• Pimpernel (Anagallis Arvensis Caerulea) - This unusual little plant is originally from Europe. Known as Blue Pimpernel, it has a spreading habit which makes it well-suited for edging a border, as a general ground cover plant, and in pots and hanging baskets. The Blue Pimpernel flower is open only when the sun shines.
• The habit of closing in dull weather and when rain is approaching has given the plant the name Poor Man's Weather-Glass. This caerulea variety of Anagallis is not as famous as Scarlet Pimpernel, but you cannot go wrong with adding this blue version to your flower garden. The Blue Pimpernel plant establishes easily and quickly grows and spreads to produce nice ground cover plants.
