a patch of earth or soil within 5 feet of you, or from the staff itself. Unless you choose a specific kind of flower, the staff creates a mild-scented daisy .The flower is harmless and nonmagical, and it grows or withers as a normal flower would."
But what counts as a harmless or nonmagical flower? The Powderpuff, for instance, is harmless as a flower but can be dried and powdered to make an explosive substance. The flower itself is harmless, though, right? Or is harmful and/or magical potency restricted as well?
