What is the best plant in PvZ 2?

Plants vs Zombies 2 has a list of the best plants. There is a flower. There is a person named Dusk lobber. The power of cauliflower. Imitater. Shrinking violet. There is a nut called the Primal Wall-nut. I can only say that it survived several Gargantuar blasts. It costs 25 more sun and has a fast refill. There is a spring bean. It was worse in the Chinese version.
