Galium trifidum |
Galium trifidum is a species of flowering plant in the coffee family, known by the common name three-petal bedstraw.[1] It grows widespread in the arctic, temperate and subtropical regions of the Northern Hemisphere: northern and central Asia (Siberia, the Russian Far East, China , Korea, Japan , Kazakhstan), northern and eastern Europe (Scandinavia, France , Austria, Poland , Russia , Ukraine , Baltic states) and much of North America (from Greenland and the Aleutians as far south as Oaxaca and Hispaniola).[2][3][4]
Galium trifidum is a usually perennial herb forming tangles of thin stems up to half a meter long, ringed with whorls of several linear to oval leaves. The inflorescence is a cluster of small white or pinkish flowers, each with usually three petal-like lobes in its corolla.[5][6][7]
