Flowering - May - July.

Habitat - Widely cultivated but also planted along roadsides and in disturbed areas. Escaped to waste ground, railroads.

Origin - Developed through cultivation possibly in the Middle East.

Other info. - Triticum is the common "wheat" of cultivation. Many cultivars and subspecies of wheat exist, which is why the plant can be so variable.
The plant can be found scattered throughout Missouri and is commonly planted for erosion control along roadsides, as well as in food plots for animals. Wild plants are not long persistent.
