Galium album, the white bedstraw or hedge bedstraw, is a herbaceous annual plant of the family Rubiaceae.[3][4]

Description

The stems can grow to at least 150 cm and are more or less erect with ascending branches. The stem is square in section with slight flanges. The plant is relatively hairless with shiny leaves and stem. Flowers are white or yellowish.[5] The fruit are hairless.[6][7]

Habitat and distribution

Galium album is widespread over much of Europe, being native to a large region from Britain to Morocco, east to Turkey and Western Siberia. It is naturalized in Ireland, Scandinavia, Greenland and South Australia.[1] It is found in pastures, grassy banks, etc., especially on dry calcareous soils. In Britain, G. album is local in lowland England, rare in the north and very rare in Scotland.[5]
