Habit Plants perennial, caulescent, not stoloniferous, 3–15 cm. 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.

Leaves

basal and cauline;

basal: 1–3;

stipules linear-lanceolate, margins entire or with glandular processes, apex acuminate;

petiole 1.5–9.7 cm, mostly glabrous;

blade purple-tinted and –veined, broadly reniform to ovate, 0.9–2.4 × 1.2–4 cm, base cordate, margins finely crenate-serrate, eciliate, apex acute to obtuse, surfaces glabrous or sparsely pubescent along veins adaxially;

cauline similar to basal except: stipules ovate to lanceolate, margins entire or shallowly laciniate;

petiole 0.7–5.9 cm, usually glabrous;

blade 0.8–2.1 × 1.2–3.1 cm.

basal (and from stolons), 5–10, ascending to erect;

stipules lanceolate to linear-lanceolate, margins fimbriate, projections gland-tipped, apex acute;

petiole 2–17 cm, puberulent;

blade unlobed, ovate to orbiculate, 1.5–7 × 1.5–5 cm, base cordate, margins crenate, ciliate, apex obtuse to rounded, surfaces puberulent.

Peduncles

1.8–7.1 cm, usually glabrous.

4–15 cm, puberulent.

Flowers

sepals lanceolate, margins eciliate, auricles 0.5–1.5 mm;

petals soft reddish violet on both surfaces, all with yellow area basally, lower 3 dark violet-veined, lateral 2 bearded, lowest with white around yellow area, 10–15 mm, spur yellow, gibbous, 0.5–2 mm;

style head bearded; cleistogamous flowers axillary.

sepals narrow to broadly lanceolate, margins ciliate, auricles 3–4 mm;

petals deep to pale blue-violet, pale blue, or white on both surfaces, usually white basally, lateral 2 sparsely to densely bearded, lowest usually purple-veined, 12–22 mm, spur usually same color as petals, elongated, 5–7 mm;

style head beardless; cleistogamous flowers on prostrate or ascending peduncles.

Capsules

± spherical, 5–9 mm, glabrous.

sometimes purple-flecked, ovoid, 5–8 mm, puberulent.

Seeds

dark brown to brownish purple, 2.5–3 mm.

brown, 3–4 mm.

Discussion

Viola flettii is endemic to the Olympic Mountains of northwestern Washington. C. S. McCreary (2005) noted that although morphologically and ecologically distinct, V. cuneata, V. flettii, and V. ocellata are closely related.

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).
