Boxwood

Boxwood is a plant which takes in a Zombie nearby, making it more vulnerable to plant attacks.

Strategy
It is recommended to put it near a Wall-nut or in a Pumpkin to keep it safe. It will open up once the Zombie inside is killed. It also can't take in large Zombies, meaning it shouldn't be used on levels with them.

Plant Food Upgrade
It will create a vortex taking in all Zombies in a 3x3 area. Large Zombies that are taken in are trappen inside. Squash is recommended if many strong ones are trapped.
