The terms “viola” and “violet” are often used interchangeably, leading to confusion for gardeners and flower enthusiasts alike. While both plants belong to the same genus, *Viola*, they represent distinct species with noticeable differences in appearance, growth habits, and even their historical significance. Understanding these distinctions is key to appreciating the unique beauty and characteristics of each.
This article aims to clarify the key differences between violas and violets, offering insights that will help you identify them, choose the right plant for your needs, and better understand their place in the botanical world. We will delve into their botanical classifications, visual characteristics, cultivation requirements, and the subtle nuances that set them apart.
Botanical Classification and Taxonomy
Both violas and violets fall under the family Violaceae and the genus *Viola*. This shared ancestry means they share fundamental traits, such as their distinctive five-petaled flowers, often with a spurred petal. However, within this genus, distinct species have evolved, leading to the common names “viola” and “violet” being applied to different groups of plants.
Generally, plants commonly referred to as “violets” are typically species like *Viola odorata* (Sweet Violet) or *Viola sororia* (Common Blue Violet). These are often native to Europe and Asia, or naturalized in North America. They tend to be more robust and have a spreading habit.
Conversely, the plants known as “violas” are often hybrids or specific species cultivated for their smaller size and prolific blooming, such as those derived from *Viola tricolor* (Heartsease). These are frequently the varieties seen in bedding plants and are popular for their compact form and wide range of colors.
Physical Characteristics: Flower Size and Shape
One of the most immediately apparent differences lies in the size of their flowers. Violas typically produce smaller blossoms compared to many of the traditional violets. A viola flower might measure around one to two inches across, while a true violet’s flower can be slightly larger, often exceeding two inches.
The shape of the petals also offers clues. While both have the characteristic five petals, the proportions can differ. Violas often have a more rounded or slightly more symmetrical appearance to their petals. Violets, especially species like *Viola odorata*, can have more elongated or distinctly shaped upper petals.
The “face” of the flower can also be a distinguishing feature. Violas, particularly the pansy relatives (*Viola x wittrockiana*), often have a more pronounced “blotching” or “face” on their lower petals, a characteristic bred for visual appeal. While some violets might have markings, they are generally less prominent than in cultivated violas.
Leaf Structure and Growth Habit
Leaf shape and arrangement provide another point of differentiation. Violets, such as the Common Blue Violet, often have heart-shaped or kidney-shaped leaves that emerge from a basal rosette. These leaves can be quite substantial and may have serrated edges.
Violas, especially those bred for garden bedding, may exhibit more varied leaf shapes, sometimes being more ovate or lanceolate. The leaves are often produced on shorter stems, contributing to a more compact, mounded growth habit. The foliage of violas can also be slightly more delicate in appearance.
The growth habit of violets is often characterized by a creeping or spreading nature, forming dense groundcover. They tend to multiply by runners or rhizomes, colonizing an area over time. Violas, while they can spread, are generally more controlled in their growth, often forming neat clumps that are ideal for borders and containers.
Color Palette and Variety
While both violas and violets come in a spectrum of colors, the range and intensity can differ. Violets are famously known for their rich, deep purples and blues, often with a sweet fragrance. However, they also appear in white, pale lilac, and sometimes pinkish hues.
Violas, especially the cultivated hybrids, boast an astonishingly wide array of colors. This includes vibrant reds, oranges, yellows, blues, purples, whites, and bi-colors, often with striking “faces” or contrasting blotches. This extensive color palette is a result of selective breeding for ornamental purposes.
The intensity and saturation of colors can also be a distinguishing factor. While violets often display a more muted or classic hue, violas can present with more vivid and sometimes neon-like colors, particularly in modern cultivars bred for maximum visual impact in mass plantings.
Fragrance: A Defining Trait
Fragrance is perhaps the most celebrated characteristic of true violets, particularly *Viola odorata*. These flowers emit a sweet, delicate, and unmistakable perfume that has been prized for centuries in perfumery and potpourri. The scent is often strongest in the morning and after rain.
Many violas, especially the smaller bedding varieties, have little to no discernible fragrance. While some hybrids might possess a faint scent, it is generally not as potent or as distinctive as that of the classic sweet violet. This lack of strong fragrance allows their visual appeal to take center stage.
The presence or absence of a strong, sweet scent is a reliable, albeit subjective, way to differentiate between a true violet and a cultivated viola. If the flower is strongly fragrant, it is very likely a violet species.
Cultivation and Growing Conditions
Both violas and violets generally prefer cool to moderate temperatures and can be sensitive to intense heat. They often thrive in partial shade, especially in warmer climates, as full sun can scorch their leaves and reduce blooming. However, the specific requirements can vary by species and cultivar.
Violets, being hardy perennials, are often quite adaptable and can naturalize readily in suitable conditions. They appreciate moist, well-drained soil rich in organic matter and will often spread to fill in garden beds. Their perennial nature means they typically return year after year with minimal fuss.
Violas, particularly the annual or short-lived perennial bedding varieties, are often grown for their prolific, season-long bloom. They require consistent moisture and fertile soil to maintain their vibrant display. Deadheading can encourage more flowers on violas, a practice less common for violets primarily grown for foliage and natural spread.
Hardiness and Perennial Nature
True violet species, like *Viola odorata*, are generally robust perennials, often hardy in USDA zones 4 through 8 or 9. They are well-adapted to their native climates and can withstand considerable cold, often remaining evergreen or semi-evergreen in milder regions.
Many of the plants commonly sold as violas, especially those in the *Viola tricolor* complex and their hybrids (like pansies), are treated as annuals or biennials in many climates. While they might survive a mild winter, they are often not as reliably perennial as true violet species. Gardeners often replant them each season for a fresh display.
The distinction in hardiness is important for long-term garden planning. If you are looking for a plant that will reliably return and spread over years, a true violet species is often a better choice. For seasonal color that can be changed annually, violas are the go-to option.
Historical and Cultural Significance
Violets have a long and rich history in art, literature, and culture. They have been symbols of modesty, faithfulness, and remembrance across various civilizations. The ancient Greeks associated them with love and fertility, while in Victorian times, they symbolized eternal love and loyalty.
The fragrance of the violet was particularly significant, making it a popular ingredient in perfumes and an emblem of delicate beauty. Its presence in poetry and art underscores its enduring appeal as a symbol of gentle charm and quiet devotion.
Violas, while also appreciated for their beauty, have a more recent history tied to horticulture and breeding. Their development, particularly the creation of the large-flowered pansy, is a testament to human ingenuity in selecting and enhancing desirable traits for ornamental gardening. They represent a more modern, vibrant expression of the genus.
Common Examples and Identification
When you encounter a plant known for its strong, sweet scent and typically heart-shaped leaves, often found spreading in shady areas, it’s likely a true violet. Examples include *Viola odorata* (Sweet Violet) with its deep purple, fragrant flowers, and *Viola sororia* (Common Blue Violet), a widespread North American native often found in lawns and woodlands.
Conversely, if you see a compact plant in a nursery or garden center with numerous smaller, often vividly colored flowers, possibly with distinct “faces,” and little to no scent, it’s probably a viola. These are often hybrids like *Viola x wittrockiana* (Pansy) or *Viola cornuta* (Horned Violet) cultivars, bred for their ornamental value and prolific blooming in garden settings.
The key is to observe the combination of flower size, scent, leaf shape, and growth habit. While there are exceptions and many hybrids blur the lines, these characteristics provide a solid framework for distinguishing between the two.
Culinary Uses and Edibility
Both violas and violets can be edible, but their culinary applications and traditions differ. The flowers and leaves of many violet species, particularly *Viola odorata* and *Viola sororia*, are edible and have been used in traditional cuisines and folk remedies.
Sweet violet flowers are often candied for decoration on cakes and desserts, or used to make violet syrup and jelly, prized for their unique flavor and aroma. The leaves, rich in vitamins A and C, can be eaten raw in salads or cooked as a potherb, though they are often quite mild.
While some cultivated violas may also be edible, their primary purpose is ornamental, and they may have been bred for traits other than flavor or nutritional content. It’s always crucial to positively identify any plant before consuming it, and to ensure it hasn’t been treated with pesticides. Stick to wild-foraged or organically grown plants for culinary purposes.
Breeding and Hybridization Differences
The history of breeding for violets and violas has focused on different desired outcomes. For true violets, breeding efforts have often aimed to enhance fragrance, deepen color intensity, or improve disease resistance in desirable species like *Viola odorata*. The focus remains on the classic characteristics of the species.
For violas, particularly those in the pansy and viola groups, hybridization has been driven by an explosion of ornamental traits. Breeders have focused on creating a vast array of colors, patterns, flower sizes, and plant habits suitable for mass bedding, containers, and cut flowers. This has led to a much wider genetic diversity in cultivated violas.
This difference in breeding focus explains the stark contrast in the variety of colors and forms available. The extensive palette of modern violas is a direct result of intensive horticultural breeding programs, whereas true violets often retain more of their natural, species-specific appearances.
Environmental Adaptability
True violets, often being native species, tend to be highly adapted to their specific environmental conditions. For instance, woodland violets are well-suited to dappled shade and moist, humus-rich soils typical of forest floors.
Cultivated violas, while generally preferring cool conditions, are often bred for versatility in garden settings. They can tolerate a wider range of light conditions, from full sun to partial shade, depending on the climate, and are often more forgiving of different soil types, provided they are well-drained.
Their adaptability makes violas excellent choices for a variety of garden situations, from sunny borders to shady nooks. Violets, while hardy, are often best placed where their natural habitat preferences are met for optimal health and spread.
Pest and Disease Susceptibility
Both violas and violets can be susceptible to common garden pests and diseases, but their resilience can vary. Slugs and snails are notorious for damaging the leaves of both, relishing the tender foliage.
Fungal diseases like powdery mildew can affect violas, especially in humid conditions with poor air circulation. Aphids can also be a problem, particularly on new growth. Proper spacing and good garden hygiene are crucial for prevention.
True violets, being wilder and often more robust, might exhibit slightly better natural resistance to certain issues, especially when grown in conditions that mimic their native environment. However, any *Viola* species can be prone to issues if stressed by heat, drought, or inadequate drainage.
Companion Planting Opportunities
Violas and violets can be excellent companions for a variety of garden plants. Their compact size and cool-season blooming make them ideal for interplanting with spring bulbs like tulips and daffodils, providing color as the bulbs finish their display.
They also work well as a groundcover beneath larger shrubs or perennials, suppressing weeds and adding a layer of visual interest. Their low-growing habit doesn’t compete significantly for light or resources with taller plants.
Consider planting violas alongside lettuce or other vegetables, as they are edible and can deter certain pests. Their sweet fragrance can also complement the aromas of herbs planted nearby, creating a more complex sensory garden experience.
The “Pansy” Connection
It is important to note the significant role of the pansy (*Viola x wittrockiana*) in the common understanding of “viola.” Pansies are, in fact, large-flowered hybrids derived from the wild *Viola tricolor* (Heartsease) and other related species. They are a prime example of what is commonly referred to as a viola in modern horticulture.
The term “viola” in a gardening context often encompasses these cultivated pansy varieties, as well as other hybrid violas like the Horned Violet (*Viola cornuta*). This horticultural classification is broader than the strict botanical definition of individual species.
Therefore, when discussing violas versus violets, it’s essential to acknowledge that the term “viola” in common parlance frequently refers to a specific group of cultivated hybrids that are distinct from the species typically called “violets.”
Seasonal Bloom Times
Violas, especially the bedding varieties and pansies, are renowned for their extended blooming periods. They often start flowering in late winter or early spring, continue through the spring, and can persist into early summer, especially in cooler climates.
True violets, such as *Viola odorata*, typically have a more defined blooming season, often in spring, though some may rebloom sporadically. Their flowering is often more in line with natural cycles rather than being bred for continuous ornamental display.
The desire for continuous color in gardens has led to the breeding of violas that can bloom for months. This contrasts with the more ephemeral, though often intensely beautiful, spring display of many wild violet species.
Conclusion: Appreciating the Nuances
While both terms refer to plants within the *Viola* genus, the common usage of “viola” and “violet” highlights distinct groups of plants with differing characteristics. Violets are often associated with species known for their fragrance, heart-shaped leaves, and spreading habit, while violas typically refer to cultivated hybrids bred for prolific, colorful blooms and compact forms.
Recognizing these differences allows for more informed choices in the garden, whether you seek the intoxicating scent of a sweet violet or the vibrant, season-long display of a cultivated viola. Each offers its unique charm and contribution to the world of flowers.
