Habit Plants perennial, acaulescent, stoloniferous, 4–12 cm; stolons green, often rooting at nodes and forming leafy rosettes; rooted rosettes often develop into erect, rhizomatous caudex from which new stolons are produced; rhizome thick, fleshy. Plants perennial, caulescent, not stoloniferous, 2–22 cm.

Discussion

Viola odorata occurs in small colonies; individual plants are interconnected by stolons.

The flowers of Viola odorata are noted for their fragrance; some plants are more fragrant than others. It is native to Eurasia and assumed to be introduced in North America where it is usually found in areas associated with human habitation, including parks, lawns, and roadsides. A substantial industry revolved around the commercial production of violets in England, France, and the United States from prior to 1895 and into the 1900s (R. E. Coombs 2003). Viola odorata is sometimes found in remote locations not easily explained by anthropogenic influence, for example, Clearwater Mountains, Idaho. It is available through the nursery trade and is cultivated as a garden plant and occasionally reported as an escape. Viola odorata is grown in southern France for essential oils used in perfumes, flavorings, and toiletries, and also for the production of the sweet, violet-colored liqueur called parfait amour (V. H. Heywood 1978).

In some populations of Viola beckwithii, the three lower petals are white with a yellow area proximally (V. B. Baird 1942). Leaves have been described as palmately biternate or triternate (L. Abrams and R. S. Ferris 1923–1960, vol. 3), ternately decompound into linear segments (C. L. Hitchcock et al. 1955–1969, vol. 3), palmately three-parted then bipinnately parted into ultimate linear or spatulate segments (P. A. Munz 1959), and palmately about three times three-parted into linear or spatulate-linear segments (W. L. Jepson 1951). Some populations in northern California are nearly or completely glabrous, which M. S. Baker recognized as var. glabrata.

Viola beckwithii is reported to hybridize with V. utahensis (G. Davidse 1976). Observed pollinators of V. beckwithii in Utah include Apis mellifera Linnaeus and Anthophora ursina Cresson (Davidse).

When Cottam described Viola bonnevillensis, he suggested that it could be a hybrid between V. beckwithii and V. utahensis, and G. Davidse (1976) concurred. The type specimen of V. bonnevillensis (Cottam 7067, UT) was examined by R. J. Little. Because no similar forms are known to have been collected since 1939, it is presumed that this taxon is a hybrid.
