TARDIS gardens
From Tardis Wiki, the free Doctor Who reference
The TARDIS gardens were gardens located within the Doctor's TARDIS.
There was a large garden designed by the Doctor using Block Transfer Computation that needed to be tended — it contained bougainvillaea, Draconian myrtle hedges and Vendican bladder-pods, plus a stream and set of swings. The Eighth Doctor said he once allowed an entire incarnation to pass without maintaining it. Charley called it the Doctor's 'pride and joy'. (AUDIO: Scaredy Cat)
During the time when Jason and Dr. Who controlled the TARDIS, Jason almost drowned Wolsey in the garden's pond. (PROSE: Head Games)
