Today a photograph of Pelitory of the Wall (Parietaria officinalis), taken by Elodie den Otter, outside of a yoga studio in Amsterdam. This is a really useful little herb which really is well adapted to growing out of wall cracks and between paving stones. It is useful as a urinary system tonic and has many historic and contemporary applications. Please see my post on day 63 about sister herb, Pensylvania Pelitory, for further information about the two plants.
