Any new Plant ideas?

I'm just curips about what you guys think that would be a cool new plant, here is my ideas.

Blueberry Bush: his smell attract other zombies and as they try to eat him, they take normal damage, it's like a Wall-nut, but can damage Zombies and attract them.

Bombing Apple: Same as the Melon-pult Plant Food effect, but have a Giant damage and she needs to recharge.

I will keep posting my ideas, post your own too! Sorry for my bad grammar, i speak portuguese. :/
