Where do wild oats grow?

Wild oats are native to the Mediterranean and areas of Europe and Asia, and have since been naturalized in most temperate climates around the world. Wild oats may be found growing in grasslands, crop fields, orchards, vineyards, gardens, roadsides, and other disturbed sites.
