Power Lily

Power Lily is a plant in Plants vs. Zombies 2: It's About Time. It is a premium plant, meaning it can only be bought using real money. It produces Plant Food for the player out of thin air. It is an instant use plant, meaning, it will vanish once it drops the Plant Food. In the Chinese version of the game, it is unlocked after collecting all stars from the Pirate Seas.

From seedling to sapling, to full grown foliage, Power Lily experience as a life coach has shown her the best way to empower and support plants everywhere.

General
Only use Power Lilies in higher stages if there are few or no zombies that provide Plant Food.

Power Lilies are best used in the Endless Zones, especially after level 30, as the zombies may only drop one or two Plant Food during a level. Plant Food is very helpful for getting tons of sun by using it on Twin Sunflowers, freezing all the zombies with an Iceberg Lettuce, buttering all the zombies with a Kernel-pult, or summoning a deadly melon hail with a Winter Melon. Other than that, the player can also use it by selecting the Power Lily and its duplicate to replenish Plant Food because of Plant Food scarcity on higher levels and as well as on higher zombie concentrations. Without them, the player is forced to use Power Ups in some situations where in killing any zombies getting close to the Player's House is almost impossible.

Endless Zone
In Arthur's Challenge, especially on three digit levels where Wizard Zombies and Gargantuars come in great concentrations, Power Lily makes a great use here but you must have a Tile Turnip. At least four of those can be planted on any desired column but best to be safe, from behind. Then, you can combine the Power of Sun-shroom, Iceberg Lettuce, Laser Bean, Magnet-shroom, Winter Melon, Twin Sunflower, or any of your choice. Not only you just conserve one Plant Food but you were also able to cut off the horde and drastically increase your sun production. You may require boosting plants already.
