Flower clocks?

hi can anyone provide me with a good website on floral clocks? i read in some newspapers that some flowers are so good at telling different times that a combination of 12 different flowers can tell the time of a day as each different flower blooms at different times of the day.
Flower clocks?
The period a flower is open is its anthesis. Many flowers close at dusk as the light fades or temperatures cool off. The Swedish botanist Carolus Linnaeus called these Meteorici because they respond meteorological conditions. But to create the timing of a clock he used the ones he called aequinoctales. These are flowers with flowers with fixed opening times that are independent of the weather.


The scarlet pimpernel opens its flower at 8:00 AM and closes it at 2:00 PM. The dandelion opens at 9:00 AM and closes at 5:00 PM. The morning glory opens at 10:00 and closes at dusk. The water lily opens at noon and closes at 2:00 PM. Goatsbeard opens at noon and closes at 6:00 pm. California poppy opens at 1:00 PM and closes at dusk. Chicory opens at 2:00 PM and closes at 5:00 PM.


Four-o'clock opens at 4:00 PM and evening primrose opens at 6:00 PM.
