Strategy
The Sunflower is the primary sun producer throughout the entire game. A typical game exhibits two full columns of Sunflowers on the leftmost column, although only one column of Sunflowers is acceptable, however not recommended. Sunflowers can either be planted on the leftmost columns for the maximum possible amount of protection or in front of offensive plants as a last line of defense.

If Catapult Zombies are present, then plant Umbrella Leaves nearby to protect the Sunflowers from their basketballs. Sunflowers that are endangered by Digger Zombies are typically protected by Pumpkins.
