Flower is an attack effect in the Super Smash Bros. series, which debuted in Super Smash Bros. Melee and has appeared in every subsequent game. Fighters hit by flowering attacks are inflicted with the flower status condition (known as RipStickFlower internally from Super Smash Bros. Brawl onward) for a certain amount of time, based on the attack's damage.
Fighters with the flower condition have a flower visibly emerging from the top of their head. In Melee, Brawl, and SSB4, the flower is a white lily. In Ultimate, the flower is a pink daisy with a visible stamen.
A fighter with the flower condition takes damage over time (1% every 21 frames), until the are freed from the condition. The flower becomes bigger if a fighter that already has the condition is hit with a flowering attack again. Any fighter hit by a flowering attack can be inflicted with the flower status condition, with the exception of Alloys in Brawl.
Starting in Brawl, Flower is one of the rules that can be set in Special Smash, which causes all fighters to permanently have the flower status condition. Additionally, in Super Smash Bros. for Nintendo 3DS's Smash Run and for Wii U's Smash Tour, one of the possible battle types is "Flower Smash", which causes all fighters to permanently have the flower condition, like the Special Smash rule.
The amount of time the flower condition remains is dependent on how much damage the flowering attack did. The formula for flower frames is
