Coastal areas of central California (non-native)
Between 6 and 24 inches
Damp, shady sites in woodland; below 1,500 feet
Up to 1.4 inches across; divided into 5 or 7 lobed, wedge-shaped segments
Leaves of geranium potentilloides, an Australian species, are greyish-green in color and divided to about 70 percent of their length into wedge-shaped segments, themselves shallowly lobed. Leaves and stems have a covering of short, bristly hairs. Plants grow upwards and sideways, and can take root from the leaf nodes, to form extensive clumps.
Flowers are borne singly, on stalks a little less than one inch long; they are composed of five green sepals and five white to pale pink petals about a third of an inch in length. Petal tips may be notched or rounded. The flower center contains a group of ten greenish stamens toped by pink anthers.
The plant has limited distribution in the US, restricted to coastal regions of central California, from San Francisco Bay south towards Santa Maria.
