Marchito means "withered" or "faded." It's a poignant and evocative word that paints a vivid picture of decay and the transient nature of beauty.
In the song, Willie Colón uses it to describe a beautiful carnation that, after blooming and showing its beauty, eventually withers and perishes. This metaphor powerfully reinforces the central theme that "todo tiene su final" (everything has its end), making it a memorable and impactful word choice.
"Todo Tiene Su Final" pairs Willie Colón's arrangement with Héctor Lavoe's voice on a plain idea stated over and over: nothing lasts. The opening verses reach for a flower to make the point — "Como el lindo clavel" ("Like the lovely carnation"), "Sólo quiso florecer" ("It only wanted to bloom") — before it withers, same as everything else.
By the time the song settles into its long coro, the mood shifts from mourning to defiance. A verse about losing his mother — "Cuando perdí a mi mama" ("When I lost my mom") — turns into a refusal to look back, capped by "Echa pa delante cobarde" ("Step forward, coward"): if endings are guaranteed, the only choice left is to keep moving through them.
