A charming composition of flowers and symbols creating a stylized clock face painted by the famous Silesian artist and illustrator Jarek Nocoń, shows the most important species of plants used in creating a natural flower clock. In the corners we placed allegorical female figures symbolizing the seasons. A flower clock is an original idea of ​​using the natural properties of plants to measure time. This unconventional timepiece is based on the observation of the life cycle of flowers, which open and close their petals at specific times of the day. This idea uses the circadian rhythms of plants, which are naturally synchronized with the rhythms of the environment, mainly with changes in sunlight. The idea of ​​creating a flower clock comes from the observation of the natural behavior of plants by the famous botanist, Carl Linnaeus. In the 18th century, Linnaeus noticed that different species of plants open their flowers at fixed and predictable times of the day, which inspired him to use these phenomena in practice to measure time.
