Geranium rotundifolium L., 1753

Geranium rotundifolium (round-leaved crane's-bill), is a species of annual herb in the family Geraniaceae. It is native in temperate climates across much of Europe, northern Africa, and southwestern Asia; its distribution is spreading north, in response to global warming.^[1][2][3] The species favours dry, sandy or stony habitat, including old walls, rail ballast, and building rubble, including in urban areas.^[1]

The basal leaves are simple, 3–6 cm across, broad rounded kidney-shaped, with a shallowly lobed margin; leaves higher up the stem are smaller and more deeply lobed.^[2] The flowering stems can grow to 20 cm tall; both the stems and leaves are hairy with glandular hairs.^[2][4][5] The flowers are small, 10–16 mm diameter, pink, with five petals with a rounded to shallowly two-lobed apex (unlike similar related species, which have a more deeply notched petal apex^[2]). The flowers are visited by sweat bees, Small Carpenter Bees, Myopa, and cabbage butterfly.
