Getting an Upgrade

Getting an Upgrade is a Brain Buster exclusive to Sunflower Plains in Plants vs. Zombies: A New World. In this brain buster, the player can upgrade plants now (e.g. plant Sunflower on Sunflower to create a Twin Sunflower). You can't use Plant Food, Wall-nut First Aid and Shovel Boost at these levels.

If after 45 seconds, a plant isn't upgraded, it will fall asleep.

Plants
The player can only choose these plants.
