Gardening with Maurice was a radio talk show that aired from around 1992-2001. It was on the San Andreas radio station WCTR Talk Radio in Grand Theft Auto: San Andreas. Maurice, the host of the show is an exhibitionist who likes to take pictures of himself in the nude, and also when he's "blossoming". He photographs himself along with his flowers when they too are blossoming.
The show is most famous for having a caller from Bone County complaining as to why she's unable to grow any flowers (due to Bone County being a desert region). The callers are largely female. In Grand Theft Auto III's Chatterbox FM, a caller asks Lazlow about flowers; Lazlow says "this isn't Gardening with Maurice, that's on later," to which the caller replies "no, he got taken off the air," assuming the show came on in Liberty City. This means that the show either aired nationally, or moved to Donald Love's Chatterbox FM (or LCFR) sometime after 1992.
