Big Flowers are plants in Pikmin Bloom that can be found throughout the world at set points of interest. They appear on the map screen with circles around them with a radius of 40 meters. If a player is planting flowers within the Big Flower's radius, it will contribute towards blooming the Big Flower. After 300 flowers are planted in the radius, the flower will bloom and reward players who plant flowers nearby with an expedition to collect a fruit from it. (If a player has not yet unlocked the ability to do expeditions, they will not get a reward from a Big Flower.) Any player that walks within 100 meters of a blooming Big Flower can swipe vertically across it while viewing its information page to gain 1-2 nectar, even if they have already retrieved the fruit. The nectar provided by the Big Flower depends on the type of flowers that were planted in the radius.
A Big Flower has 3 stages:
Each time a Big Flower grows to its next stage, it will flash in light and change in appearance. In addition, when more than 150 flowers are planted in the radius, the bud will flash and falling petals will temporarily surround it.
When a Big Flower blooms, the type of flower it becomes depends on the flowers planted inside its radius. The color of the flower (and therefore the type of fruit it provides) depends on the color of the planted flowers, and the species of the flower (and therefore the species of nectar the fruit provides) depends on the species of the planted flowers.
A Big Flower's eventual bloomed color is determined by the color of the flowers that players plant within, with additional complexity added by white flowers. For red, blue, and yellow flowers, having a majority of that color of flower planted within the radius will cause the Big Flower to grow into that color. For a Big Flower to grow into a white flower, at least 70% of the flowers in the radius need to be either white, or another color that is not the most prevalent non-white color, and when the 300 flower goal is reached, the color of the Big Flower will still be randomly picked.
The likely eventual color and type of a Big Flower is displayed in the screen that appears when an unbloomed Big Flower is tapped. The color displayed does not guarantee that it will be the final color of the Big Flower, because it could still change as more flowers are planted. The colors "red", "blue", and "yellow" will display in this message if that color of flower is the most common non-white color within the radius, and if the 70% rule for white flowers has not been reached. The color "white" is never displayed here, as if the 70% rule has been reached, the color will be displayed as "???" instead. For example, if there are 40 white flowers and 30 red flowers within a Big Flower's radius, the Big Flower will say it will be red, because there are less than 70% white and non-red flowers. If an additional 20 yellow and 20 blue flowers were planted within, they would contribute to white as there are less common than red flowers, and the Big Flower would display "???" as its eventual color.
There are 2 main categories of flower types: basic flowers (from standard petals), and rare flowers (such as pansies, camellias, and roses). If only basic flowers are planted within the radius, the Big Flower will most likely be some color of basic flower, with a small chance of being a rare flower. If mostly rare flowers are planted within the radius, the Big Flower will most likely be the most common type of rare flower, though with some additional complexity and randomness. The chances of different flower species blooming has varied throughout the game's lifespan, and events have frequently added temporary boosts to certain probabilities.
Throughout the game's lifespan, the flower species Big Flowers commonly provide has changed frequently to add variety. Originally these changes happened in a rather inconsistent way, but since March 2022 there has been a consistent monthly flower system. Whenever a Community Day event occurs, all Big Flowers will bloom into the flower the event is themed around for the duration of the day, no matter what flowers are planted in the radius.
When the game was released in October 2021, there were two tiers of rare flowers: pansies and roses. Planting regular flowers in the radius would usually make the Big Flower bloom into a regular flower, but there was a small chance that it would bloom into a pansy. Planting pansies in the radius would usually make the Big Flower bloom into a pansy, but there was a small chance that it would bloom into a rose. This made roses very hard to get.
The second Community Day on December 18th, 2021 introduced poinsettia flowers. After that date, poinsettias replaced pansies as the main rare flower, though planting mostly pansies inside the radius continued to bloom a pansy, and this method of blooming out-of-season flowers has continued ever since. Planting poinsettias or pansies had a low chance of making a rose bloom.
On January 1st, 2022, camellias were introduced, and these joined poinsettias as rare flowers that had a low chance of blooming when regular flowers were planted. After the Community Day on January 22nd, poinsettias were no longer available this way. On February 11th, plum blossom flowers were introduced, and now, planting regular flowers had a chance of blooming pansies, poinsettias, camellias, or plum blossoms. The Valentine's Day event on February 14th made roses very common for the day and lowered the rarity of the type.
From March 2022, the system of flower availability from Big Flowers was simplified, and now each month, planting regular flowers around a Big Flower has a chance of blooming a selection of rare flowers. The second tier of flower rarity was removed, and now roses are treated the same way as other rare flowers. Community Days continue to change the flower availability for that day only. The following table shows the flower types available each month:
These are the sprites used for each type of Big Flower in the screen at the end of a flower planting session.
