Cui Jian's 1991 song 《
花房姑娘》 ("Greenhouse Girl") - about a girl who lives among flowers and lures the narrator away - is one of the most recognizable Chinese rock songs of all time, and the main reason most younger Chinese speakers know the word. Compare
温室 (wēnshì), the modern technical term for a heated commercial greenhouse;
花房 leans poetic/old-fashioned.
