Polish name: field chamomile
Latin name: Anthemis arvensis
Family: the asters Asteraceae (the composites Compositae)
Status in Poland: domesticated since the Bronze Age, very common as a weed of root crops and cereals (mainly winter rye), common also in ruderal places (railway tracks, roadsides, field margins)
Annual plant (therophyte) with spring and winter varieties, with bare or sparsely hairy stems and odorless flower heads.
Aboveground shoots, either bare or hairy, with many shallow furrows.
Leaves without petioles, obelliptic or oblong, pinnate or bipinnate, full-margined or toothed.
Small flower heads with a semicircular involucre with greenish bracts gathered in 2 or 3 rows, unlike chamomile, they are odorless. The torus of each head is filled, conical, with lots of full-margined lanceolate chaffy bracts. Ray florets (usually 10-13 per head) snow-white, female or sterile, serrate at the apex. Disc florets (from 1 to 10,000) golden, bisexual, with an extended base and triangular lobes.
Infructescence in the form of a multitude of achenes placed on the convex torus of the head. Fruits formed from ray florets are flat and slightly bent. Fruits formed from disc florets are characteristically ribbed, obconical, with a pappus at the apex.
It prefers light, acidic and nitrogen-rich soils.
It avoids alkaline soils rich in calcium or gypsum and is an indicator of acidic soils.
Contrary to other cosmetic and dyeing chamomiles, field chamomile was not cultivated intentionally. On the contrary, it was fighted as a weed.
Field chamomile is an ancient healing herb and a natural insecticide.
Field chamomile, growing massively, can provide some benefits to bees, unlike wild chamomile, which is visited almost exclusively by small flies.
It blooms long time, from May to October.
