Bonsai
From Tardis Wiki, the free Doctor Who reference
Bonsai was an art form that involved the manipulation of plants. Harrison Chase saw it as torture and considered the World Ecology Bureau hypocritical for not banning it. (TV: The Seeds of Doom)
Satellite Homes and Gardens had an article on zero-g bonsai in the 101st century. (PROSE: Synthespians™)
