Cardamine hirsuta

Bitter-cresses are common weeds in the area, and are currently flowering. Plants are of various sizes, with flowering stems varying from 1 inch or less in length to over 6 inches. The two species Cardamine hirsuta and Cardamine flexuosa are confusingly similar. On the 10th I photographed a larger plant growing on the edge of a small municipal estate planting. While the photographs were not very successful, and have been deleted, they were sufficient to count stamens (4) and identify that plant as Cardamine hirsuta.
