"Wall barley" (Hordeum murinum) is a common annual grass often found growing in urban environments, such as along walls and roadsides. It's known for its bristly seed heads that can be a nuisance to pets. Think of it as the 'city dweller' of the barley family. Unlike cultivated barley, it's considered a weed in many areas. It spreads quickly and can be difficult to control. Wall barley is a resilient plant that thrives in disturbed habitats.
