Common cotula

As the name suggests, Cotula australis is a native of Australia and New Zealand, but is a common weed in many parts of the world. It grows in moist, open grassy situations, roadsides, lawns, wall crevices, grassy forests, cultivated areas and orchards. Common cotula is a small prostrate to ascending annual plant, to 10 cm high, while flower-heads are hemispherical in shape, pale-yellow to cream, 4–5 mm diameter, and occur on slender stalks. Flowering typically occurs from winter to spring.
