A self-pollinating annual which occurs as a casual in cereal fields and in all manner of waste places, both as a residue of crops and as a bird-seed alien. Lowland.
T. aestivum is one of the commonest crops of lowland, arable land. It usually occurs as single plants, never persists, and is often ignored by recorders. It was not noted in the wild until 1927; cereal relics were rarely recorded before 1970, but must have been just as frequent then.
Not known as a wild plant; originated in cultivation and now grown in suitable climates throughout the world.
