Say goodbye to the Botwins. Showtime has confirmed that Weeds upcoming eighth season will be its last.

The dramedy, which premiered in 2005, not only boosted the careers of stars Mary-Louise Parker, Hunter Parrish and Alexander Gould, but was crucial to Showtime's growth as a premium cable network.

"There were two shows, Weeds and Dexter, that really got Showtime taken seriously for cutting-edge original programming," Showtime entertainment president David Nevins told Entertainment Weekly, who first reported the news. "How they get brought home is really important. In this case, both for the sake of the two women behind the show [series creator Jenji Kohan and Parker] and an audience that's really invested in the show. TV fans love nothing better to complain about how shows end and we really want to end this one the right way."
