Bamboo
From Tardis Wiki, the free Doctor Who reference
Bamboo was a plant native to Earth.
Iris Wildthyme's companion Panda enjoyed nibbling on bamboo while in meetings, (AUDIO: Wildthyme at Large) and as an ingredient in Bamboo Upside-down Cake. (PROSE: Deleted Scene from 'Iris Wildthyme and the Key Lime Pie 2 Time' - 'Part 3: The Stones of Blood')
