What is Viola (Violet)?

Violet plants are a group of flowering plants in the genus Viola, which belongs to the Violaceae family. There are around 500 to 600 species within the genus, found in various habitats across the temperate regions of the Northern Hemisphere. Violets are characterized by their heart-shaped or rounded leaves and their five-petaled flowers, which come in a wide range of colors.

Growth habit: Violets typically grow as low-growing, clump-forming herbaceous perennials, although some species can be annuals or small shrubs. They spread by rhizomes or self-seeding and are often found in woodland environments, where they form an attractive ground cover.

Size: Violets vary in size, with most species ranging from 2 to 12 inches (5-30 cm) in height.

Flowers: Violet flowers have five petals, with the lower petal often featuring a spur or small pouch. Some species, like Viola odorata (sweet violet), are fragrant, while others are not.

Blooming season: Violets usually bloom in early spring, but some species can also flower intermittently throughout the summer and fall.

Hardiness: The hardiness of violets varies depending on the species, with many being suitable for USDA hardiness zones 3-9.

Uses: Violets are versatile plants with various uses in the garden, such as ground cover, border planting, rock gardens, and woodland settings. Some species have edible flowers and leaves, which can be used in salads, desserts, and as garnishes.

Deer and rabbit resistance: While no plant is entirely deer or rabbit-proof, violets are not a preferred food source for these animals. They may occasionally graze on them if other food sources are scarce.

Symbol: Violets have a rich history of symbolism, representing modesty, faithfulness, and spiritual wisdom.

What is Special about Violets?

Violets possess several special qualities that make them stand out as valuable and unique additions to gardens:

Early blooming: Violets are among the first flowers to bloom in spring, adding color and life to the garden when many other plants are still dormant.

Fragrance: Some violet species, such as sweet violet (Viola odorata), are known for their delightful fragrance, which can be enjoyed when planted near walkways or seating areas.

Ground cover: Violets make excellent ground cover plants, suppressing weeds and filling gaps in the garden with their dense, low-growing foliage.

Attracting pollinators: Violets provide an essential source of nectar for pollinators like bees, butterflies, and other beneficial insects, contributing to a healthy ecosystem.

Edible and culinary uses: The flowers and leaves of many violet species are edible and can be used in salads, desserts, teas, and as garnishes, adding a touch of color and mild flavor to dishes.

Shade tolerance: Many violet species thrive in partial shade, making them ideal for planting in woodland gardens or shaded areas where other flowering plants may struggle.

Wide variety: With over 500 species in the Viola genus, violets come in a diverse array of colors, sizes, and growth habits, offering gardeners many options to choose from.

These unique qualities make violets a versatile and charming addition to any garden, providing beauty, fragrance, and ecological benefits.

Viola odorata (Sweet Violet): This species is known for its fragrant flowers that come in shades of purple, blue, and white. They are often used in perfumery and as a flavoring in desserts and beverages.

Viola sororia (Common blue violet): Native to North America, this violet has heart-shaped leaves and blue-purple flowers. It is often found in woodlands and meadows and is a popular choice for naturalizing in gardens.

Viola tricolor (Wild pansy or Johny Jump Up): This small, short-lived perennial has tri-colored flowers in shades of purple, yellow, and white. It is often used in wildflower meadows and informal gardens.

Viola x wittrockiana (Garden pansy): These hybrid violets are widely cultivated for their large, showy flowers that come in a wide range of colors and patterns. Garden pansies are often used as annual bedding plants or for container gardening.

Viola cornuta (Horned violet or Tufted violet): This species has long-spurred flowers and blooms in a variety of colors, including blue, purple, yellow, and white. They are often used in rock gardens or as ground cover.

Viola labradorica (Labrador violet or Alpine violet): Native to North America, this violet has small, purple flowers and dark green to purple-tinged leaves. It is an excellent choice for ground cover in woodland gardens or shady borders.

Viola pedata (Bird’s foot violet): This North American native is named for its deeply dissected, bird’s-foot-shaped leaves. It produces large, bi-colored flowers in shades of purple and blue.

Garden Design with Violet Flowers

Incorporating violets into your garden design can add beauty, fragrance, and texture to your landscape. Here are some ideas for using violets in various garden settings:

Woodland gardens: Violets naturally thrive in dappled shade, making them ideal for woodland gardens. Plant them among hostas, ferns, astilbes, and other shade-loving plants to create a lush, layered look.

Ground cover: Use violets as a low-growing ground cover to fill gaps in your garden beds, suppress weeds, and provide a continuous carpet of color during their blooming season.

Borders and edging: Plant violets along garden paths, walkways, or as edging in flower beds. Their low-growing habit and attractive foliage can help define spaces and create a neat, tidy appearance.

Rock garden: Some violet species, like viola cornuta (Horned violet), are well-suited for rock gardens. Plant them in crevices between stones or along the edges of rocky slopes to add color and texture.

Containers and window boxes: Violets, especially garden pansies (Viola x wittrockiana), can be planted in containers, window boxes, or hanging baskets for a pop of color on patios, balconies, or near entryways.

Cottage gardens: Create a romantic, informal look by incorporating violets into a cottage garden design. Plant them among other charming flowering plants like lavender, foxgloves, and delphiniums.

Wildflower meadows: Include violets, such as Viola tricolor (wild pansy), in a wildflower meadow or naturalized area of your garden to support pollinators and add color to the landscape.

Underplanting: Violets can be planted beneath taller plants, like roses or shrubs, to create a layered effect and provide visual interest at the ground level.

When designing a garden with violets, consider the specific growing requirements of the violet species you choose, such as light, moisture, and soil preferences. Additionally, remember that violets often spread by self-seeding or rhizomes, so provide them with enough space to grow and spread as they naturalize in your garden.

Growing Tips

Violas are versatile and low-maintenance plants that can add color and charm to your garden. To successfully grow violas, follow these tips:

Site selection: Choose a planting site with well-draining soil and appropriate light conditions for the specific viola species. Most violas prefer partial shade, but some can tolerate full sun in cooler climates or with sufficient moisture.

Soil preparation: Amend the soil with organic matter, such as compost or well-rotted manure, to improve its fertility and drainage. Violas prefer slightly acidic to neutral soil.

Planting: Space the viola plants according to the recommendations for the specific species, typically 6-12 inches (15-30 cm) apart. Plant them at the same depth they were growing in their nursery pots.

Watering: Keep the soil consistently moist but not waterlogged. Violas prefer evenly moist soil, especially during hot or dry periods. Avoid overhead watering to reduce the risk of fungal diseases.

Mulching: Apply a layer of organic mulch, such as shredded leaves or bark, around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

Fertilizing: Apply a balanced, slow-release fertilizer in spring or early summer, following the package instructions. Over-fertilizing can lead to excessive foliage growth at the expense of flowering.

Deadheading: Remove spent flowers regularly to encourage continuous blooming and maintain a tidy appearance. Allowing some flowers to go to seed for species that set seed can result in naturalizing and self-seeding.

Pruning: Cut back viola plants to rejuvenate them and promote bushier growth.

Winter care: In colder climates, protect perennial violas with a layer of mulch or straw during winter to insulate the plants and help them survive freezing temperatures.

Pest and disease control: Monitor your violas for common pests like Aphids, Slugs and Snails, Spider mites, and diseases like Powdery mildew or leaf spot. Implement appropriate control measures promptly to maintain the health of your plants.

By following these growing tips, you can enjoy the beauty and fragrance of violas in your garden throughout their blooming season.
