Southern Sandspur

　

Common Name: Southern Sandspur (Southern Sandbur) Grassbur

Scientific Name: Cenchrus echinatus L.

Family: Gramineae (Poaceae), Grass Family

History: The name Cenchrus is from the Greek word for millet, cenchros . The Greek species name echinatus means armed with spines.

Field sandbur (grassbur) is a summer annual grassy weed that can be found in home lawns, sports fields, parks and along roadsides. This weed is especially adapted to dry, sandy soils but can be found growing in other types of soils as well. The big problem with this weed is the sharp, spiny burs that are part of the inflorescence. These burs can be painful and are difficult to remove from clothing material. Field sandburs (grassburs) generally start germinating in late spring and will continue to germinate until late summer or early fall months. This weed will continue to grow until the first hard frost or freeze occurs in the fall.
