Toroweed

The Toroweed is a plant acquired in Unknown Time. It fires above and below itself, dealing large amounts of damage, but it can't attack on its own lane, making it impractical in many situations. Thankfully, it works in great harmony with defensive plants and Spikeweed/Spikerock, so with that great trinity, you can fight close to anything, although Gargantuars can't be beaten by this without extreme skills and luck.
