The native Riddell's Goldenrod is uncommon. It prefers full sun and wet to moist calcareous soil. Habitats include moist prairies, gravelly hillside seeps, fens, and low areas along springs. This perennial is 1–3½' tall with alternate leaves that are lance-shaped and toothless. The lower leaves are up to 8" long and ¾" across on narrowly winged petioles up to 3" long. The upper leaves are up to 4" long and ½" across and often clasp the stem. The stem terminates in a dome-shaped flower panicle, about 2–7" across.

Native Americans used Solidago as in “Sun Medicine” to calm upset stomach, cure wounds, and even for toothaches. The goldenrods were long used topically for wound healing and also to treat tuberculosis, diabetes, enlargement of the liver, gout, hemorrhoids, internal bleeding, asthma, arthritis, colds, flu, kidney stones, bladder and urinary inflammation, allergies, laryngitis and sore throat, mouth ulcers, cuts and abrasions. It has the ability to fight off infection because it has both antimicrobial and anti-inflammatory elements. Reminder: see our Do Not Disturb Notice.
