Geranium robertianum Linnaeus. Common name: Herb Robert. Phenology: Jun-Oct. Habitat: Rocky woodlands, especially over calcareous rocks. Distribution: NF west to ON, south to e. MD, w. VA, e. WV, c. and e. TN, IN, IL, and MN; Europe, c. Asia, e. Asia, n. Africa, and naturalized elsewhere. Considered by some authors (such as C and G) to be introduced in North America, but apparently native based on its occurrence in remote and high quality natural communities with no other alien species and no likely means of introduction. Reported for AL, (where evidently introduced) by Keener et al. (2024).
