Identified Plants & Fungi
Identified Plants and Fungi are plants and fungi that have been identified in-game and have a definitive name that they are refered to as.
Candypop Buds
Candypop Buds appear in all of the Pikmin games and serve the purpose of switching Pikmin colors.
Clover
Clovers appear in all of the Pikmin games but serve a purpose only in Pikmin 3, in which they act as a hiding place for Pikmin. In Pikmin 3 Clovers are quite rare, only appearing in the Garden of Hope in story mode and in Mission mode they appear in the Tropical Forest and Shaded Garden .
Horsetail
Horsetails appear in Pikmin 2. They serve no purpose other than asthetics.
Shoot
Shoots appear in all of the Pikmin games. In Pikmin 3, they primarily serve as a place for Aracnodes to make webs, otherwise they are asthetics.
Pellet Posy
Pellet Posies appear in all of the Pikmin games and they always serve as a way to produce more Pikmin. They also never appear on the final area of each game.
Dandelion/Seeding Dandelion
Dandelions and Seeding Dandelions are found in Pikmin 2 and Pikmin 3. They serve no purpose aside from asthetics. Seeding Dandelions' seeds can be dispersed by running into the flower. Oddly enough, despite being common in real life, Dandelions are rare in Pikmin.
Burgeoning Spiderwort
Burgeoning Spiderworts are found in Pikmin 2 and Pikmin 3. They serve the purpose of obtaining sprays. In Pikmin 2, they come in three types, Ultra Spicy, Ultra Bitter, and a rarer Mix of the previously mentioned. In Pikmin 3, the only type is Ultra Spicy.
Figwort
Figworts are found in all of the Pikmin games. They don't serve any purpose other than asthetics.
Flukeweed
Flukeweed appears only in Pikmin 3. They can be uprooted by Winged Pikmin to expose a variety of things, such as fruit, male or female sheargrubs, 1 or 5 pellets, eggs, bombrocks, sprays, or, in one case, a Blue Onion.
Common Glowcap
Common Glowcaps appear in every Pikmin game and are always used for lighting. In Pikmin 3 some Glowcaps have to be activated. It is most-likely that Blue Common Glowcaps are based on Pixie's Parasol mushrooms.
Foxtail
Foxtails are only found in Pikmin 2 and are actually quite rare, only appearing in two areas of the game, the Valley of Repose and the Wistful Wild.
Bloominous Stemple/Bluminous Stemple
Bloominous Stemples/Bluminous Stemples are only found in Pikmin 3 in caves and are able to function as bridges. They are one of four plants seen in the Pikmin games that react to light, the others being Onions, Pellet Posies, and Glowcaps.
Unidentified Plants & Fungi
Unidentified Plants & Fungi are plants and fungi that are never given a name in-game and therefore are usually refered to by a nickname, brief description, or are called what the actual item is in real life.
Red Mushroom
The Red Mushroom appears in Pikmin and Pikmin 3, it is never identified and it doesn't have any purpose other than asthetics. It is possible that the Red Mushroom could be based on the Mycena haematopus.
Long Grass/Nectar Weed
Nectar Weed appears in both Pikmin and Pikmin 2. it is never identified, but is given the nickname, Nectar Weed, due to the fact that when plucked by Pikmin, it produces Nectar.
Spiked Grass
Spiked Grass appears only noticibly in Pikmin. It serves no purpose other than asthetics.

(Snow Lady) Shasta Daisy
The (Snow Lady) Shasta Daisies only appear in Pikmin 3. They serve no purpose other than asthetics and are usually found near some Yellow Wood Sorrel.

Forget-Me-Nots appear only Pikmin 3. they are only located in two places, the Mission Mode stage Beastly Cavern, and the Bingo Battle stage, Shaded Terrace.
Sprout
In addition to Clovers, Pikmin 3 introduced sprouts, they have the same purpose as Clovers do.
