SIOUX FALLS, S.D. (AP) -- After reporters pointed out that wild marijuana, commonly called ditch weed, was growing on the lawn at the federal courthouse in Sioux Falls, the greenery was eliminated.

City officials and a developer said seeds in dirt brought in for construction must have sprouted.

KSFY-TV in Sioux Falls had it tested to be sure it was ditch weed and brought it to the attention of federal officials last week. None wanted to comment.

Low-grade, wild marijuana was initially grown as hemp to make rope in World War II. But it contains a small amount of the ingredient that makes marijuana smokers high.
