Geranium columbinum, common name long-stalked crane's-bill or longstalk cranesbill, is a herbaceous annual plant in the family Geraniaceae.
Geranium columbinum reaches on average 15–30 centimetres (5.9–11.8 in) in height, with a maximum of 60 centimetres (24 in). The stem is more or less erect, hairy and quite branched. The leaves are opposite, approximately pentagonal and palmate and the leaf lobes have two to three deep cuts making it similar in shape to a pigeon's foot (hence the Latin epithet columbinus).
The flowers are pink to purple, 15–20 millimetres (0.59–0.79 in) in size, with five obovate-heart-shaped petals as long as the sepals. The petals are 7–9 mm long, with distinctive veining. The flowering period extends from March to September. The flowers are hermaphrodite and pollinated by insects (entomogamy).

How to get rid of:
Annual grasses should be high slashed (10 cm above ground)
before seed heads start to develop, typically in late winter and may
require follow-up slashing after 4-6 weeks. As they are annuals,
preventing the production of seed will ensure their seedbank will
diminish with time.
Perennial grasses can be slashed at any time of year, however best
results will be obtained during winter and spring.
