Scarlet Pimpernel

Anagallis arvensis

Scarlet pimpernel is seldom a weed problem. It is also called red chickweed because the leaf shape is so similar and it is a prostrate plant. Another name, poor man's weatherglass, alludes to the fact that the flower closes at the approach of bad weather. An annual reproducing by seeds.
