Sherardia arvensis, an
annual herb originating in Europe, occurs in various places like
wastelands or lawns but is not that easy to find, growing to 30-60cm
in height. Stems are square, with downward setae on the ridges.
Leaves are in whorls of 4-6, in the shape of a narrowly lanceolate,
with sparse, coarse hairs. Flowers are light red or light purple,
and involucres embrace those flowers, which characterize this
species. Corollas measure about 5mm in diameter, about 3mm long, and
have an aperture of four. Bloom time: May-September.
