Several scrapped ideas for plants can be found in an early build from 2008, and almost all of them made it over to different games in different ways:

• The Beehive, which would have shot bees at Balloon Zombies, was repurposed as the Beeshooter in Plants vs. Zombies: Adventures, a now-defunct Facebook game.
• Iceberg Lettuce, which was seemingly a freezing version of Lettuce-pult like Snow Pea and Winter Melon, had its name repurposed into a plant in Plants vs. Zombies 2, which froze zombies that stepped on it for a few seconds.
• Time Stopper was repurposed as Thyme Warp, which instead of refreshing all plants would send all zombies back to the start of the lawn at full health.
• Yampoline was repurposed as Spring Bean, but would send zombies backward instead of forward.

Not all were repurposed, as Tuber, Cherry Hover-Bomb and Duplicator Cycler were never reused, most likely due to their redundancy.
