Lysimachia monelli

L. arvensis, and some authors had even included L. foemina as a subspecies of L. arvensis.^{[citation needed]} The three species were among several transferred from Anagallis to Lysimachia in a 2009 paper.^[3]

perennial with trailing stems. Wild specimens have blue or orange coloured flowers and are not sympatric with the blue-flowered plants growing natively in southern Spain and the orange in Morocco and southern Italy. A red variant was also developed by breeding at the University of New Hampshire. The orange-coloured flowers have a higher concentration of pelargonidin pigment, while blue flowers have a higher concentration of malvidin. The red-coloured flowers are due to the relative concentrations of delphinidin and malvidin pigments. In addition to the blue, orange and red forms, a white form of the flower also exists.^[4][5]

temperate regions this plant is often grown as an annual. As Anagallis monellii it has gained the Royal Horticultural Society's Award of Garden Merit.^[6]
