Native Violets For The Garden

Last spring I visited the Smokey Mountain National Park during high wildflower season, and I was struck by all of the unusual, beautiful native violets there.  All had a delicate beauty suited to woodland and shade gardens. I started looking for garden center availability and was struck by the many North American violets available to native gardeners. Most are perennial, but a few survive as spring annuals.

Violets and Wildlife

Overall, our native violets are easy, pretty, and have a place in the garden. In fact, they support wildlife more than most might think. Even the native common blue violet (Viola sororia, Zones 3-9), which gardeners often weed from their beds and lawns, are beautiful and feed the larvae of many species of fritillary butterflies, which are close relatives of monarchs. According to the Xerces Society, a whopping 14 species of greater fritillaries (Speyeria spp.) and 16 species of lesser fritillaries (Bolloria spp.) lay eggs on common violet leaves for their caterpillars to feed upon, develop, and grow.  The fragrant flowers, which have bee nectar guides and are largely pollinated by native bees, are also visited by butterflies. Some native bees are even specialized for Viola flower pollination, such as the violet miner bee (Andrena violae).

Most fritillaries are orange and black. Different species have different pattern markings and ranges.

For these reasons, they are worth leaving alone in lawn areas or other places in the yard. Let them sow and spread freely where they do not compete with other garden plants. If you don’t have common violets in your yard, a good garden variety to try is the beautifully speckled ‘Freckles‘. My mother started it from seed over 25 years ago, and they are still beautiful in the garden! The flowers look very pretty clustered in small bud vases.

Six Beautiful Native Violets for the Garden

Most native violets grow best in fertile, moist soil and partial sun to shade. They also tend to spread, some slowly and others more quickly. They make fine garden perennials, especially for more naturalistic beds. Any exceptions to these rules are noted.

My favorite native violet is the bird’s foot violet, which has large 1.5-inch flowers and fine foliage.

When researching these native violets, I quickly found that all native American violets feed numerous native bees and play larval host to many fritillary species–too many to be mentioned by name. Lots of American fritillaries are threatened or endangered, so maintaining a few native violets in your yard is important! It is also important to source nursery-grown stock or seeds rather than plants collected from the wild. (Click here to learn more about avoiding poached, rare plants.) All seed and plant sources provided here are legitimate.

Labrador violet is often evergreen to semi-evergreen and has purplish-bronze foliage.

Canadian violet (Viola canadensis, Zones 2-8): These hardy perennial violets can reach up to 12 inches and produce lots of white or pale-violet spring flowers that stand tall above the large, heart-shaped leaves. It makes a pleasing native groundcover for moist woodland or shade gardens and is native across much of central and northern North America, extending far into Canada. Expect Canadian violet to self-sow and spread naturally to create a seasonal native groundcover for the shade.

Halberd-leaf yellow violet (Viola hastata, Zones 5-8): Though rarely sold in commerce, at all but the most select native plants sales hosted by native plant societies, Halberd-leaf yellow violet is one of the prettiest of all native woodland violets. Its attractive leaves have silvery markings and sunny yellow flowers are produced in the spring. The woodland native is found in old woods across the eastern coastal United States. If you can find it, grow the 4-8-inch plants in a moist, shaded garden spot.

American dog violet (Viola labradorica, Zones 2-8): Just look at that hardiness zone! This little 3-6-inch violet has native populations that extend into the farthest north reaches of eastern Canada, and it is so lovely. Its low-growing bunches have purplish-bronze, heart-shaped leaves as well as royal-violet-purple flowers in the spring and summer. It is evergreen to semi-evergreen, making it an excellent small-scale groundcover violet for the full sun to partial shade.

Smooth yellow violet is a sweet little yellow-flowered species for shaded gardens.

Bird’s foot violet (Viola pedata, Zones 4-8): I love this unique violet for its fine foliage, which resembles little green bird’s feet, and wide, violet-blue flowers punctuated by orange eyes. They are found in old, established sandy woodlands across eastern North America. Expect the 1.5-inch flowers to appear from spring to midsummer. They will tolerate full to partial sun. Well-drained soil and regular moisture are required. The 3-10-inch plants do not tend to spread.

Prairie violet (Viola pedatifida, Zones 3-7): The sun-loving little prairie violet is native across the prairie lands of Central North America and spreads less aggressively than average violets. Its bright violet-purple flowers look pretty against the delicate, cut-leaf foliage. Unlike most violets, prairie violet will tolerate drier soils. Flowering occurs from mid-spring to early summer. Sometimes it will rebloom later in the season. Plant the 6-inch violets along garden edges where they can slowly self-sow.

Smooth yellow violet (Viola pubescens var. eriocarpa, Zones 3-7): Here is a pretty yellow-flowered violet that grows best in shaded, moist, eastern North American woodlands and gently spreads. Expect it to produce little yellow blooms from mid-spring to summer. Standard Viola pubescens has downy rather than smooth leaves.

Starting Native Violets From Seed

Violet seeds are easily collected or available for sale.

These perennial violets are most often sold from seed, so they are not expensive to grow. Most take a year before flowering from seed. We recommend sowing the seeds in flats of quality potting mix, such as Black Gold Natural & Organic Potting Mix, outdoors in the fall. This method, called moist outdoor seed stratification (click here for stratification guidelines), lets them experience the winter moisture and cold, which many violet seeds need to germinate. When grown by this method, they often sprout in the late winter or spring.

Other Violet Uses

Violets serve other useful purposes in the garden. The flowers are edible, and their fragrant blooms have been used to make perfume over the ages. One common old-fashioned use for the flowers was to candy them. The sugar-crusted violets hold their color, are tasty, and look beautiful for decorating cakes and cookies. (Click here for a good candied-violet recipe.) The flowers can also be used to make a delectable, violet-blue simple syrup that can be added to mixed drinks and lemonade. (Click here for a good violet simple syrup recipe.)

If you have lots of common violets in the yard, try making candied violets.

African Violet Care 101

It is that time of year when I start feeling desperate for flowers. Christmas, with all the decorations and lights, is past, and there are three whole months until April, with its early daffodils and crocus. So what is a perfect, ever-blooming houseplant, to brighten things up at this time of year?  The answer is African violets, and they are easier to grow than most think.

Basic Overview of African Violets

A happy African violet will bloom off and on throughout the year.

African violets (Saintpaulia ionantha) were discovered in 1892, in tropical rain forests in Tanganyika, a small country in eastern Africa. Baron von Saint Paul, the imperial, district governor of the colonized country, found them on the forest floor. He then sent plants and seeds back to his father in Europe, and after passing through several hands they made their way to the Royal Botanical Gardens, Kew, where the first breeding to develop them into houseplants began. They came to the United States in 1894 and by 1946 were so popular that police had to be called in to help with traffic, at the first US National African Violet Show in Atlanta, Georgia. The African Violet Society of America was founded shortly afterward in the same year.

As with any new plant, developing fancy varieties took off quickly, and now with modern breeding, there are fabulous African violets available. Plants range in size from 3 to 16 inches and can have single or double flowers in shades of pink, purple, violet, rose, or white. Some have frilled edges and others are bi-colored, with contrasting edges and centers. Violets that are splashed or speckled with two or more colors are called fantasy types.  Some have variegated leaves with edges, centers, stripes, or spots of white or yellow. Other have leaves with ruffled edges, quilted puffs, or an oak-like shape that add to the beauty of the plants.

Buying African Violets

Fantasy African violets are some of the most spectacular now available.

All garden centers that carry house plants should have a nice African violet selection, but specialty plants must typically be purchased online unless you have a specialty grower nearby. The Violet Barn is an outstanding online nursery for African violets, and, of course, looking at all of their wonderful varieties means that I plan to order some new African violets right away. They have an outstanding selection of unusual trailing varieties, and the fully-double, trailing-pink ‘Cirelda‘ caught my eye. The award-winning, heavy flowering, speckled-violet ‘Rob’s Boolaroo‘ looks unbelievable, as does the pretty pink-flowered ‘Ma’s Debutante‘ with its wonderfully white speckled variegated leaves. I was also attracted to some of the Saintpaulia species, such as Saintpaulia grandifolia, which is elegant and promises prolific violet-blue, butterfly-shaped blooms on long stems. Pretty African violet pots and a bag of Natural & Organic Black Gold African Violet Potting Mix are also on my to-buy list.

Growing Basics for African Violets

African violets require pots with drainage and bottom saucers.

Now, it is true that African violets have a bit of a reputation for being tricky to grow, but with a few instructions, you will easily have beautiful plants that bloom heavily and repeatedly throughout the year.

  1. Light: Providing the right amount and kind of light is important to keep plants blooming. African violets like bright, indirect light, which means putting them in a west- or east-facing window (large north-facing windows also work) and turning them every week for uniform growth. Artificial grow lights can also be used, if they provide consistent, uniform light. Keep the plants no farther than 12 inches away from the light, and provide 12 hours of light a day. If they start having fewer flowers, change the amount of light to 14 hours a day for a few weeks, and then go back to 12 hours. (Note: Grow lights really help in winter when you lack windows. This year, I brought three huge fancy geraniums in for the winter, but I lacked window space for them. I bought grow lights to keep them going until spring, and they are doing very well.)
  2. Water: Proper watering is essential for African violets. They require highly drained soil that is just moist. Room temperature water that is low in minerals is also preferred. When watering, avoid getting water on the leaves, which can cause leaf spots and damage. Instead, either bottom water or water from the top with a narrow-spouted watering can, while being careful to avoid the foliage. Allow water to stand in the bottom saucer for about 1 hour, and then pour it out. Allow the soil to dry out a little before watering again.
  3. Temperature & Humidity: The perfect humidity is 50-60% and temperatures close to 70 degrees F are just right.
  4. Fertilization: Fertilize with a specialty African violet fertilizer, which you can find online. Be sure to follow the manufacturer’s application instructions, because they may vary. I tend to feed them lightly each time I water.
  5. Soil & Drainage: Choose a specialty growing mix, such as Natural & Organic Black Gold African Violet Potting Mix, and always plant African violets in pots with drainage holes and a bottom saucer to catch water. When the plant becomes root bound, upgrade to a pot 1-2 inches larger to encourage new growth.

If your African violet stops blooming, check the number of rows of leaves. If there are 5 or more rows, cut the outside rows of leaves off at the base, back to 2 rows. Each row produces its own flowers, and the crown of leaves can take over the plant.  The most common cause of lack of flowers, however, is not enough light, so move it closer to your light source if plants stop blooming.

With new African violets on the way, I am thinking of places to put mine. My new trailing ‘Cirelda’ will look beautiful in a hanging basket. I cannot wait to see its pretty pink flowers and cascading stems. It should give me gorgeous blooms to brighten the winter and times beyond. For more information, please watch the helpful video below.
