Viola tricolor

Flowers of Viola tricolor
Viola tricolor is a small plant of creeping and ramping habit, reaching at most 15 cm in height, with flowers about 1.5 cm in diameter. It grows in short grassland on farms and wasteland, chiefly on acid or neutral soils. It is usually found in partial shade. Its root is of the rhizome type with fine rootlets. The stem (acoli stem: which remains flush with the soil and from which leave the leaves and the flowering stalk) is hairless, sometimes downy and is branched. The plant has no leaf rosette at the base, unlike some other violets, such as Viola hirta. Leaves are, on the contrary, alternate. They are stalked at limbus oval, oblong or lanceolate and more or less serrated margins. The stipules are often quite developed, at least those of the upper leaves. These stipules are palm-lined or palmatised.
The flowers are solitary and lateral, hoisted on long peduncles. They appear on aerial stems with more or less long internodes. The sepals are never larger than the corolla. It is 10 to 25 mm long. This corolla can be purple, blue, yellow or white. It can most often be two-tone, yellow and purple. The tricolor shape, yellow, white and purple, is the most sought after.
It flowers from April to September (in the Northern Hemisphere). The plants are hermaphrodite and self-fertile, pollinated by bees.

3-6 hours of sun per day, with protection from intense mid-day sun
