Wild Oats (genus Avena) are tufted annual grasses that can grow in most soil types with good drainage. In some farming practices, wild oats are considered highly invasive due to its competitive nature to take over. However, this grass type cannot grow in any shade.

Cultivated oats have a narrower, more compact panicle than wild oats, and the non-shattering seed has an unbent lemma bristle that is short enough to sometimes appear absent. Vegetatively, the two are nearly impossible to tell apart, especially when the plants are young.
Wild oat is considered a noxious weed in many parts of the world, having spread from Europe and Central and Southwest Asia to temperate areas worldwide. It was introduced to North America by early European settlers, and is now a common weed of seed crops.
They are known as wild oats or oat-grasses. Those growing alongside cultivated oats in agricultural fields are considered nuisance weeds , as, being grasses like the crop, they are difficult to remove chemically; any standard herbicide that would kill them would also damage the crop.
