Blue Field Madder is a
annual plant of the UK, typically found growing in cropland, roadsides and waste ground, to a mature height of up to 40cm.
Blue Field Madder is a trailing plant, with whorls of oval-pointed leaves, and looks similar to the bedstraws, which belongs to the same plant family. Despite the name 'Blue', the flowers are actually more of a pale pink to lilac colour. This is reflected in the colour 'Madder Blue', which is not a true blue but more of a lilac-grey, close to the colour of the flower. To add to the confusion, the roots of Blue Madder, like those of Common Madder, can be used to make natural orangey-red dyes.
Botanic classification and naming: Blue Field Madder is a member of the Madder (Rubiaceae) family. The genus name
'Sherardia' identifies the plant as a Field Madder and its species name 'arvensis' means 'field plant'.
