Geranium robertianum
Also called Robert's Geranium, Mountain Geranium, Robert Geranium
Herb-robert is a small, usually biennial woodland and hedgerow herb of the cranesbill group, widespread across the northern hemisphere. It is a self-seeding weed-like plant, easy to grow in shade or sun wherever soil stays moist.
Geranium robertianum, commonly known as herb-robert or, in North America, as Robert's geranium, is a species of cranesbill that is widespread throughout the northern hemisphere and introduced to some countries in the southern. It is common in woods, hedges, gardens, and on waste ground, and can also be found on shingle beaches and limestone pavements. It is not rare or threatened and in some places it is considered to be invasive.
The main areas of distribution of herb-robert are throughout Europe northwards to the Baltic and eastwards as far as Russia. It also occurs in north Africa and it is considered also to be native in north America, although in some western states it is regarded as a weed.
White-flowered varieties of herb-robert have been cultivated in gardens for centuries. A small-flowered, fragrant white variety, 'Celtic White', is currently a popular garden plant.
