Cactus costs 125 sun and is obtained before Level 4-3, which Balloon Zombies appear. Cactus attacks by shooting spikes at zombies, spikes fired by Cactus deal the same amount of damage as a Peashooter's pea.
Her ability to stretch herself to pop Balloon Zombies is a reference to how Cacti in real life can grow to be some of the tallest plants on earth.
Cactus's main role in the player's arsenal is to shoot down Balloon Zombies before they can get past through the defense, turning them into normal zombies that can be attacked by any other plants. While she will be sufficient in normal levels, the sheer amount of Balloon Zombies that can spawn in Survival Mode, plus its lackluster performance against other threats makes Cactus not a worthwhile choice later on.
Cactus also has to compete with Cattail, which can target zombies from any lane and deal twice as much as damage as the Cactus, but suffers from an aiming issue, as well as Blover, which can clear Balloon Zombies from all lanes and ward off the fog in Fog levels.
A column of Cacti should be planted to safeguard the player against potential Balloon Zombies. Cactus is also a possible candidate for getting the Don't Pea in the Pool achievement, but should not be used given her poor damage capability and the lack of Balloon Zombies in Pool levels - most lobber plants are much more suited for this task.
Plants vs. Zombies Wiki has a gallery for Cactus.
- In Cactus's online Almanac picture, it just shows her neck rising up.
- If stretching, she will be equally the same height to a Tall-nut.
- However, she cannot block vaulting zombies even if she was stretching at the right time.
- She cannot work on the slope in Roof levels unless on the fifth column, despite being able to grow taller.
- She is one of the twelve plants that appear in the seed selection screen after the player gets the Grave Buster on the Web version, the others being Ice-shroom, Lily Pad, Potato Mine, Threepeater, Tangle Kelp, Jalapeno, Spikeweed, Torchwood, Tall-nut, Doom-shroom, and Blover.
- On the loading screen, her pollen balls are red, but during gameplay, they are yellow. In I, Zombie, her pollen balls are orange.
- In Portal Combat, Cacti in the lane of Balloon Zombies will attempt to fire at it even if the spike will go through a portal and end up in another lane. However, Cacti in other lanes that have a portal leading to the correct lane will also shoot at the Balloon Zombie.
- She, Tall-nut, and Garlic are the only plants that appear in I, Zombie, but do not appear in I, Zombie Endless.
- The plural form of Cactus is represented in-game as "Cactuses" rather than "Cacti."
- She is nicknamed "刺头" (lit. "spike head") in Plants vs. Zombies: Journey to the West.
