Geranium robertianum - Herb-Robert geranium
This species is not common in nursery fields, yet. It is becoming
more common along roadsides and in landscapes. So for thoroughness
and comparison to other weeds in this family, I will provide several images
on a single page.
Herb-Robert geranium prefers shady, moist areas. It grows in a small
clump about 12 inches high and wide.
Foliage and stems are very pubescent. Foliage is deeply dissected,
though the leaves are not typical of other geraniums (dovefoot and Carolina
geranium) in this family.
Both stems and foliage have a strong and nauseating smell (in my opinion).
The smell is not disgusting like rotten eggs, but it is more of a strong
chemical smell. It's difficult to describe the scent, but I despise
it and try to avoid it.
Flowers usually occur in pairs.
Flower sepals are very pubescent with long hairs, similar to leaves and
Flowers have 5 petals, 10 stamens, and 1 style (thus the flowers are perfect).
Petals are pink to magenta, with white streaks.
