Hello, with the grow plant creature feat, a character have learned how to cultivate and raise plant creatures.
But do this plant creature be under the control of the character ?
" A freshly created plant creature is under no particular compulsion to obey its creator, but most regard their makers as friends and allies."
The prerequisite feat of Train Plants can also help make it a more reliable ally, but absent some other ability it won't be under your complete control.
At best it will be like a trained guard dog, not a mind controlled slave.
Think of it as your leafy child.
