About Rough corncleavers
Galium tricornutum, known as ballastmaure or three-horned bedstraw, is an annual plant belonging to the Rubiaceae family, characterized by its angular, rough stems and small white flowers arranged in cymes. Its leaves are borne in whorls and are lanceolate with serrated margins. This plant is often found in cultivated fields and along roadsides, where it can form low, unassuming ground cover.
Native range
Mediterranean region and Southwest Asia.
Care tips
It thrives in full sun to partial shade and well-drained soils, although it is adaptable to a variety of soil conditions. Watering should be moderate, allowing the substrate to dry out slightly between waterings, as it tolerates some drought. While not a common ornamental plant, if you wish to control its spread in a garden, it is crucial to remove plants before they produce seeds. A common mistake is confusing it with other Galium species, which can lead to inappropriate treatments if attempting to eradicate it from a cultivated area.
