Common Dog Violet Viola riviniana
ABOUT
Viola riviniana, commonly known as the Common Dog Violet, is a flowering plant that features a basal rosette of leaves from which its flowers emerge. The leaves are heart-shaped at the base and generally oval, often with serrated edges, and come to a point at the tip. They are medium green in color and have a somewhat glossy finish with a slightly leathery texture. The flowers of the Common Dog Violet typically appear in the Spring and are violet or blue-violet with five petals. The petals are arranged with four facing upwards and one larger petal facing down, which often showcases darker lines or veins that serve as nectar guides for pollinating insects. The lower petal may also have a slight spur. These flowers are unscented, drawing in pollinators primarily through their visual appeal rather than fragrance. As a woodland plant, the Common Dog Violet often grows in clusters, with the flowers rising above the rosette of leaves on slender, upright stalks. The plant's overall form is modest and unassuming, yet it adds a touch of delicate color to the forest floor or garden settings where it is often found.

- Water
Common Dog Violet should be watered regularly, ensuring that the soil remains consistently moist but not waterlogged. During the active growing season in spring and summer, it may require watering once every week with about 1 gallon per square yard, depending on the climate and soil conditions. In the cooler months, watering can be reduced. The amount should be adjusted if rainfall supplements the plant's water needs. It's important to avoid overhead watering to prevent leaf diseases, so water at the base of the plant instead.
- Light
Common Dog Violet thrives best in partial shade to full shade conditions. It should be placed in an area where it can receive filtered sunlight or only a few hours of direct morning sun. Too much direct sunlight can cause the leaves to scorch, while too little can lead to leggy growth.
- Temperature
Common Dog Violet prefers moderate temperatures and can generally survive in USDA zones 4 through 8, withstanding temperatures as low as 25°F and as high as 80°F. The ideal temperature range for this plant tends to be between 60°F and 70°F, which promotes healthy growth and flowering.
- Pruning
Common Dog Violet does not require regular pruning, but deadheading spent flowers can encourage further blooming. Additionally, any dead or damaged leaves should be removed to maintain plant health and appearance. The best time for pruning is after the main flowering period has finished, usually in late spring or early summer.
- Cleaning
As needed
- Soil
Common Dog Violet thrives best in a soil mix that's rich in organic matter, well-draining and moist, with a slightly acidic to neutral pH of 6.0 to 7.0. A combination of garden soil, compost, and perlite or sand would provide the appropriate texture and fertility for healthy growth.
- Repotting
Common Dog Violet, being a hardy perennial, doesn't need frequent repotting. It should be repotted or divided every few years as it outgrows its current space or to rejuvenate the soil.
- Humidity & Misting
Common Dog Violet prefers high humidity environments, similar to its natural woodland habitat. Aim for a humidity level that mimics these conditions without being overly saturated.
- Suitable locations
Indoor
Place in well-lit area, avoid direct sunlight, keep soil moist.
Outdoor
Plant in partial shade, ensure rich, well-drained soil.
Hardiness zone
4-9 USDA
- Life cycle
Common dog violet (Viola riviniana) begins its life cycle as a seed, typically germinating in the spring following dispersal. The seedling develops into a rosette of leaves close to the ground, the juvenile stage of the plant. As it matures, it grows the characteristic heart-shaped leaves and begins vegetative propagation through stolons, which allow the plant to spread. The adult plant flowers from April to June, showing pale violet petals with a white throat, which are pollinated by insects, primarily bees. After pollination, the flowers develop into capsules that eventually split open when ripe, dispersing seeds for the next generation. The common dog violet can also reproduce vegetatively through division, particularly when suitable growing conditions are present.
- Propogation
Propogation time
Spring-Early Summer
Propogation: The common dog violet (Viola riviniana) is typically propagated through seed, with the best time to sow seeds being in late summer or autumn, as they require a period of cold to break dormancy. The most popular method of propagation for this plant is indeed by seed. To propagate common dog violets by seed, collect the seeds from mature pods as they start to split open. Sow the seeds in a cold frame or a sheltered outdoor area in a well-draining soil mixture. Lightly cover the seeds with soil, as they need darkness to germinate, and keep the soil moist but not waterlogged. Germination may take several months, as the seeds undergo a natural stratification process through the winter. Once the seedlings are large enough to handle, transplant them to their desired location in the garden.
