Seed Packet

The Seed Packet is an item from Plants vs. Zombies.

Origin
In Plants vs. Zombies, a seed packet is gained at the end of most levels, and it allows you to use a new plant.

Use
The item is picked up and thrown, and wherever the packet lands, a plant from Plants vs. Zombies will grow. The type of plant can depend on where the packet is thrown. If it is thrown in water, then land plants will not grow, and aquatic plants will instead. In addition, mushrooms will only spawn on darker stages where fighting takes place at night.

A list of plants that can spawn can be found here.
