Boost-flower

The boost flower boosts plants around it when there's more than 5 zombies onscreen, and boosts them extra for every amount of 5 zombies onscreen (eg: 5 zombies will boost a peashooter a small amount, 10 will boost it a bit more).

Overview and Strategy
The boost flower only boosts the 8 plants around it, and if they are less than 5 zombies this plant is a bit of a waste! So it is good to use this plant when they're are lots of zombies on the level.
