Wild Oats is one of the two Bellworts in the Garden (the other is the Large-flowered Bellwort, Uvularia grandiflora). Wild Oats is a small native perennial forb rarely over 12 inches high with a single smooth stem that is angled near the upper end and that may make one angled branch in the upper part. The stem is green initially but can become reddish-purplish in the upper part by flowering time. The lower section of the stem is enclosed in a long veined sheath.
Leaves: Unlike it's larger cousin, the leaves clasp but are not pierced by the stem. There can be one or two leaves below any stem branch. They are narrowly to broadly elliptic, smooth, taper to a pointed tip and the margins may have very minute teeth.
Flowers: There is one flower per stem, with 6 pale yellowish to straw colored tepals (petals and sepals combined into a single form) bell-shaped at the base, about one inch long, and drooping. The tepals have rounded to acute tips which flare outward. The outer surface is without hair and usually shows fine veining. The 6 stamens and pistil and style are hidden behind the tepals.
Seed: Fertile flowers produce a 3-winged stalked capsule that has no beaks. Each of the 3 cells in the capsule produces several seeds.
Habitat: Wild Oats grows from slender elongated rhizomes and spreads by underground stolons but the plant usually does not form large clumps like the Large-flowered Bellwort. It grows in woods and clearings where it has dappled sun before tree canopy leafout. Moist to moderate moisture conditions, average soils, partial shade after flowering work well.
Names: The genus Uvularia is derived from the anatomical term uvula, meaning a lobe hanging from the back of a person's palate, and refers to the hanging flowers of this genus. The species sessilifolia is Latin, referring to the sessile (unstalked) leaves. The author name for the plant classification - 'L.' is for Carl Linnaeus (1707-1778), Swedish botanist and the developer of the binomial nomenclature of modern taxonomy.
Above: The inflorescence consists of a single flower, drooping from the top of the stem or from a branch of the stem. The flower stem enlarges slightly at the base of the flower with the ovary protected therein.
Below: Stems have only two branches at most. The lower section of the stem is enclosed in a long veined sheath.
Notes: Eloise Butler recorded planting this species from specimens she brought back to Minneapolis from Winter Pond, Mass. in Sept. 1909. On May 8, 1910 she planted specimens obtained in Osceola, WI. On April 26, 1913 she put in plants from Kelsey's Nursery in North Carolina. The botanical name at that time was usually Oakesia sessilifolia. It is listed on Martha Crone's 1951 census of Garden plants and she planted it in 1952.
Wild Oats is native to most counties of Minnesota from the metro area north except for those in the drier western part of the state. Also to several counties south of the Metro area that border the Mississippi River. In North America it is found from central plains eastward in the U.S. and Canada except for the 3 Canadian Maritime Provinces. This species and U. grandiflora are the only two species of Uvularia found in Minnesota. There are five species of Uvularia in North America.
Lore: Fernald (Ref. #6) reports that Manasseh Cutler in his An Account of Some of the Vegetable Productions Naturally Growing in this Part of America, Botanically Arranged, of 1785, stated that the young shoots could be eaten like asparagus and that the roots could be used in "diet drinks".
Poem: Dora Read Goodale (1866 - 1915) wrote a poem about this flower.
