Corn marigold (Glebionis segetum) is an annual species, typically reaching 20 to 50 cm in height. Its slender stems carry narrow leaves and bear single, cheerful yellow daisy‑type blooms from early summer onwards. The petals form a sunny halo around a central disc, and each bloom lasts several days, replenished by successive flowering over the season. As an annual, its lifecycle completes in one year: after flowering and seed set, the plant dies, leaving seed to regenerate the next season.
In the wild historically, corn marigold grew alongside cereal crops, carried in seed mixes or via spilt grain, its decline largely parallels more intensive seed cleaning and modern agricultural practices. The seed is suited to well-drained soils in full sun, with less tolerance for heavy shade or overly rich soils. As its seed is small and relatively short-lived in the soil, it responds best when sown freshly in open, bare or lightly disturbed ground. In meadow, verge or wildflower schemes, it lends early vertical accent and a flush of yellow before taller perennials dominate.
