Other names and notes
(Spotted Geranium, Crane's-bill) An erect perennial of the open woods, it reaches up to 2 feet in height. Leaves: The large palmately-divided basal leaves have 5 to 7 lobes and are irregularly cleft and have long stalks on which are white hairs. There is also one pair of smaller leaves on short stalks on the flowering stem, which grows directly from the root. Flowers: The flower color will vary from a rose-purple when growing in full shade to almost white (usually when exposed to much sun). Flowers are 5-part, 1 to 1 1/2" wide and appear on stalked loose clusters above the leaves. Petals have a deeper color veining. Pedicels (flower stalks) are hairy and each division of the cluster has small linear bracts. Flowers have ten stamens with light brown anthers, several styles, 5 petals and 5 sepals that are shorter than the petals. Fruit: An erect beak-like seed capsule, covered with hair, develops at maturity. The capsule has five cells, each containing one seed and when mature, the outer carpels of the capsule curl backward to expose the seeds. Found throughout the Woodland Garden, usually in large swaths. It grows from rhizomes. Mature rhizomes are 2 to 4 inches long with branching for new growth. See Eloise Butler's notes below.

Notes: This plant is indigenous to the Garden area. Eloise Butler catalogued it on May 25, 1907. It is native to the woods of Minnesota, particularly the counties of the east half and central parts of the state. In North America it is found from the mid-continent eastward, except Florida.

Eloise Butler wrote: "Few are unable to name the Wild Geranium when they observe the form of the leaf, the flower cluster, and the flower. This geranium enlivens large expanses of woodlands with its purplish flowers. The significance of another name - cranesbill - is seen when the blossom goes to seed, forming a birdlike beak, from the base of which uncurl fine little seed-like fruits." Published June 4, 1911, Sunday Minneapolis Tribune

Medicinal uses: The root of the plant contain tannic and gallic acid and was used in dried and powdered form as an astringent and styptic. When dried the white internal parts of the root turn purple, have a strong astringent taste without odor. Densmore (Ref. 5) in her study of the Minnesota Chippewa reports usage of the dried and powdered root for treating mouth sores, especially effective for children. Hutchins (Ref. #12) reports many other uses.
