Self-proclaimed nerd Seymour Krelborn, an adolescent boy who works in a flower shop, keeps a pet Venus Flytrap named Junior. Junior sprouted from a 200-million year-old seed and has the ability to talk and hypnotize people. Only Seymour is aware of Junior’s abilities. The flower shop is owned by stodgy Mr. Mushnik, whose daughter Audrey is the object of Seymour’s affections. Audrey, however, does not seem to reciprocate his feelings. Buck-toothed Paine Driller, a neighborhood bully, continuously targets Seymour.
Episodes focused on the pubescent exploits of the leads and frequently featured a moral. They also featured a couple of musical numbers per episode. Consistent with the “urban” persona of the plant in the musical, Audrey Junior raps in the series during his numbers, and speaks in a hip-hop dialect. Also featured are a trio of singing flowers reminiscent of Crystal, Ronette, and Chiffon (the three chorus girls in the musical).
