Special: Doubles the damage of peas that pass through it. Fireballs deal damage to nearby zombies on impact.
Unlocked: After beating Level 3-7
Planted On: Ground, Lily Pad, Flower Pot
Torchwood is a buffing plant, meaning that it doesn’t deal any actual damage itself, but allows other plants to power up their shots by shooting over the fire and igniting the peas into fiery peas, which do double damage. The ignited peas also deal splash damage, hurting all surrounding zombies with 1 peas worth of damage when the pea hits a zombie.
Torchwood also clears some fog out on foggy levels.
Be mindful that frozen peas will thaw when passing through a Torchwood, turning the pea into a regular shot. Place Torchwood behind Wall-Nut, Tall-Nut or Pumpkins but far enough to the right that a lot of peas can pass through their fire and deal more damage.
