Petals are items used for flower planting in Pikmin Bloom. To get petals, the player must feed nectar to Pikmin in the garden, which will make a flower bloom on their head. Petals from that flower can then be picked and added to the player's inventory. There are multiple types of petals, each planting different types of flowers on the in-game map.
Petals can mainly be obtained by feeding Pikmin nectar. Each of the several nectar types corresponds to a petal type. Feeding nectar to a Pikmin will make a flower bloom on its head, and tapping that flower will add petals to the player's petal storage. The exception to this is the basic white type of nectar, which will bloom Pikmin from leaf to bud and then bud to flower. If a Pikmin goes from leaf to flower or flower to flower, tapping the glowing flower will give 1 petal of that type. If a Pikmin goes from bud to flower, tapping the glowing flower will give 2 petals of that type. Types of flowers that are not the basic types also have a chance of giving petals of the basic petal type of the same color. Each Pikmin can only be fed nectar 6 times before it will be overfed and lose its flower after it has been tapped.
Some types of petals can also be bought from the shop.
There is a limit to the number of petals of each type the player can hold, but it can be increased through in-app purchases in the shop. The starting amount is 300, though it used to be 200 before July 11th, 2022.
Petals are used in flower planting as a consumable resource. One type of petals can be selected at a time, and when flower planting is turned on, that type of petals will gradually be depleted. They will not be depleted if the app cannot see the player's location, if it cannot connect to the game's servers, or if it is currently in a crashed state. The rate depends on how many Pikmin are in the player's squad, but as the range of flowers planted also depends on this, it's advantageous to have as many Pikmin in the squad as possible.
It is possible to select a different petal type during a flower planting session without interrupting the session, but doing so will instantly consume 1 petal of the newly-selected type.
This table displays the icons of all the petal types, organized by color and flower species. Types with an N/A do not exist in the game.
