Corn Marigold is an annual weed of acid arable soils, locally common throughout the UK but decreasing and described as vulnerable by the BSBI.

Corn Marigold was probably introduced and was formerly one of the worst weeds in cornfields. Seed cleaning, liming and herbicides are thought to be responsible for the decline. There were laws in Scotland and Denmark that obliged farmers to root out the weed.

The average number of seeds per flower head is 176 and there is an average of 7 flower heads per plant. Seed numbers on individual plants can be very high, 13,500 seeds have been recorded on one plant. The plant will continue to ripen seeds even when pulled up. The seeds are light and may be distributed by the wind. Seedlings have been raised from the droppings of various birds. It is said the seed can pass through the digestive system of a horse without a loss of vitality.
