Parsley-piert could sometimes be confused with:

Parsley-piert, Slender,

This is quite a small, easily passed-by, annual which grows in shallow, stony soil, footpaths and woodland tracks, arable fields and lawns. It is a creeping plant, rarely attaining more than 10cm with really minute, green flowers which have 4 erect sepals and no petals. Blooming from April to October, these tiny flowers have just one stamen and are borne in dense clusters opposite the leaves with triangular-lobed stipules forming a ‘cup’ which surrounds the calyx. The leaves are short-stalked, hairy, fan-shaped with three segments, each deeply-lobed at its tip. This sprawling, downy plant is a native species which is found in its particular habitat throughout Ireland although it is very sparse in the north-west. It belongs to the Rosaceae family. 

I first saw this species in the Burren in 2012 and photographed it in 2014.

Although the leaves could look a little like those of Parsley, the story goes that the name ‘Parsley piert’ comes from the French, perce-pierre, which means a stone breaker or piercer. It does tend to look as if it is emerging from stones. Nicholas Culpeper, 17th century herbalist, prescribed this plant as a winter pickle.
