Flower Behavior.

Flower power

There are a number of flowers that you should look for if you want to know what the weather will be like. One of these is the Scarlet Pimpernel, which has been called the "poor man’s weather glass". This is because its flowers open in sunny weather, but close tightly when rain is expected.

The petals of the Morning Glory act in a similar way – with wide open blooms indicating fine weather and shut petals predicting rain and bad weather. This opening and closing also occurs with the South African magic carpet flower.

Flower folded itself and bundled to protect itself from the cold weather.
