What is flower clocks?

A flower clock is a clock that uses the timing of flowers to tell time. The idea dates back to ancient civilizations, but it became popular in the 18th and 19th centuries. Flowers open and close at predictable times of day, and different flowers open and close at different times. The flower clock typically consists of a garden or series of gardens containing different types of flowers that open and close at different times. The clock is read by observing which flowers are open or closed at a given time of day. The flower clock was invented by Carl von Linné, a Swedish botanist, in 1751, and it was popularized by the French naturalist Jean-Jacques Rousseau in the 18th century. Today, flower clocks are still used for decoration and as a way to connect with nature, but they are not generally used as a method of telling time.
