|Oh sure, everyone knows Stunion as the battle-hardened warrior with the potent breath. But he's so much more than that. He's an accomplished pianist. He speaks five languages fluently. Heck, he's the leader of a Cub Shallots group in his spare time. Dude's got layers. Go on, peel 'em back. You'll see.|
Stunion is the fourth plant obtained in Frostbite Caves in Plants vs. Zombies 2. It is a single-use plant and when zombies get close to it, it releases a cloud of gas in a 1x2 area in front of itself, similar to the one emitted from a zombie defeated by Chili Bean, stunning the affected zombies for 12 seconds. The gas cloud does not affect mechanical enemies, except for Zombie Bulls, Gargantuar Primes, Treasure Yetis, and Bug Bot Imps.
Stunion is based on the plant Allium cepa, also known as the common onion in Modern English. It is usually used as an ingredient in cooking, thanks to its distinctively pungent taste and aroma. Its name is a portmanteau of "stun," an act of driving someone into an unconscious or semi-conscious state, and "onion," the plant it is based on.

*After reaching Level 5, Stunion will gain the ability to poison the zombies it stunned. This column will show the damage-per-second the effect deals on the affected zombies.
Compared to Iceberg Lettuce, Stunion can stun all zombies in its area of effect instead of just one target. The stunning effect is not nullified by fire-based plants and also works in Frostbite Caves, where Iceberg Lettuce can only slow instead of stop enemies. However, Stunion does not work on mechs and costs more sun than Iceberg Lettuce. In most cases, though, its slightly bigger price will not matter. On the other hand, its Plant Food effect is significantly worse—while Iceberg Lettuce's plant food ability affects the entire screen, Stunion's plant food ability only affects a limited area.
In Dark Ages, Stunion can be used to prevent Jester Zombie from reflecting projectiles. However, the same is not true for Parasol Zombie and Excavator Zombie in Lost City, as they can neutralize projectiles even when stunned. If using Stunion against MC Zom-B during rap, make sure to plant it on the square that MC Zom-B is on or the one in front, otherwise MC Zom-B can kill it with its microphone which has longer effective range.
Stunion should not be used in tandem with Primal Peashooter, as the latter's knockback will remove the stun effect, rendering Stunion useless. Iceberg Lettuce should be used in this situation instead, since its freezing effect is not interfered by Primal Peashooter.
At Level 5 and above, Stunion gains an armor-piercing poison effect akin to Shadow-shroom on stunned zombies and thus can be used more offensively against weaker zombies and headwear zombies. A single use can defeat Chicken Wranglers and Weasel Hoarders without releasing their animals due to the stun, and also kills headwear zombies in one use.
Plants vs. Zombies Wiki has a gallery for Stunion.
- It can stun flying zombies, unlike Iceberg Lettuce and Chili Bean.
- When it disappears, it makes the same sound as Puff-shroom when dying.
- If it stuns a zombie and that zombie dies before the effect is gone, the zombie's body will just remain there, standing still until the stun effect ends and the body collapses. The gas cannot be seen.
- At maximum level, Stunion can poison zombies like Shadow-shroom in addition to stunning zombies.
- If a stunned zombie is pushed back by Hurrikale and lands up on a slider tile, it will remain there until the gas disappears.
- Its tongue is green, as seen whenever it opens its mouth to stun zombies.
- It and Chili Bean both use the same gas to stun zombies. They are also the only plants able to do so.
- Apple Mortar can also stun zombies, but for a very brief period of time.
- For a brief moment after stunning, it can be shovelled for sun.
