The leaves contain three lobes and each lobe is subdivided again into 3 to 4 lobes.

The inconspicuous flowers are borne in axillary clusters and are surrounded by the stipules. Parsley piert usually springs up in areas where the lawn is closely mowed, spreading in small clusters on lawns.

Parsley-piert is usually an indicator that you are mowing too closely on your lawn along with a nutrient deficiency in your soil which stems from a lack of fertilizer. Although it usually grows as a prostrate weed in turf, in a dense crop it can grow upright, growing 10-20 cm tall. Parsley piert has been known to cause problems in pastures, especially newly sown ones, but also sometimes in established pastures where growth is not dense.
