Parsley piert plants looks a lot like the Italian Parsley used in the kitchen. Each leaf is made of 3 parts, which are also divided at the tip.
It is typically sprawled, but can grow upright. It is typically found in turf, or new and less dense pasture. Parsley piert tends to establish in autumn and seed in spring.
Parsley piert is a very low growing weed which survives low mowing heights, and as it is herbicide-tolerant will take over where other weeds have been sprayed out.
It is sometimes confused with Onehunga weed but can be distinguised due to the leaf shape.
