Torchwood

The Torchwood lights regular peas on fire when they pass through its flame, adding extra damage and an additional attack to enemies that are near. When planted during the Fog levels, it clears the fog around it for approximately one-and-a-quarter squares.

Although there is a flowering plant family known as Torchwood (Burseraceae [1]), which includes frankincense and myrrh, the name may also be a reference to the eponymous organization in the Doctor Who spin-off series.

Usage
Place Torchwoods in any lane in front of any plant that shoots peas to turn the peas into flaming projectiles that do double the normal damage. It also adds splash damage which deals a normal pea's damage to all nearby zombies. However, if a frozen pea passes through it, it will melt, becoming a normal pea that does normal damage. Any zombie with a shield will prevent the splash effect.

Suburban Almanac Entry
Torchwood

Torchwoods turn peas that pass through them into fireballs that deals twice as much dam age.

Special: doubles the damage of peas that pass through it. Fireballs deal damage to nearby zombies on impact

Everybody likes and respects Torchwood. They like him for his integrity, for his steadfast friendship, for his ability to greatly maximize pea damage. But Torchwood has a secret. H e can't read.

Strategy
Torchwood should only be taken on levels where you plan to use peas in order to maximize the damage potential. You only need one in each lane, but it helps to plant one before placing a second pea-shooting plant in the same lane, as the fireball area damage will be more important than firing twice as fast. Keep Torchwoods behind your regular defenses such as Wall-nuts and Tall-nuts, but far enough to the right that you can place several pea-shooting plants behind it. Plan ahead if you intend to use Snow Peas, though, and put them to the right of any Torchwoods, as frozen peas melt when they go through a Torchwood. This is usually not worth it, however, as flaming peas will defrost zombies (this includes freezing from other plants as well). Using Torchwood in conjunction with Freezing Plants is discouraged as the freezing will have little or no effect (Kernel-pult excluded).

If you are using Split Peas to defend against zombies that can bypass your defenses, such as Digger Zombies or Imps (thrown by Gargantuars), you can place a Split Pea to the right of a Torchwood so its rear-firing peas will catch fire, doing extra damage. This works best if you have two or three Split Peas to the right of a Torchwood with other pea-shooting plants behind it.

The Torchwood should not be used in Fog levels for clearing fog because it only clears the fog a small area around it. Use a Plantern or Blover instead.

The Torchwood will only affect peas, not any projectiles.

When Crazy Dave selects them, you should try to use them to their full potential.

Trivia

 * In the DS version, an Imitater Torchwood's flame is blue.
 * The Torchwood, Plantern and Blover are the only plants that can get rid of fog.
 * The Torchwood is one of the three plants that has yellow eyes, the other two being the Lily Pad and the Grave Buster.
 * Torchwood is an male plant.Torch_wood.jpg
 * The Torchwood is the only plantable tree in game modes (since the Tree of Wisdom does not appear in game modes, only appearing in Zen Garden).
 * It is strange that Torchwood and the Tree of Wisdom are treated differently in the Zen Garden and that the Torchwood grows as much as the other Bloom and Doom plants.
 * Sometimes in the level "Can You Dig It?" there is a lane where only Torchwoods and Sunflowers are seen, making sun easily collected without any zombies getting damaged.
 * In the Mini-game "It's Raining Seeds", rain doesn't extinguish the Torchwood's fire.
 * It is strange that Zombies can eat the Torchwood without getting burnt, or receive damage from it.
 * It it is the only plant with fire on it.
 * If a Pea is shot by a Peashooter Zombie towards a Torchwood, instead of lighting up, its peas hit and damage the Torchwood.
 * When you water Torchwood in the fire, it doesn't have removing fire, like the fireman.
 * It is strange that if a Peashooting plant shoots a pea through an Imitater Torchwood, the peas are burnt with yellow fire instead of white.
 * A pea that has gone through a Torchwood will not completely remove fog, even if it is ignited.
 * A Snow Pea will turn into a normal pea when shot through a Torchwood, but will turn into a flaming pea upon passing through another Torchwood.
 * All flaming peas will negate the effects freezing/slowing effects of frozen or slowed zombies respectively (including the Zombot and Gargantuar.)
 * In the Suburban Almanac, it says that Torchwood can't read.
 * Maybe it is because he would burn the paper when reading.Torchwood.gif
 * If you put a normal Torchwood next to a flipped Torchwood in the Zen Garden, they will look like thay are staring each other angriliy.
 * Torchwood is an anogram of Doctor Who.
