Small wildflowers grow in the riparian area surrounding the pond. Some are invisible to the casual observer because of their small stature, or because they are hidden by the many taller grasses and reeds.
One of these tiny weedy wildflowers is Common Mallow Malva neglecta, with 5 petals of palest pink with stronger pink stripes.
The leaves resemble geraniums but the two families have different reproductive structures.
Mallow is also called 'Cheeseweed' since each seed looks like a miniature wheel of cheese.
