- For the item, see flower pot.
While it is intended for use on the roof, they can still be planted on a regular grass tile, but they cannot be placed in the pool (even if on a Lily Pad).
It is based on the flower pot in real life, a place to put flowers in, similar to how plants can be planted inside flower pots.
Suburban Almanac entry
The player should first place the Flower Pot on a roof tile, and then place a plant in it. Flower Pots cannot attack, and do not do anything outside of the Roof levels other than having a slight resistance to chewing. Flower Pots are required to plant any explosives like Cherry Bombs or Doom-shrooms on Roof levels. If a Doom-shroom detonates on top of it, it is destroyed, in addition of creating a crater, which plants can’t be place on for an amount of time
One of the most durable anti-zombie barriers in the game combining a Flower Pot or Lily Pad, a Pumpkin, and a Tall-nut. Together, these plants which will hold a single regular-speed zombie for upwards of four minutes which is even longer when combined with movement-restricting plants such as Snow Peas and Winter Melons. However, this provides less protection for its sun than a standalone Tall-nut.
This plant is essential to your survival in all worlds past Roof, as all of them (except for underwater ones) require Flower Pot in order to use plants.
You might be able to sneak without it in War of The Spider Woman and Three Fights With Skeleton Demon as only one or two lanes require Flower Pot and there are three preplanted ones on each lane, but they are heavily required in boss battles in all areas.
Given how the player cannot plant on the Roof otherwise, the player should always take it whenever they play a Roof level. However, there are a few select situations where it can be used elsewhere, despite it not being recommended by the game.
If you want to slow down zombies on the roof, a combination would be a Puff-shroom (by itself, asleep) or Wall-nut or Tall-nut on a Flower Pot, possibly coated with a Pumpkin (which gives a three-layer defense). Flower Pot can also be used to slow down Gargantuars and cause Pole Vaulting Zombies to lose their pole.
They are usable off the roof, allowing it to be used defensively similar to a Pumpkin (it will not help the plant in it, but it will buy some time for the plants on the left after the plant in it gets eaten). Note that you must plant the pot before you put the plant if you want extra defense.
It is not recommended for ground levels, even though they can be planted on the ground, as planting one will just waste 25 sun and waste 1 slot (unless you are using it defensively).
- On Level 5-1, the player will be provided with five columns of Flower Pots. The player will be provided with four columns of Flower Pots in Level 5-2, and the rest of the Roof levels will have three columns, with the exception of Column Like You See 'Em which has eight columns of Flower Pots.
- It is one of the six plants that can preexist at the start of a level; the others are Sunflower (Versus Mode), Cob Cannon (Buttered Popcorn), Peashooter (Heat Wave, Wall-nut Bowling for the first time in Adventure Mode), Lily Pad (Heat Wave), and Wall-nut (in Can You Dig It?, Heat Wave, and Squirrel).
- It is the only plant in the Suburban Almanac with a Roof background for its entry. This is because Flower Pots are only needed for planting on the roof.
- It cannot be obtained for the Zen Garden by normal means. This may be due to the fact that it does not make sense to have a Flower Pot inside of itself. It is also the only non-upgrade plant besides Imitater, Explode-o-nut and the giant plants that cannot be obtained in the player's Zen Garden.
- Flower Pot and Imitater are the only plants which can be planted on multiple types of tiles without the help of other plants.
- When the player plants on an imitated Flower Pot, it will turn brown, which is its original color. If they remove that plant, it will revert to gray. This only happens when the 3D Acceleration is turned off. when it is turned on Imitater Flower Pots will always have a gray color.
- Even though the Roof is made of tiles or bricks, when the player plants a Flower Pot on the roof, soil will appear out of the Flower Pot's bottom like it has been planted on the lawn.
- When it is planted, it bounces, but it does not bounce when there is a plant on it or when it is being stolen by a Bungee Zombie.
- Spikeweed and Spikerock cannot be planted in Flower Pots, as it is pointless to have a plant that hurts zombies stepping on it if the zombies cannot get on top of it. This would mean if the player could plant Spikeweed or Spikerock in a Flower Pot, then zombies would probably eat the Spikeweed or Spikerock, which contradicts with the said plants' functionality as they aren't supposed to be eaten.
- When a plant gets planted in it, the soil turns from a light brown to a dark brown.
- Flower Pot along with Tangle Kelp, Spikeweed, Spikerock, Potato Mine, and Sea-shroom are the only plants that cannot be planted on Lily Pads.
- It can be hit by Peashooter Zombie and Gatling Pea Zombie, despite that it is clear the peas go over the Flower Pot. The most reasonable explanation is that Flower Pots are not programmed to be faced with those zombies.
- Along with Lily Pad and Pumpkin, it is one of the three plants that can be destroyed by Doom-shroom.
- In Last Stand: Roof, if the player sells the preexisting Flower Pots and does not plant in that space, when the next flag starts, new Flower Pots will fill that space. This trick can be used to gain a little more than the given sun.
- Although it is considered a plant in Plants vs. Zombies, the only part of it that has to do with a plant is the sprout growing on it.
- It is possible to have a plant be put on a rooftop without Flower Pot but this is very rare and can only be obtained via a glitch.
