Stallia is the fourth plant obtained in Lost City in Plants vs. Zombies 2. It was first revealed in the Lost City Part 2 trailer and its gameplay function was revealed in the developer diary of the aforementioned update.
When a zombie comes close to Stallia, the Stallia will release a purple perfume that slows down all zombies in a 3x3 area for 12 seconds, and lasts longer when levelled up. The perfume does not stack with other slowing effects, such as the chilling effect from any ice-based plant, or the sap laid down by Sap-fling. Stallia also gains the ability to knockback zombies after reaching level 5 in the international version of Plants vs. Zombies 2.
Stallia is based on the flowers of the genus Dahlia. Its name is a portmanteau of "stall," which reflects its stalling ability, and the aforementioned Dahlia.

Stallia fills in the middle ground between slowing plants and instant use plants. Its main advantage is that it costs no sun to use and has a wide area of effect, making it the earliest slowing choice available in the early game. However, Stallia's slow recharge and its lack of synergy with other slowing plants will greatly reduce its effectiveness later on as it will fail to control all lanes, although the use of Imitater may somewhat remedy its recharge problem.
When compared with Stunion, similarities between the plants are quite noticeable. They both prove to be more or less equally useful but situational. They are also great in conjunctions with the Ghost Pepper, Spikeweed, Spikerock, Cactus, or Lava Guava, as the zombies are forced to spend more time being haunted, spiked, or burned by the lava. Stunion costs the minimum amount of spendable sun, but it does not matter much as it can even be dug up. It has the ability to stun a group of zombies for a large amount of time, longer than Stallia's slowing time. However, it is locked to its lane. The weight on Stallia's scale is the fact that it can slow machine zombies in Far Future, while Stunion cannot. When it comes down to choose, it is ultimately a preference for the player as they both have many good things for themselves.
Lastly, Hurrikale's ability to chill zombies has never been a very important aspect of it, as the focal point is on its pushing ability which efficiently delays zombie attacks. When compared to Hurrikale, Stallia is undesirable in some situations, due to the fact that even its slowing is not enough to delay the zombies if the player's defenses are still weak. This is especially true with flying zombies and zombies with a high amount of health points. In this sense, it is up to the player to determine what plant is adequate for the level if the situation that requires the player to either choose one of them only.
Once Stallia reaches Level 5, it gains the additional ability to knock zombies back. Besides making it more useful by pushing zombies back in addition to slowing them down, it also can be used as a very cheap and effective zombie removal if used alongside Blover. If timed right, a level 5 or more Stallia combined with Blover will take out a 3x3 area of zombies susceptible to knock back, including Gargantuars.
An interesting thing to note about Stallia is that its hitbox lingers for a bit after use; if planted on the same tile as a zombie, it will attempt to eat it/use abilities on it, despite it not being there anymore. This can be useful in delaying the more dangerous zombies, like Newspaper Zombies, All-Star Zombies, and even Gargantuars.
Plants vs. Zombies Wiki has a gallery for Stallia.
- It is mostly believed that Stallia is female. However, its gender is not mentioned in the Almanac, and there is no canon evidence on its gender.
- Its Plant Food ability makes the same flash as Iceberg Lettuce's. The only visual difference is that the flash is purple.
- "Folks need to slow down and smell some spores" is a pun on the famous expression "Folks need to stop and smell the roses."
- When using an ice-based plant in combination with it, the zombies will turn dark blue. The slowing effect does not stack, however.
- This also happened with Sap-fling and ice-based plants but zombies change to the color green, although it is now removed.
- Before the 3.9 update, it could be used in Last Stand levels.
- Sometimes, it will only activate when a zombie makes direct contact. Two examples are when a Gargantuar attempts to smash it or when Excavator Zombie tries to shovel it.
- When a zombie is burned or electrocuted while still under the influence of its stalling effect, the perfume cloud will be still visible until that zombie disappears.
- Its night cap costume is a reference to its "sleepy-looking" eyes. In a similar sense, the lion costume is a visual pun on the design of its petals.
- Both costumes coincidentally line up with the song The Lion Sleeps Tonight.
- It can sometimes be killed by Pianist Zombie.
- This also happens with Shrinking Violet.
- It and Perfume-shroom are the only plants to use perfume.
- While its perfume merely slows zombies down, Perfume-shroom's perfume instead does nothing to zombies, but instead charms dinosaurs.
- Stallia can cause the game to lag on some older Android devices if multiple amounts of zombies get slowed.
