About this weed

There are two varieties of Pimpernel: one with bright blue flowers and the other with bright orange to red flowers. Both varieties have similar features although the blue variety is usually more robust. Both varieties originated from Europe and were probably introduced with horticulture. The Genus Anagallis has been renamed Lysimachia but some references still refer to the former Genus.


Pimpernel is a low spreading annual with more or less square stems producing orange or blue flowers about 1 cm across in spring.
