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]
