Board Thread:Plants vs. Zombies 2/@comment-35198094-20180608195954

Does anyone have a good, reliable strategy for Survival:Endless? My Cob Cannons and Twin Sunflowers always get eaten by Digger Zombies. Images would help greatly.

What plant do you think is the best? What is the most reliable plant to use? What is the most dangerous zombie?

Question:Why are some plants in the images of Survival Mode white? They don't have imitated versions of them.
