The upper ones encompass the stems. The flower heads have a diameter of 4 centimeters. The ray florets / ray flowers are yellow to dark yellow.

The flowering period extends from June to October.

The number of chromosomes is 2n = 18.

distribution

The herbaceous seed is originally found in Morocco, Algeria, Tunisia, Libya, Spain, France, Italy, Albania, Bosnia-Herzegovina, Greece, Turkey, Cyprus, Syria, Lebanon, Jordan and Israel. It is a neophyte in Madeira, the Azores, southern Africa, Australia, New Zealand, Chile, North America and in some countries in southern, eastern, central and northern Europe .

Past effects on agriculture and present occurrence

The seed bloom occurs in southern, western and central Europe in fields. In the 19th century it was described as the most feared field weed in northern Germany . In some cases, fines were imposed for non-removal.

The wildflower seed caused particularly great problems for agriculture in the Westerwald . From the 16th to the 19th century, travelers and botanists reported several times that it spread over entire regions between Limburg and Hachenburg. The oats in particular could be overgrown across the board. It also appeared frequently in the Marienberg and Höhn areas or in the Siegener Land.

Today the species is going back. It thrives on fresh, nutrient-rich, lime-poor, more or less humus, sandy or pure clay or loam soils. It is a character species of the Spergulo-Chrysanthemetum segetum from the Polygono-Chenopodion association.

use

The seed flower is widely used as an ornamental plant for summer flower beds and as a cut flower. The species has been in culture since 1588 at the latest.
