The end shield is usually longer than 2 cm. The diameter of the main screen is 4 to 8 cm. The product of the length times the width of the bracts is on average 13 mm². The pollen grain diameter is larger than 36 µm. The length of the ovary is greater than 1.9 mm.

The flowering period is from June to August. The pollination is done by insects that spread the fruits by the wind.

The number of chromosomes is 2n = 72, less often 36 or 54. The species is octoploid .

As a habitat, it prefers dry and semi- arid grassland , downy oak bushes and forest steppes. It occurs particularly in societies of the associations Seslerio-Festucion pallentis or Geranion sanguinei.

The Hungarian meadow yarrow is a semi-light plant. It also shows warmth, temperate steppe climate and dryness. With regard to the soil, their occurrence is an indication of pronounced nitrogen poverty.
