- For more information about the plant that this line was based on, see Citron.
The Citron line (柚子系; pinyin: yòuzi xì) was a Class S 
Brave
plant line in Plants vs. Zombies: All Stars. It was added in the v1.0.88 update, being released alongside Far Future, the Peach line, and the Energy Bean line.
The line consisted of Small Kumquat (小金桔; pinyin: xiǎo jīn jí), Citron (充能柚子; pinyin: chōng néng yòuzi), and Super Citron (超能柚子; pinyin: chāo néng yòuzi). They all attacked zombies by firing plasma balls at them and specialized in dealing with mechs.
Origins[]
All members of the Citron line were based on various members of the Citrus genus.
The first tier, Small Kumquat, is based on the kumquat (Citrus japonica), a tiny, oblong-shaped citrus fruit native to South Asia and the Asia-Pacific region known for its sour juice and sweet-tasting peel.
The second tier, Citron, is based on the plant from Plants vs. Zombies 2 of the same name and appearance.
The final tier, Super Citron, is based on the regular Citron as well as the grapefruit (Citrus paradisi), a hybrid citrus between a sweet orange and pomelo, known for its extreme sourness and ability to burn fat.
The line's addition in the Far Future update of Plants vs. Zombies: All Stars is a reference to the original Citron being an unlockable plant in Plants vs. Zombies 2's Far Future.
