Geranium dissectum or Cut-leaved Crane's-bill is a plant species of the genus Geranium. It is native to Europe.
It can be found on other continents as well, in some instances as an introduced species. It can be found in North America, where it is known as the cutleaf geranium.
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.

How to get rid of:
It is often more effective with tall herbaceous plants, such as
grasses, and some woody weeds to first slash the area and only
spray the re-growth. Allow 3–4 weeks for new lush growth and
then spray. Most chemicals works best when plants are healthy
and actively growing. By removing dry stems and forcing the plant
to put on new growth the uptake of herbicide will be improved.
This method has the added benefit of opening up the space and
improving access, and can result in less herbicide being used.
