Tecku wrote: Really, when we look at the definition of upgradeable plant, it's a plant that you can put another plant on top of to change it. Yes, the Pea Pod is the same type of plant, but doesn't that still count? Here's the funny thing. We don't actually have any proper definition for upgradeable plant. The upgrade concept as it was in PvZ1 was only there, so we could cherry pick for either your definition or, "A plant in Plants vs. Zombies that can be turned into another plant via an upgrade.", or something else.

Well, maybe that's how the game would treat Winter Melon if it was still an upgrade plant. Maybe losing a Winter Melon would could as two. That doesn't mean it's not an upgrade plant. What do you guys think? Articles are not a place to put your opinion or speculation. Keep it on your userpage, your Blogs, or in Forum threads.

We don't know how the game would treat losing upgrade plants as because we can't actually see it in-game. Any possibilities proposed by users are therefore speculation.
