Corn Marigold - Glebionis segetum

Short to tall greyish hairless plant. Stems erect, branched or unbranched. Leaves oblong, alternate deeply and sharply toothed. Flower heads yellow, 35 to 55 mm, large and Daisy like with strap shaped rays and a flat disk.

Yellow Chamomile (Anthemis (Cota) tinctoria) may be found as a garden escape, but has finely divided lobed leaves.  There are several other yellow flowered daisies that may be naturalised or casual, and specimens should be keyed out using Stace (4th edition)

The leaves are glaucous, slightly toothed to deeply lobed, the upper usually less than halfway to midrib

You must attach images that show sufficient detail for the plant to be identified.

Arable land and preferring light soils, disturbed ground.  Often included in cornfield annual wildflower seed-mixes, and may persist for a while.

June to October

Annual

Locally frequent and widespread in Britain.

Fairly frequent in Leicestershire and Rutland, increasingly as an introduced species; a common constituent of 'cornfield' wildflower seed mixes . In  The Flora of Leicestershire (Primavesi & Evans) it was found in 73 of the 617 tetrads.

In the current checklist (Jeeves 2011) it is listed as Alien (archaeophyte); scarce.

It was on the 2011 VC55 Rare Plant Register (Jeeves, 2011) but is not on the current RPR (Hall & Woodward, 2022); it is listed as 'data deficient' because it is not clear whether records are of introduced/escaped plants or natives.
