Galium porrigens (Climbing bedstraw) is a native California shrub in the Rubiaceae family, recognized by climbing habit with recurved clinging hairs and berry fruits.

Climbing bedstraw is a California native perennial vine found in coastal and inland mountain ranges in chaparral, forest, and woodland habitats. Flowering from May to August, this plant produces small, rotating flowers ranging from yellow to reddish in color. Growing with slender, woody stems 1 to 15 decimeters long that cling and climb by recurved hairs, it develops a distinctive climbing habit. Its leaves grow in whorls of 4, each 2 to 18 millimeters long with acute to rounded tips, creating a delicate, intricate foliage pattern. The plant produces small glabrous berries, completing its complex reproductive cycle.
