What is the name of a yellow flower or any flower that closes immediately when wet (rain)?
Many flowers close at dusk as the light fades or temperatures cool off. For those that are light sensitive they will similarly close with heavy cloud cover. The Swedish botanist Carolus Linnaeus actually worked out a clock based upon flowers to tell time.


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 primose opens at 6:00 PM.





This is the origin of the weather saying:


When the pink-eyed pimpernel closes in the day time it is a sign or rain.


Pimpernel, pimpernel, tell me true


Whether the weather will be fine or no;


No heart can think, no tongue can tell,


The virtues of the pimpernel


Folk lore journal from 1889





Closed is the pink-eyed pimpernel:


`Twill surely rain;


I see with sorrow,


Our jaunt must be put off to-morrow.





Anagallis arvensis is the Scarlet Pimpernel. The petals are very sensitive, the flowers closing at once if the sky becomes overcast and threatens rain. Typically opening between eight and nine in the morning and shutting up before three o'clock in the afternoon.





The flowers of Oxalis martiana open in the morning and close in the afternoon also.





Tulips %26amp; crocus close when it gets cooler primarily but they also respond to light this way.


The purpose of closing may be to protect the reproductive organs when the day pollinators are not available. Bees for example need bright, warm weather to fly.
