The scarlet pimpernel (Anagallis arvensis; also known as the red pimpernel, red chickweed, poorman's barometer, shepherd's weather glass, or shepherd's clock) is a low-growing, annual plant in the family Myrsinaceae, growing in Europe, Asia and North America.

The barometer (weather glass) common names have their origin in the fact that the flowers close when atmospheric pressure decreases and bad weather is approaching.

This common European plant is generally considered a weed and is an indicator of light soils.
