One of the most beautiful flowers you can grow in pots or containers is the viola. These small plants make patios, porches, and other small areas more fun with their cute faces and bright colors.
Caring for violas in pots is easy. They will give you months of color if you give them sun, well-drained soil, even moisture, and regular feeding.
This complete guide tells you how to grow violas, how to get them to bloom nonstop, and how to keep them doing well in pots from one season to the next.
An Overview of Violas for Pots
Violas (Viola spp.) are low-growing, mounding plants in the violet family. They produce abundant blooms in shades of purple, yellow, white, red, orange, blue and bicolor.
Common types of violas include
-
Pansies – The most popular viola with large, 2 to 3 inch single or bicolor flowers.
-
Violets – Dainty violas with smaller blooms in purple, blue yellow and white.
-
Johnny Jump Ups – Mini violas with velvety blooms in a mix of hues.
-
Tufted Violas – Mounding plants with 11⁄2 inch flowers above rosettes of foliage.
-
Trailing Violas – Spreading violas perfect for cascading over pot edges.
Violas mostly bloom in early spring and late fall, when it is cool outside. But if you take good care of them, they’ll flower nonstop from spring to fall if you know where they live.
These compact plants thrive in pots 8 to 12 inches wide and 6 to 8 inches deep. Violas also combine beautifully with other container plants.
Choosing the Right Pot for Violas
Picking the proper container sets your violas up for success:
-
Drainage – Be sure pot has holes to prevent soggy soil. Self-watering pots work great.
-
Size – An 8 to 12 inch wide pot fits one viola. Use wider pots for multiple plants.
-
Depth – Minimum of 6 inches deep for the roots. Deeper pots provide insulation.
-
Weight – Heavy pots like clay or concrete offer stability and insulation.
-
Material – Clay, plastic, concrete, wood and metal pots all work.
-
Design – Match your decor, or make a bold statement!

Temperature and Humidity
Violas love the cool weather of early spring, and thrive in milder temperatures from 40℉ to 70℉. Mulch and water will help offset the stress of high temperatures.
With proper care, violas may bloom all summer and most will bloom again in the fall. Or, especially in hot southern climates, take them out and replace them with a different flower during the summer. Then, when fall comes around and the weather gets cooler, put them back in their place.
Types of Violas
Basically, violas and pansies are the same plant, but there are many more types of violas in the same genus that have different names. They include:
- Viola x wittrockiana: This hybrid plant is short-lived and has bigger flowers; it’s also known as the common garden pansy. In colder climates, it’s usually grown as an annual. The plants get about 8 inches tall, and the flowers are 2 to 3 inches across and can be one color or have patterns. This viola is the most popular, and there are dozens of different types of it. It works well in pots and baskets.
- The Viola tricolor plant, which is also known as Johnny-jump-up, is a small one that is related to pansies. Some hybrid pansies will turn back into Johnny-jump-ups when the dropped seeds grow into new plants on their own. It is often used as an edge plant or a filler in the garden.
- This plant, Viola sororia, is commonly known as the “wild blue violet.” It comes from forests and often ends up in gardens and lawns, where it is usually seen as an invasive species—unless it is intentionally grown in native woodland gardens.
- Viola cornuta: This plant is similar to the pansy but has a smaller flower. It is also called the tufted or horned violet. The flowers are 1 1/2 inches across and have two tones. They grow above a rosette of leaves and are 6 to 10 inches tall.
