"Flower clocks" provided a unique and decorative means of telling time in the formal gardens of nineteenth-century Europe. A series of flowers beds was laid out to form a clock face, with each bed representing a daytime hour. The beds were planted with flowers known to open or close at the prescribed hours. On a sunny day, the time on a flower clock could be determined to within a half-hour.

　　19世纪欧洲正规的花园里的"花卉钟"以其独特的装饰性的方式告诉人们时间。人们将各种不同的花卉种成一个一个钟面，每个花床代表白天一个钟点，花床上种植着预计在某一时间开放或闭合的花。晴天时，可根据花卉钟判断时间，误差不超过半个小时。
