If not for losing plants or for Jester Zombie/Excavator Zombie, you can survive a level literally planting only Puff-shroom boosts. Otherwise, for regular Plant Food, it isn't really a question. Kernel-pult is very useful, and Spring Bean is straight-up OP when combined with Blover or Pirate Seas. So my list is:

1. Spring Bean

2. Kernel-pult

3. Infi-nut
