Size and Method of spreading

Wild geranium grows 1 1/2 to 2 feet high with lower leaves and flowering stems growing directing from creeping rhizomes.  Wild geranium is a colonizing ground cover.  Colonizing ground covers produce underground stems that spread out horizontally and shallowly, produce roots and then send up new shoots.  These plants are strong growers and may have the potential to grow aggressively.

Plant Care

Best grown in a moist, well-drained soil in full sun or partial shade.  In hot, dry weather foliage may decline if supplemental water is not supplied.

Disease, pests, and problems

No serious problems, although slugs can be an occasional pest.

Disease, pest, and problem resistance

Resistant to deer and tolerant of black walnut toxicity.

Native geographic location and habitat

Native to Illinois and the Chicago region.  Common in open woodlands.
