Stick it in the plant's pooper.

When she finds her plants dead she's gonna be sick and turn [i]green[/i]

You want to kill this plant? Alright. What you need to do is set up a party. Not just any party. A piñata party. Now, this isn't your average school occasion, so you'll need to bribe the teacher's favorite student in order for them to ask about having one in order to increase morale. Perhaps they could spin a sob story about how they missed their birthday. Anyway, if this odd request succeeds, the event will be scheduled on a future date. This is the margin of time in which you must assemble a small group of like-minded individuals who will help you coordinate your plan. Make sure there will be snacks, or else this plan will surely fall through. Your group will be in charge of bringing all the snacks and setting up the table where these snacks will be placed. So, skip ahead to the big day. The piñata is set up in the middle of the room, and everyone is ready. However, the snacks are still being set up. You suggest that there isn't enough room for the tables to be in the classroom, so you move them out to the hallway. You suggest that your teacher should give the first swings due to their kindness of setting up the event. You the blindfold on her, and once the blindfold is on, this is when you declare the snack table is ready for everyone to go get their snacks. Most people will leave the room to go get their snacks, but your group will remain. Once the last person leaves, one of you closes the door behind the group. Hopefully you can find a way to lock them out. Now you move on to the piñata. You tell your teacher there's a slight problem with how it's set up, while keeping her blindfold on, and that's when the most important part of your plan commences. Where the piñata once was, you string up her plants. You have to be very quick with these steps, as there is a group of people that will return from getting their snacks at any moment who will alert the teacher, and she can't suspect anything is wrong. Once the plants are in place, you point her in the right direction, and you get her swinging. This is where your teacher will destroy the very plants she has loved so dearly.

Also, a quick side note: Destruction of personal property is illegal and posting about it (illegal activities) is a bannable offense. Just a heads up.
