Water plants of the lake at Hogwarts.
Here is where you can ask what is this plant by describing it and hoping that someone will answer the question, or you can make up a water plant and tell us all about it, then again you can answer any of the questions.
This book is about water plants so please keep this book on subject.
Please remember to try to make the Name of the plant larger then the rest of your post.
Name: Gillyweed
It is a waterplant that lets you have gills, webbed feet and webbed hands to swim in underwater. Time limit depends on how much you eat. The more you eat, the more time you get.
