Geranium molle vs. Geranium pyrenaicum

Geranium molle (dove’s-foot crane’s-bill) and Geranium pyrenaicum (hedgerow cranesbill) are so similar that they are almost indistinguishable when not in flower and difficult to distinguish when in flower. The best way to do this is to look at the immature fruit valves.

Geranium molle

Dove’s-foot crane’s-bill or dovesfoot geranium (Geranium molle) grows flat or semi-upright (ascending), as an annual and occasionally as a biennial. Its shoots can reach lengths of up to 30 centimetres. It can flower in Central Europe from April to October.

The petals are pink in colour and only “slightly” longer than the sepals. The valves are hairless and slightly grooved/wavy.
