Renewed birds

The bird renouée or Polygonum aviculare is an annual herbaceous plant belonging to the family Polygonaceae. It is native to the Northern Hemisphere and grows a little wherever man lives: near houses, in gardens, in fields? Invasive and resistant, it can also push in the wheels, on the edge of sidewalks? A number of subspecies are distinguished, including bird renouée, field renouée and gravel renouée. Generally speaking, this plant is very polymorphic. It has many small stems that can be spread to the ground or reach a height of 60 cm. Its leaves are usually alternate, elliptical, lanceolate and have a green to green-grey blade. It gives white or pink flowers that can be solitary or grouped by 2 or 4.
