Blue pimpernel
Blue Pimpernel (Anagallis arvensis var. caerulea) is a variety of the flowering plant species Anagallis arvensis, commonly known as the scarlet pimpernel, in the family Primulaceae. The blue pimpernel is distinguished by its blue flowers, as opposed to the red or orange flowers of the typical scarlet pimpernel.
Description[edit]
The blue pimpernel is a low-growing annual plant that reaches a height of 5 to 30 cm. It has square stems and lance-shaped leaves that are arranged in opposite pairs. The blue flowers are solitary and borne on long stalks. They have five petals and are approximately 1 cm in diameter. The flowers open in sunny weather and close in the evening or during cloudy conditions, a characteristic that has earned the plant the nickname "poor man's weatherglass".
Distribution and Habitat[edit]
The blue pimpernel is native to Europe, Asia, and North Africa. It has been introduced to other parts of the world, including North America and Australia, where it is often considered a weed. The plant prefers open, sunny locations and is commonly found in fields, pastures, and along roadsides.
Cultivation and Uses[edit]
While often considered a weed, the blue pimpernel is also cultivated for its attractive blue flowers. It is suitable for rock gardens and as a ground cover. The plant requires full sun and well-drained soil. It is drought-tolerant and can thrive in poor soil conditions.
In traditional medicine, the blue pimpernel has been used to treat various ailments, although its efficacy is not scientifically proven. The plant is considered toxic if consumed in large quantities.
