Stallia

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 10 seconds. 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.

Origins
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.

Almanac entry
Sun cost: 0

AREA: 3x3

RANGE: Touch

RECHARGE: Sluggish

Stallias slow down zombies with a puff of perfume.

"Life moves too quickly in our modern world," says Stallia. "Folks need to slow down and smell some spores."

Plant Food effect
When fed with Plant Food, Stallia releases perfume that covers the entire screen in a purple shade for a split second, slowing all present zombies for ten seconds.

Costumed
Stallia will slow and poison all zombies on the lawn.

Strategies
Stallia fills in the middle ground between other 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 both great in conjunction 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 choosing, however, it is ultimately a preference of the player as they both have many good things to them.

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 is such that only one of them can be chosen.

The player should be cautious when using Stallia in the Dark Ages because Stallia cannot stall Jester Zombies while they are spinning.

Trivia

 * 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 Stallia, 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, Stallia 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 Stallia's 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 Stallia's petals.
 * Both costumes coincidentally line up with the song The Lion Sleeps Tonight.
 * It can sometimes be killed by Pianist Zombie.
 * It and Perfume-shroom are the only plants to use perfume.
 * While Stallia's perfume merely slows zombies down, Perfume-shroom's perfume instead does nothing to zombies, but instead charms dinosaurs.
