Description: Cleavers are a weak, taprooted annual with sprawling leafy stems that grows to 20-100 cm tall or long and tends to entangle with other vegetation. Their linear to oblong leaves are round-tipped with a sharp point and are clustered in whorls of 6-8. They are 1-7cm long and have one vein running down the center that has bristles pointing backwards. The hermaphroditic  flowers rise from the axils of leaf whorls in clusters of 3-5. They are 1-2 mm wide and whitish or greenish and bloom between April and June. Petals fused at the base form a short tube that splits into 4 lobes. The fruits of bedstraw are dry 2-lobed burs covered with hooked bristles. 
Habitat: Bedstraw grows from sea level to mid-elevations of the mountains. It is commonly found on beaches, in moist clearings and ditches, and in rich, moist open forests. [1, 4] It tolerates dry soil but scorches quickly in full sun.
Range: Galium aparine and its close relatives are widespread throughout the United States. It does not thrive in hot climates.
