Spikeweed


 * For the plant and ability in Plants vs. Zombies: Garden Warfare, see Spikeweed (Plants vs. Zombies: Garden Warfare)

Spikeweed is an Area of Effect plant that attacks, dealing normal damage to all zombies that walk on it. It does five peas' worth of damage in the time it takes any normal speed zombie to pass over it (faster zombies, such as the Football Zombie, can take as little as two peas worth of damage). It will also pop the tires of the first vehicle zombie that drives over it. Since the Spikeweed attacks from below, it can bypass shields.

Plants vs. Zombies
Spikeweed is unlocked after the player beats Level 3-6. After that, the player can use Spikeweeds against the Zombonis in the next few levels. They can only be planted on the ground (not on Lily Pads or Flower Pots, so that makes them useless for Roof levels). A Spikeweed can be upgraded to Spikerock after purchasing the Spikerock seed packet.

Plants vs. Zombies 2: It's About Time
Spikeweed is unlocked after beating Pirate Seas - Day 6. It works almost same as what it does in the first game, but does less damage at a faster rate, still doing the same amount of damage overall. There are some new zombies that can be popped by Spikeweed such as Barrel Roller Zombie and the Pianist Zombie. Unlike the first game, it cannot be upgraded to the Spikerock.

Plant Food Upgrade
Its Plant Food ability is that it fills the row with other spikes poking up from the ground and pulls zombies to the Spikeweed for 4.5 seconds. The secondary spikes can destroy rolling items and attack zombies being drawn towards the Spikeweed. If this occurs when the Spikeweed is in a minecart, the Spikeweed may not be moved.

Level upgrade: (Chinese version only)
Level 2: When it kills 15 zombies, it will become twice as powerful until it is eaten, attack +50%.

Level 3: When it kills 5 zombies instead of 15, it will become twice as powerful until it is eaten, attack +50%. (total +100%=2x).

Costumed (Chinese version only)
Plant Food ability can hit zombies on a jumping animation (maybe does more damage) and does a small stun.

Spikeweeds pop tires and hurt any zombies that step on them.

Damage: normal

Range: all zombies that walk over it

Special: can't be eaten by zombies

Hockey is Spikeweed's obsession. He's got box seat season tickets. He keeps close track of his favorite players. And he consistently cleans up in the office hockey pool. Just one problem: he's terrified of pucks.

Although Spikeweed grew up on the seedy side of town, his acupuncture business has been blooming.

Standard Levels
Plant Spikeweeds in front of Wall-nuts, Tall-nuts, or Pumpkins. Most zombies cannot harm it, and will be continuously damaged as they try to eat the defensive wall. Spikeweed is especially important for levels with Zombonis (especially in Bobsled Bonanza), and placing the Spikeweed on the first row will prevent the Zomboni from laying any ice at all (preventing the appearance of the Zombie Bobsled Team). Note that Gargantuars, Giga-gargantuars, and Jack-in-the-Box Zombies can destroy Spikeweeds in the same way as they can any other plant.

Hokey Pokey
Try to lay down either a row of three Spikeweeds or one Spikeweed in front of a Wall-nut to kill the zombies. Timing can be everything, so if you see a Wall-nut, go ahead and break a few vases on the right hand side to see if a Wall-nut will be needed there. If no zombies appear closer than the fourth row from the left, put the Wall-nut on a different row, and lay down Spikeweed instead. Buckethead Zombies are the exception to this, as you cannot kill them with just Spikeweed - make sure to have a Wall-nut in place or use a Squash to kill them.

Plants vs. Zombies

 * Somehow, Spikeweeds and Spikerocks damage helmets from headwear zombies, despite them hitting their feet.
 * The Spikeweed and its upgrade are the only plants that instantly kill some zombies but only damage others.
 * In the reanim folder, the Spikeweed's name is Caltrop. This may be because the Spikeweed functions like caltrops; it hurts anyone that steps on it and pops tires.
 * Even though Spikeweeds cannot be planted in Flower Pots during Roof levels, Spikeweeds are always in Flower Pots in the Zen Garden. This is probably because a Spikeweed would be useless in a Flower Pot, as zombies would not walk over it, but they do not need to attack any zombies in the Zen Garden. The Spikeweed is actually too wide for its Flower Pot, and sticks out over the sides, like an armed Potato Mine.
 * Spikeweeds and Spikerocks have a faster attack rate than other plants.
 * When a Spikeweed is planted in one of the two bottom right squares on Pool and Fog Levels, it will be higher up than other Spikeweeds.
 * The Jack-in-the-Box Zombie, the Zomboni, the Catapult Zombie, the Bungee Zombie, the Gargantuar, the Giga-gargantuar, and the Jalapeno Zombie are the only zombies that can destroy Spikeweeds and Spikerocks.
 * Alone, it takes two Spikeweeds to destroy a regular Zombie.
 * When a Zomboni hits a Spikeweed and then a Squash tries to squash it, the Zomboni will not explode when the Squash squashes it. That is because the Zomboni is already killed after hitting the Spikeweed, so the Squash will not affect it.
 * It is unknown how the Spikeweed can make the Zomboni's ice machine or the Catapult Zombie's catapult machine explode by just popping the tires, although the Spikeweed may degrade their health to zero. If they do not explode, it would not make sense, since the zombies cannot escape and leave the vehicle on the lawn, the spikes of the Spikeweed and Spikerock may have damaged parts other than the tires, causing the vehicle to explode.
 * Spikeweed is one of the twelve plants that appear in the seed selection screen after the player gets the Grave Buster on the online version, the others are: Ice-shroom, Lily Pad, Potato Mine, Threepeater, Tangle Kelp, Jalapeno, Doom-shroom, Torchwood, Tall-nut, Cactus, and Blover.
 * The Spikeweed's flavor text about hockey seems to be in line with its role of destroying Zombonis (a vehicle with a close link to hockey itself) and its main role in the Vasebreaker level Hokey Pokey.
 * If the player looks closely, the Spikeweed's eye pupils are red.
 * The Spikeweed and the Spikerock are the only multi-use plants that cannot be eaten.
 * The Spikeweed, Spikerock, Fume-shroom, and Gloom-shroom are the only plants that attack every zombie within their attack range with the same damage to each.
 * It is unknown why in I, Zombie, Crazy Dave made a cardboard Spikeweed when it cannot be eaten by zombies, although this may be because it can be destroyed or stolen.
 * The color of Spikeweed's plant part looks like mud.
 * The Spikeweed, Spikerock, Lily Pad, Cattail, Tangle Kelp, and Sea-shroom are the only plants that cannot be planted on a Flower Pot.
 * The Spikeweed, Spikerock, Flower Pot, Tangle Kelp, Sea-shroom, and Potato Mine are the only plants that cannot be planted on a Lily Pad.
 * In Vasebreaker, Spikeweed only appears in Hokey Pokey.

Plants vs. Zombies 2: It's About Time

 * If the player unlocked the Spikeweed's costume and uses its Plant Food ability, its costume will disappear for the duration of the Plant Food effect.
 * Unlike the first game, Spikeweed's color is changed to green instead of brown.
 * If the player uses Plant Food on a Spikeweed, all the Barrel Roller Zombies or Pianist Zombies on the lane will not be instantly destroyed, but instead, the plant damages them. This trait is shared with the Spikerock.
 * It is one of the few plants in that has a job outside the game.
 * The Spikeweed's costume from Piñata Party is resembles Groucho Marx.
 * Spikeweed's sound when damaging zombies has changed to a sound like air being leaked out of a bag.
 * If a Spikeweed is planted under a barrel without a Barrel Roller Zombie pushing it, it does not destroy the barrel, and will simply keep attacking the barrel until it's destroyed.
 * The Spikeweed cannot pop Shield Zombie's treads.
 * Spikeweed's Plant Food ability also affects the Zombot Plank Walker, and causes him to pause untill it is over, which will cause him to jump back to where he was.
 * Spikeweed's costume in the Chinese version affects the Plant Food effect, the duration of the Spikeweed pulling the zombies is longer and when a zombie hits the Spikeweed it will spin and become dizzy and walk backwards, like a Hypno-shroom, it hypnotizes the zombies.
