ABOUT
The common name for Viola sororia is the common blue violet. It's a perennial plant that typically bears heart-shaped leaves that are broad and somewhat rounded, often with a fine layer of hair-like structures. The leaves grow in a basal arrangement, which means they emerge from the base of the plant on their individual stems. The flower color of the common blue violet usually ranges from blue to violet, though some may present white with streaks of violet. The flowers are delicate, with five petals; the lower petal often has vein-like markings and may have a slight spur at the back. This plant blooms in early spring and often into summer, flaunting its brightly colored flowers that attract various pollinators. After flowering, it produces inconspicuous green seed capsules that can eject seeds when ripe. The overall look of the plant is lush and the flowers have a subtle charm, making it a favorite in wildflower gardens and naturalized areas. The common blue violet is also known for its resilience and ability to spread, forming attractive ground cover in suitable environments.

Water
The common blue violet, Viola sororia, prefers consistently moist soil and should not be allowed to dry out completely. It is generally recommended to water the plant once a week, providing it with about 1 inch of water at each watering session. The actual frequency can vary depending on climate conditions and soil type; in hotter, dryer periods, it might require watering twice a week. It's best to water the plant deeply rather than a light sprinkle, to encourage deep root growth. Use room temperature water to avoid shocking the plant's roots.
Light
Common blue violets thrive in partially shaded conditions; they do well under dappled sunlight or in an area that receives morning sun and afternoon shade. Avoid placing them in full sun, which can be too intense and may scorch the foliage. A north-facing or east-facing spot that gets filtered light is ideal for promoting the best growth and flowering.
Temperature
Common blue violets are hardy and able to withstand a temperature range from as low as 20°F to around 85°F. They prefer cooler conditions and perform best when temperatures are between 60°F and 75°F. Prolonged exposure to temperatures outside of this range, especially extreme heat, can stress the plant and impact its health and blooming.
Pruning
Pruning common blue violets is typically done to remove dead or yellowing leaves and to maintain a tidy appearance. Light pruning can be performed at any time during the growing season to remove spent flowers and encourage bushier growth. Intensive pruning should be done in late fall or early spring to prepare the plant for new growth.
Cleaning
As needed
Soil
The Common Blue Violet (Viola sororia) thrives best in a soil mix that is rich, moist, and well-draining. A good recipe for soil mix would be a blend of loamy garden soil, peat moss, and compost, which helps ensure both moisture retention and proper drainage. The ideal soil pH for the Common Blue Violet should be slightly acidic to neutral, ranging from 6.0 to 7.0.
Repotting
The Common Blue Violet typically does not need to be repotted often as it's a perennial that can spread through self-seeding. However, if grown in a container, it may benefit from repotting every 2-3 years to refresh the soil and accommodate growth.
Humidity & Misting
The Common Blue Violet prefers a moderate humidity level but is quite adaptable to different humidity conditions as it is a native woodland plant. It is tolerant of the average humidity found in most homes and gardens.
Suitable locations
Indoor
Provide bright, indirect light and keep soil moist for indoor Common Blue Violets.
Outdoor
Plant in partial shade with rich, moist soil for outdoor Common Blue Violets.
Hardiness zone
3-9 USDA
Life cycle
Viola sororia, commonly known as the "Common Blue Violet," begins its life cycle as a seed, typically germinating in the cool, moist conditions of late winter to early spring. Upon germination, the plant develops a root system and a rosette of heart-shaped leaves close to the ground. As the plant matures, it sends up stems bearing the distinctive purple flowers in the spring; these flowers can self-pollinate or be cross-pollinated by insects. After pollination, the flowers produce fruits that are technically capsules containing seeds, which are dispersed by various means, such as water, animals, or mechanical forces. In addition to sexual reproduction, Viola sororia can propagate vegetatively through stolons, allowing for clonal colonies to form. The plant enters a period of dormancy during the colder months, but it is a perennial and will re-emerge from the rootstock with the arrival of favorable growing conditions in the next season.
Propogation
Propogation time
Spring to summer
The common blue violet, Viola sororia, is often propagated by seed, as it's the most popular method. Seeds can be collected from mature plants after flowering and seed capsule formation, usually in late spring to early summer. Seeds should be spread on the surface of a well-drained seed starting mix and lightly pressed into the soil. They require darkness to germinate, so it is crucial to cover them with a thin layer of soil or fine sphagnum moss. Ideal germination temperatures are between 65 and 70 degrees Fahrenheit (18-21 degrees Celsius). Seedlings usually emerge in two to four weeks, after which they should be gradually acclimated to outdoor conditions before being transplanted to their final location in the garden. Care must be taken to keep the soil consistently moist but not waterlogged during germination and early growth.
