USDA Symbol: GAAP2
A weak-stemmed, reclining plant with backward-booked bristles on stems and leaves, and clusters of 1-3 (usually 2) very small white flowers on stalks rising from whorled leaf axils.
The common name is appropriate since the bristles cause the stems, leaves, and fruits to cleave to clothes and the fur of animals. The fact that geese eat the plants accounts for the other common name. The plants are also known as Bedstraws since the pleasant smelling foliage of a yellow-flowered species (G. verum), was used to stuff mattresses in medieval times.
