Introduction
There is a special kind of satisfaction that comes from seeing a garden path perfectly lined with neat, colorful blooms or a window box that looks lush and full from the very first month. Low growing begonias are the secret to achieving this look with ease. These compact plants offer a wealth of color and interesting foliage without ever becoming overgrown or unruly. Whether you are looking to fill a small gap in a shaded border or want a reliable performer for your favorite patio pots, these versatile plants are a delightful choice for any gardener.
At Longfield Gardens, we enjoy helping you find the right plants to make your outdoor spaces feel like a personal retreat. This guide is designed for home gardeners who want to understand the different types of low growing begonias and how to use them effectively. We will cover everything from selecting the best varieties for your climate to the simple steps for planting and daily care. By choosing the right compact begonia, you can enjoy a season full of effortless beauty and vibrant flowers.
Why Choose Low Growing Begonias?
Low growing begonias are often the unsung heroes of the shade garden. While taller perennials might grab attention with their height, compact begonias provide the essential "groundwork" that makes a landscape feel finished. They typically reach heights of 6 to 12 inches, making them ideal for the front of a flower bed or as a dense filler in mixed containers.
One of the greatest benefits of these plants is their "set it and forget it" nature. Unlike some high-maintenance annuals that require constant pinching or deadheading to stay tidy, most low growing varieties naturally maintain a mounded, bushy shape. They are also incredibly generous with their blooms. Once they start flowering in early summer, they usually continue right up until the first frost.
These plants are also excellent problem-solvers for tricky spots. If you have a north-facing porch or a garden bed tucked under a large tree, you know how hard it can be to find bright color that thrives in low light. Begonias are perfectly adapted to these conditions. Their waxy or textured leaves are efficient at capturing what light is available, and their succulent stems store enough moisture to keep them resilient through warm summer afternoons.
Popular Types of Compact Begonias
Not all begonias are the same, and understanding the differences between the common types will help you pick the best one for your specific garden goals. Most low growing varieties fall into three main categories: wax begonias, tuberous begonias, and foliage-focused types like Rex begonias.
Wax Begonias (Semperflorens)
Wax begonias are the quintessential bedding plant. They are named for their glossy, waxy leaves, which can be either bright green or a deep, bronzy red. These plants are exceptionally tough and can handle a bit more sun than their relatives, provided they have enough water. They usually stay quite low, forming dense mounds that are perfect for creating a "ribbon" of color along a walkway.
Non-Stop Tuberous Begonias
If you want the largest flowers possible on a small plant, the "Non-Stop" series is a fantastic option. These are tuberous begonias specifically bred to stay compact while producing big, double blooms that look like roses or camellias. We often recommend these for window boxes or hanging baskets because they provide high-impact color without the long, trailing stems that can sometimes get tangled or damaged by wind.
Dwarf Rex and Rhizomatous Begonias
While many people grow begonias for the flowers, these types are grown for their spectacular leaves. Dwarf Rex begonias offer swirls of silver, purple, pink, and burgundy. They stay very low to the ground and are excellent for adding texture to a shaded corner. Because they stay small, they are also a favorite for indoor dish gardens or small decorative pots on a patio table.
Key Takeaway: Choose wax begonias for sunnier borders and "Non-Stop" tuberous begonias for large, rose-like flowers in shaded containers.
Designing Your Garden with Low Growing Varieties
Because of their modest height, these plants are best used in places where they can be appreciated up close. You don't want to hide them behind taller perennials where their intricate flowers and foliage might be missed.
Edging and Borders
One of the most classic uses for low growing begonias is as an edging plant. Planting a single row of wax begonias along the edge of a lawn or a stone path creates a clean, professional look. The consistent height ensures that the border remains neat all season. If you want a more informal look, try staggering two different colors in a zigzag pattern.
The "Filler" in Containers
In container design, we often talk about "thrillers, fillers, and spillers." Low growing begonias are the ultimate fillers. They have a mounding habit that fills the space between a tall central plant (the thriller) and trailing vines (the spillers). Their dense foliage hides the soil and creates a lush, finished appearance. For more ideas, see this guide to begonias in pots and containers.
Window Boxes and Hanging Baskets
For window boxes, you want plants that provide color without blocking the view from the window. Compact begonias are perfect here. They stay below the windowsill while providing a constant display of flowers that can be enjoyed from both the inside and the outside of the home. In hanging baskets, compact upright varieties provide a full, rounded look that complements trailing varieties.
Small Indoor Spaces
If you don't have a large yard, you can still enjoy low growing begonias. Many of the foliage varieties thrive in small pots on a windowsill. They are a great way to bring a touch of the garden indoors, especially in rooms that don't get harsh, direct sunlight.
Finding the Right Spot: Sun and Soil
Success with begonias starts with matching the plant to the right environment. While they are famously easy to grow, they do have a few specific preferences regarding light and drainage. This begonia planting guide offers additional advice on placement.
Light Requirements
Most begonias prefer "dappled" or "filtered" light. This is the kind of light you find under a leafy tree or on a porch with a translucent roof.
- Deep Shade: Many varieties will grow here, but they may produce fewer flowers and the stems can become "leggy" as they reach for light.
- Partial Shade: This is the "sweet spot." Four to six hours of morning sun followed by afternoon shade is ideal.
- Full Sun: Only certain wax begonias with bronze foliage should be placed in full sun. Even then, they need extra water to prevent the leaves from scorching.
Understanding Drainage
Drainage is simply a measure of how fast water leaves the soil. Begonias have thick, succulent-like stems that store water. This means they are sensitive to "wet feet." If the soil stays soggy for too long, the roots and the base of the stems can rot.
To ensure good drainage:
- In Containers: Always use a pot with at least one drainage hole. Use a high-quality potting mix rather than garden soil, as potting mix is designed to stay airy and light.
- In the Ground: If your soil is heavy clay, it will hold water like a bowl. You can improve this by mixing in organic matter like compost or peat moss, which helps create spaces for air and water to move through the soil.
What to do next:
- Identify the shaded spots in your yard that need more color.
- Check the soil drainage by pouring a bucket of water on the area; it should disappear within a few minutes.
- Select a mix of flowering and foliage varieties for maximum visual interest.
How to Plant Begonias
Whether you are starting with tubers or nursery-grown plants, the planting process is straightforward. Timing is the most important factor to remember. Begonias are tropical plants and have no tolerance for frost. See this guide for when to plant begonias outside.
Planting Tubers
If you are planting tuberous begonias, we recommend starting them indoors about 6 to 8 weeks before the last frost date in your area. This gives them a head start so they can begin blooming earlier in the summer.
- Placement: Look at the tuber. One side will be slightly hollow or concave, like a small bowl. This side should face up.
- Depth: Place the tuber on the surface of moist potting soil and cover it with only about half an inch to an inch of soil.
- Watering: Water sparingly at first. Once you see green sprouts appearing, you can begin to water more regularly.
Moving to the Garden
Wait until the soil has warmed up and the nights are consistently above 50°F before moving your begonias outside.
- Spacing: Space low growing begonias about 6 to 9 inches apart. This might look a bit sparse at first, but they will quickly grow to fill the gaps and create a solid carpet of color.
- Planting Depth: When transplanting from a pot to the ground, set the plant at the same depth it was growing in its original container. Burying the stem too deep can lead to rot.
Simple Care for Consistent Blooms
Once your begonias are settled, they require very little daily maintenance. Following a few basic rules for watering and feeding will keep them looking their best until autumn. This begonia care guide covers additional growing details.
Watering Correctly
The goal with begonias is to keep the soil moist but not saturated. A good rule of thumb is to stick your finger into the soil. If the top inch feels dry, it is time to water.
- Water at the base: Try to avoid getting water on the leaves, especially in the evening. Wet leaves can encourage mildew or spotting.
- Container care: Plants in pots dry out much faster than those in the ground. During the hottest weeks of summer, you may need to check your containers daily.
Feeding Your Plants
Begonias are "heavy feeders," meaning they use a lot of nutrients to produce those constant flowers.
- Slow-release fertilizer: You can mix a granular, slow-release fertilizer into the soil at planting time.
- Liquid fertilizer: Alternatively, use a balanced liquid fertilizer every two to four weeks during the growing season. Follow the instructions on the label to avoid over-fertilizing, which can cause more leaf growth but fewer flowers.
Deadheading and Tidying
"Deadheading" is the process of removing spent flowers. Many modern low growing begonias are "self-cleaning," meaning the old flowers fall off on their own. However, if you notice old, brown flowers sticking to the plant, pinching them off will keep the plant looking tidy and may encourage more blooms to form. If a plant becomes too tall or "stretched out," don't be afraid to snip off the top inch of the stems to encourage a bushier shape.
Seasonal Timing and USDA Zones
Begonias are perennials in tropical climates (USDA zones 10 and 11), but in most of the United States, we grow them as annuals. Because we ship our bulbs and plants at the appropriate time for your specific region, you can trust that they will arrive when it is safe to start your gardening project.
If you live in a colder zone and want to save your tuberous begonias for next year, you can lift the tubers in the fall. After the first light frost kills the foliage, carefully dig up the tubers, let them dry in a cool, dark place for a few days, and then store them in a box of peat moss or sawdust in a frost-free area like a basement. In the spring, you can start the process all over again.
Creating a More Beautiful Garden
Gardening should be a rewarding experience that adds beauty to your daily life without adding stress. Low growing begonias are one of the most reliable ways to achieve that goal. They offer a predictable, compact habit and a color range that fits any design style. Whether you are a beginner or have years of experience, these plants provide a simple win for the shaded parts of your yard.

FAQ
Do low growing begonias need full shade?
While they are famous for loving shade, most low growing begonias actually prefer "dappled" or "partial" shade. This means they like a few hours of soft morning sun but need protection from the intense heat of the afternoon. Wax begonias with dark or bronze leaves are the most tolerant of sunnier spots. For more detail, read Do Begonias Grow in Full Shade?
How far apart should I space my begonias?
For a full, lush look that fills in quickly, space your low growing begonias about 6 to 9 inches apart. If you are planting them in a container, you can place them slightly closer, about 4 to 6 inches apart, to get an instantly full appearance. See this guide to begonia spacing for additional guidance.
Why are the leaves on my begonias turning brown at the edges?
Brown edges on the leaves are usually a sign of either "leaf scorch" from too much direct sun or inconsistent watering. If the plant is in a very sunny spot, try moving it to a more shaded area. If the sun isn't the issue, check your soil moisture more frequently to ensure it isn't drying out completely between waterings. This guide to begonias in full sun explains more about sun stress.
Are begonias safe for pets?
Begonias can be toxic to cats and dogs if ingested, particularly the underground tubers. It is always a good idea to place your begonias in areas where pets are unlikely to chew on them, such as in hanging baskets, window boxes, or elevated patio containers.
