Key Takeaways

  • Choose the appropriate viola variety for the desired arrangement and appearance
  • Carefully harvest and handle viola stems to maintain their delicate structure
  • Proper maintenance and hydration in a vase will extend the lifespan of viola flowers

Choosing the Right Viola Variety

When it comes to selecting the perfect viola variety for your vase, it’s essential to consider the differences between perennials and annuals. In this section, we will explore these differences and introduce you to some popular viola varieties.

Perennials vs Annuals

Perennials are plants that live and bloom for more than two years. Some popular perennial violas include Viola tricolor and Viola cornuta. These varieties return and bloom year after year, making them an excellent choice for long-lasting floral arrangements.

Viola tricolor, often referred to as Johnny-Jump-Ups, are petite flowers with vibrant tricolor patterns, combining purple, yellow, and white hues. Viola cornuta, commonly known as horned violets, have delicate, slightly larger flowers that come in various shades of blue, purple, and yellow.

On the other hand, annuals are plants that complete their life cycle within one growing season. One popular annual viola is Viola x wittrockiana, also known as the pansy. Despite their shorter lifespan, pansies produce larger and more colorful blooms in comparison to their perennial counterparts. Pansies come in a wide range of colors, from traditional solid hues to multicolored varieties.

When selecting a viola variety for your vase, consider the following factors: longevity, bloom size, and color preference. Perennials like Viola tricolor and Viola cornuta offer long-lasting beauty, while annuals like Viola x wittrockiana provide bold and vibrant blooms.

Preparing the Soil and Seeds

Soil Type and Preparation

Violas thrive in well-draining, slightly acidic soil with a pH range of 6.0-6.5. Before planting, mix in plenty of compost and organic matter to enrich the soil, ensuring that nutrients are readily available for your viola plants. You can also add a slow-release granular fertilizer to provide additional sustenance as needed (source).

To improve drainage and aeration, loosen the soil to a depth of 8 inches. Adding mulch is advised once the viola seedlings are established, as this helps retain moisture and suppress weeds.

Selecting and Planting the Seeds

When choosing viola seeds, look for varieties that suit your climate and desired color palette. You can find viola seeds in various patterns and shades, ranging from vibrant to pastel colors.

To plant the viola seeds, follow these steps:

  1. Sow the seeds in a tray or pot, ensuring there is ample spacing between them.
  2. Bury the seeds about 1/8 inch deep, as they require darkness to germinate (source).
  3. Maintain a cool temperature (approximately 60°F) and consistent moisture levels to support a healthy germination process.

Once the viola seedlings have developed two sets of true leaves, you can transplant them into their final growing location or a larger pot. Remember that proper drainage and soil pH are crucial to ensure the successful growth and flowering of your violas in a vase.

Selecting the Proper Location

Sunlight Requirements

Violas thrive in environments with partial sun to partial shade. They can tolerate full sun, but they prefer some protection during the hottest parts of the day, especially in warmer climates. In north america, aim for a spot that gets morning sun and afternoon shade, or an area with dappled sunlight throughout the day. This will help ensure proper care of your violas in a vase.

Climate and Temperature Considerations

Violas can grow in a wide range of climates, but they are sensitive to extreme heat and cold. They perform best in temperatures ranging from 40°F to 70°F (4°C to 21°C). In north america, this means that violas can be grown successfully in USDA hardiness zones 3 through 9.

To maintain a comfortable temperature for your violas in a vase, keep them away from drafty windows, heating vents, or air conditioning units. Monitor the temperature around the vase to ensure it stays within the optimal range for the health of the flowers. If you live in an area with particularly hot summers, consider placing the violas in a cooler, shaded area during the peak afternoon heat to help them withstand the higher temperatures.

Watering and Fertilizing Violas

Proper Watering Techniques

Violas thrive in a consistently moist environment. To ensure they receive adequate water, use a drip irrigation system or manually water them with a gentle stream of water. Be sure to water them at the base of the plant and avoid getting the leaves and flowers wet, as this can lead to disease.

Check the soil around your violas regularly by inserting your finger about an inch into the soil. If the soil feels dry at this depth, it’s time to water your plants. In general, violas need to be watered about once or twice a week, depending on the weather and soil conditions.

Fertilizer Recommendations

To encourage healthy growth and abundant blooming, feed your violas with a well-balanced, slow-release fertilizer. A good formula for these plants is a 10-10-10 ratio (nitrogen, phosphorus, and potassium). You can apply the fertilizer to the soil around the plant at the beginning of the growing season, and then again midway through the season.

In addition, using a liquid fertilizer diluted with water every two weeks can provide additional nutrients for your violas. Be sure to follow the application instructions on the fertilizer label and avoid over-fertilizing, as this can lead to excess foliage growth and fewer flowers.

By properly watering and fertilizing your violas, you can help them maintain a healthy, vibrant appearance in your vase throughout their blooming season.

Violas in Containers

Violas are a charming addition to any garden or indoor space, and growing them in containers is a great way to control their environment more effectively. Choosing the right containers and planting methods will ensure your violas remain healthy and vibrant.


When choosing a container for your violas, consider how much space is available and which materials will best suit your needs. There are various types of containers available, such as plastic, ceramic, or terracotta pots. Generally, a container that is about 8-12 inches deep and wide is an ideal size for violas. Make sure the container has adequate drainage holes to prevent water from pooling, which can lead to root rot.

Selecting a high-quality potting soil is important for the health of your violas. A mix containing plenty of organic matter and good drainage capacity will provide your violas with the nutrients they need to prosper. Additionally, adding a slow-release granular fertilizer to the mix can promote strong root development and abundant flowering.


To sow viola seeds, follow these steps:

  1. Prepare the container with a layer of gravel or small stones at the bottom for improved drainage.
  2. Fill the container with the potting soil mix until about 1 inch below the rim.
  3. Gently press viola seeds onto the soil surface, spacing them about 2 inches apart.
  4. Lightly cover the seeds with approximately 1/8 inch of soil, as they need some light to germinate.
  5. Water the soil gently but thoroughly, allowing the excess water to drain through the holes.

Violas prefer cool conditions, so it’s best to maintain a soil and air temperature of around 60°F for optimal germination and growth. Once the seedlings are large enough to handle, you can transplant them into larger containers if necessary. Remember to harden off your viola plants by gradually exposing them to outdoor conditions before settling on their permanent location.

Caring for violas in containers is relatively simple, and with proper planning and planting techniques, you will enjoy their unique beauty in your living space for an extended period.

Viola Care and Maintenance

Caring for violas in a vase involves consistent monitoring and timely actions to ensure their healthy growth. There are a few essential maintenance tasks that play a significant role in your violas’ overall appearance and vigor.

Deadheading and Pruning the Plants

Deadheading is a crucial aspect of maintaining your violas. Regularly removing wilted or faded flowers encourages the plants to produce more blooms over an extended period. To deadhead violas, gently snip off the spent blossoms at the base of the flower stem, taking care not to damage the nearby leaves or buds.

Pruning isn’t as frequent as deadheading but is still necessary to keep your violas in good shape and prevent overcrowding. Trim back any leggy, overgrown, or unhealthy stems, ensuring even growth, and a neat appearance.

Pest and Disease Control

Pests like slugs, snails, and aphids can damage your violas. To prevent a slug or snail invasion, remove any hiding places (such as plant debris or mulch) and use natural repellents like crushed eggshells or organic slug bait to keep them in check. If you notice aphids on your violas, you can keep their population under control by spraying your plants with a strong jet of water or using insecticidal soap to eliminate them.

Violas can also fall victim to diseases, such as root rot and leaf spot. Regularly check the leaves and roots for any signs of infection or decay. If you find any concerning symptoms, promptly remove the affected areas. To prevent waterlogged soil and root rot, ensure proper drainage for your violas by putting gravel or small stones at the bottom of the vase. Prevent leaf spot by keeping your violas clean and free of debris, allowing proper air circulation and avoiding overhead watering that leads to excessive moisture on the leaves.

By diligently following these care and maintenance tips, your violas are more likely to thrive and exhibit their vibrant beauty in your vase.

Caring for Violas Outdoors

Caring for violas outdoors requires attention to their planting location, soil quality, and protection from pests. By following these guidelines, your violas will thrive and add color to your landscape.

Firstly, it’s essential to choose a suitable location for the violas. They love the sun but not the heat, so plant them in areas where they are protected from the mid-afternoon sun. This is especially important for gardeners in warmer regions, as defined by the USDA zones.

The soil quality for your violas is equally crucial. They require rich soil that drains freely, ensuring their roots can access plenty of nutrients and water. If you’re growing violas alongside vegetables in your garden, it is crucial to provide similarly rich soil that benefits both types of plants.

To start growing violas, you can either plant them indoors from seeds 8 to 12 weeks before the last frost or sow them directly into your garden. However, many gardeners recommend the indoor method as it tends to be more successful.

Once your violas are established outdoors, fertilizing is essential for promoting bloom. Use a slow-release fertilizer during the spring and late summer months, as it helps your violas bloom in the fall. Taking care of violas also involves regular monitoring for pest infestations. Some common garden insect pests affecting violas are mealybugs and aphids. Treat these pests promptly to keep your violas healthy and free from damage.

In conclusion, by providing the right location, soil, and care, you can ensure the successful growth of your violas outdoors. The addition of these beautiful flowers will enhance your landscape and complement vegetable gardens, creating an attractive and functional outdoor space.

Using Violas as Cut Flowers

Violas make beautiful cut flowers for any vase arrangement. They offer a range of colors and delicate patterns that can brighten up any space. To enjoy the captivating beauty of violas in a vase, follow these simple care tips.

Choosing the Best Blooms

To get the most out of your violas, make sure to choose the longest and strongest stems from your garden. Look for flowers that have just begun to open, as they will have the most extended flowering time in your vase.

Once you have selected and cut your violas, remember to:

  • Trim the stems: Before placing your violas in a vase, give them a fresh cut at a 45-degree angle to stimulate water uptake.
  • Remove excess foliage: Take off any leaves below the waterline that could decompose and lead to bacterial growth in the vase water.
  • Use clean water: Fill your vase with clean, room temperature water to help your violas last longer.
  • Add flower food: You can use a commercial flower preservative or create a DIY solution with 2 tbsp of sugar, 1 tbsp of white vinegar, and 1 quart of water. This mixture can help extend the life of your cut violas.
  • Change water regularly: Every 2-3 days, replace the water in your vase to keep it fresh and free of bacteria. Re-cut the stems and add more flower food when necessary.

In addition to these care measures, make sure to position your vase of violas away from direct sunlight, drafts, or sources of heat, as these factors can shorten the lifespan of cut flowers.

By following these simple guidelines, you can enjoy the beauty and charm of violas as cut flowers in your home or office.

Violas as Ground Cover

Violas make excellent ground cover plants due to their low-growing and spreading habit. They thrive in various conditions and provide a beautiful carpet of color in your garden. Planting violas as ground cover can be a great way to add interest to your landscape and fill in empty spaces, especially under shrubs and taller plants.

To establish violas as ground cover, choose an area with well-drained soil and partial shade. Avoid areas with constant direct sunlight, as violas prefer cooler conditions and can suffer in extreme heat. A spot with morning sun and afternoon shade would be ideal for these plants.

When planting violas, space them about 6 to 8 inches apart so they can spread and cover the ground efficiently. They will quickly grow and start forming clumps, filling in the gaps between plants. Water your violas regularly, keeping the soil evenly moist but not soggy, to help them establish and grow healthily.

Proper maintenance is essential for your violas to serve as an effective ground cover. Deadhead spent flowers to promote continuous blooming and keep the plants looking fresh. In addition, it’s a good idea to prune or trim your violas in early spring to encourage bushier growth and prevent them from becoming too leggy or untidy.

If you’re looking to create a living carpet of color in your garden, violas are an excellent choice for ground cover. They’re low-maintenance, versatile, and provide a charming and vibrant touch to your outdoor space.

Violas in the Garden

Growing violas in your garden can be a delightful experience, as they are easy to grow and maintain. These cool-season plants thrive well in full sunlight, so it is essential to choose a location where they can receive plenty of light 1.
