| Distribution | Primarily Mountains and Piedmont; disjunct to Currituck and Dare counties. The gap in the Piedmont is probably an artifact of collecting.
Native of Europe and western Asia; in N.A. much of southern Canada and the U.S., but absent from much of the northern Midwestern Plains, southern Rocky Mountains, and arid Southwest. | |
| Abundance | Fairly common in the Mountains, mostly uncommon to infrequent in the Piedmont, but rare in the outer Coastal Plain. | |
| Habitat | Dry to moist roadsides, creek banks, highway rest areas, lawn weed, campus weed, hiking trail. | |
| Phenology | Flowering and fruiting April-August. | |
| Identification | Like some other alien Geraniums, this one's leaf blades are generally round in outline and highly dissected, but the segments are wider than with the other species. The sepals have a short blunt tip (vs. thin mucro or awn). The stem hairs are a mixture of long villous non-glandular hairs and short glandular hairs, versus both kinds short glandular in G. pusillum. This species has deeply notched or cleft petals at the tip, giving a flower the look of having 10 petals instead of 5. | |
