Introduction
Finding a splash of color for the shadiest corners of your yard is one of the most rewarding parts of spring planning. While many flowering plants crave the heat of the midday sun, begonias are the celebrated champions of the shade. These versatile plants offer everything from rose-like blossoms to dramatic, metallic-patterned foliage, making them a favorite for gardeners who want high-impact results with straightforward care.
At Longfield Gardens, we enjoy helping you transform every inch of your outdoor space into a beautiful retreat. Whether you have a north-facing porch that rarely sees the sun or a garden bed tucked under a leafy canopy, there is a begonia perfectly suited for that spot.
In this guide, we will explore how to identify the best locations in your yard and home for these tropical beauties. For a broader look at begonia types and care, see our All About Begonias. We will cover light requirements, soil needs, and how to choose the right spot based on the specific type of begonia you are growing. By the end of this article, you will know exactly where to place your plants to ensure they thrive from the first summer bloom until the arrival of autumn frost.
Understanding Light: The Secret to Begonia Success
The most common question gardeners ask is whether begonias need sun or shade. The answer is usually a bit of both, but the balance depends on your specific variety. In their native tropical habitats, most begonias live on the forest floor where they receive "dappled" or "filtered" light. For a deeper look at light needs, see shade plants. This means they are protected from the harsh, direct rays of the sun by the leaves of taller trees.
When you are looking for a place to plant begonias, think about the intensity of the light throughout the day. Morning sun is generally cooler and less stressful for plants. Afternoon sun, especially in the heat of July and August, can be quite intense. Most begonias prefer a spot that stays shaded during those peak afternoon hours to prevent their leaves from scorching or turning brown at the edges.
If you have a spot that gets about four hours of morning sun followed by shade for the rest of the day, you have found a prime location. For areas with deeper shade, such as under a covered patio or beneath dense evergreens, begonias will still grow, but they may produce fewer flowers. If you notice your plants are stretching toward the light and becoming "leggy," it is a sign they might need a slightly brighter location.
Sun-Tolerant Exceptions
While most begonias love the shade, some modern varieties are bred to handle more sun. Wax begonias, which are commonly used for bedding, are a great example. If you choose a wax begonia with bronze-colored foliage, you will find it is much more tolerant of direct sunlight than the green-leaved varieties. The dark pigment in the leaves acts like a natural sunscreen, protecting the plant from heat and light.
Even sun-tolerant begonias usually appreciate a break from the heat in the afternoon. If you live in a very hot southern climate, even the toughest wax begonias will perform better with some afternoon relief. In northern climates, where the sun is less intense, these varieties can often thrive in full sun all day as long as they receive consistent water.
Deep Shade Locations
For the darkest corners of your garden, focus on begonias grown primarily for their leaves, such as Rex begonias. These plants do not rely on heavy flowering for their beauty, so they can handle lower light levels than the big-blooming tuberous types. However, "low light" does not mean "no light." Every plant needs some light to create energy. A spot under a north-facing eave or deep in the shadow of a fence is usually fine, provided the area is not completely dark during the day.
Key Takeaway: Match your begonia to the light you have. Use dark-leaved wax begonias for sunnier spots and save the Rex or tuberous varieties for areas with filtered light or afternoon shade.
Choosing the Right Soil and Drainage
Once you have identified a spot with the right light, the next factor to consider is the soil. Begonias have relatively shallow, delicate root systems. They do not like to sit in "wet feet," which is what gardeners call soil that stays soggy or waterlogged for a long time.
Drainage is simply how fast water leaves the soil after a rain or watering. If you have heavy clay soil, water often stays trapped in the ground, which can lead to root rot. To check the drainage in a potential planting spot, watch the area after a heavy rain. If puddles remain for more than four or five hours, the drainage is likely too slow for begonias.
Improving Your Garden Beds
If your heart is set on a specific spot that has heavy soil, do not worry—you can easily improve it. We recommend mixing in organic matter like compost, finely ground bark, or well-rotted manure. This helps create air pockets in the soil, allowing water to move through more freely while still holding onto the moisture the plant needs to stay hydrated.
Begonias also prefer soil that is slightly acidic, with a pH between 5.5 and 6.5. Most standard garden soils fall into this range, but adding compost is a natural way to keep the soil healthy and slightly acidic over time.
The Benefits of Raised Beds
If your native soil is particularly difficult to work with, consider planting your begonias in a raised bed. Because raised beds sit above the natural ground level, they offer excellent drainage. You can fill them with a high-quality mix of topsoil and compost, giving your begonias the perfect environment from day one. This is also a great way to bring your flowers closer to eye level, where you can appreciate the intricate details of the blooms.
What to Do Next: Soil Prep
- Observe your garden after a rain to identify soggy spots.
- Dig in 2-3 inches of compost to loosen heavy soil.
- Clear away large rocks or debris from the planting area.
- Test the soil with your hand; it should feel crumbly and light, not like sticky clay.
Planting in Containers vs. Garden Beds
Begonias are incredibly versatile, and deciding whether to put them in the ground or a container often depends on how you want to use them in your landscape. Both options work beautifully, but they offer different advantages.
The Case for Containers
Containers are often the best place to plant begonias if you want to decorate specific areas like porches, patios, or balconies. Because you can control the soil exactly, containers eliminate the guesswork of drainage and pH. A high-quality, all-purpose potting mix provides the light, airy structure that begonia roots love.
Containers also allow you to move your plants as the seasons change. If a spot becomes too hot in July, you can simply slide the pot into a shadier area. Hanging baskets are a classic choice for Non Stop begonias and other trailing tuberous begonias. The cascading flowers look stunning when suspended from a porch ceiling or a shepherd's hook in a shaded garden bed.
Using Begonias in the Landscape
Planting begonias directly in the garden is a fantastic way to create a carpet of color. Wax begonias are especially popular for this because they grow in neat, mounded shapes. You can use them to edge a walkway, create a colorful border around a shade tree, or fill in the gaps between larger perennials like hostas and ferns.
When planting in the ground, remember that begonias are tropical plants. They will not survive a frost. In most parts of the country, they are grown as annuals, meaning they are planted fresh each spring. If you live in a warm climate (Zones 9-11), they may live year-round, but for most of us, they provide a spectacular single-season show.
Key Takeaway: Containers offer the most control over soil and light, making them perfect for beginners. Garden beds are ideal for creating large drifts of color and edging pathways.
Where to Plant Based on Begonia Type
Not all begonias are the same. To get the best results, it helps to match the specific type of begonia to the right environment. There are four main categories you will likely encounter.
Tuberous Begonias
These are the stars of the show when it comes to flowers. Tuberous begonias grow from a thick, potato-like tuber and produce large, dramatic blooms that look like roses or camellias. Because the stems and flowers are heavy and somewhat brittle, they need a very specific location.
The best place for tuberous begonias is a spot protected from strong winds. A sheltered porch or a nook near the house is ideal. Because they are prone to breaking in heavy rain, many gardeners prefer to grow them in containers under a roof or awning. They thrive in partial shade and are excellent for adding elegance to a shaded dining area. At Longfield Gardens, we offer a wide variety of these spring-planted bulbs, which can be started indoors for a head start on the season.
Wax Begonias (Fibrous Begonias)
If you are looking for a "set it and forget it" plant for a garden bed, wax begonias are the answer. They are called "wax" begonias because of their shiny, succulent-like leaves. They are very hardy for an annual and can handle a wider range of conditions than other types.
You can plant wax begonias in garden borders, mass plantings, or even window boxes. They are self-cleaning, which means the old flowers fall off on their own, so they always look tidy. They are the best choice for areas that might get a bit more sun, as they are the most heat-tolerant of the group.
Rex Begonias
Rex begonias are grown for their foliage rather than their flowers. Their leaves feature swirls of silver, burgundy, pink, and green. Because their beauty is in the leaves, they are very sensitive to direct sun, which can bleach the colors or burn the foliage.
The best place for a Rex begonia is a cool, shady spot with high humidity. They make excellent houseplants, but they also look wonderful in "mixed" containers on a shady patio. Try pairing them with simple green ferns to let the colorful Rex leaves really stand out.
Cane Begonias (Angel Wing)
Cane begonias have long, upright stems that look a bit like bamboo. The most famous variety is the "Angel Wing" begonia, named for its long, pointed leaves that often have silver spots. These can grow quite tall, sometimes reaching several feet if they are happy.
Since they grow upright, they need a spot with a bit more vertical space. They are often grown in large pots that can be brought inside during the winter. They like bright, indirect light—think of a spot near a window indoors or a bright, covered porch outdoors.
Managing Temperature and Airflow
Because begonias are native to tropical regions, they are very sensitive to temperature. This affects not just where you plant them, but when you put them outside.
The 60-Degree Rule
We recommend waiting to plant begonias outdoors until the nighttime temperatures are consistently above 60°F. If the soil is too cold, the plants will sit still and may even begin to rot. A common mistake is planting them too early in the spring when the air is warm but the ground is still chilly. Patience is a virtue here; waiting for truly warm weather will result in much faster growth once they are in the ground.
The Importance of Airflow
While begonias like a sheltered spot to protect their stems, they also need good air circulation. If you plant them too closely together or in a corner with no breeze, they can develop powdery mildew, which looks like a dusting of white flour on the leaves.
When choosing a spot, ensure there is a little bit of space between your begonias and other plants or walls. If you are planting in the garden, check the spacing recommendations for your specific variety—usually 8 to 12 inches apart. This allows air to move freely around the foliage, keeping the leaves dry and healthy.
What to Do Next: Site Evaluation
- Check the nighttime forecast before moving plants outside.
- Ensure your chosen spot isn't a "dead air" zone with no breeze.
- If planting near a wall, leave a few inches of clearance for airflow.
- Avoid low spots in the yard where cold air might settle on chilly nights.
Designing with Begonias: Creative Ideas
Where you plant begonias can also be a matter of style. Their diverse colors and shapes make them excellent design tools for the home gardener.
Brightening Tree Canopies
One of the most challenging places to grow flowers is under a large shade tree. The roots of the tree often soak up all the moisture, and the shade is too deep for most annuals. However, begonias are a perfect solution. By planting them in the "drip line" (the area under the outer edge of the tree's branches), you can bring color to an otherwise plain area. Just be sure to add some extra compost and water more frequently, as they will be competing with the tree roots for resources.
Enhancing Curb Appeal with Window Boxes
Begonias are a classic choice for window boxes on the north or east side of a house. Their mounded habit fills the box beautifully, and trailing varieties can spill over the edges for a lush, full look. Since window boxes are at eye level, they are a great place to plant varieties with intricate patterns or double blooms.
Creating a Shady Sanctuary
If you have a corner of the yard that feels dark or uninviting, a mass planting of white or light-colored begonias can act like a spotlight. White flowers reflect what little light is available, making the whole area feel brighter and more open. Pair white tuberous begonias with silver-leaved plants for a sophisticated, "moon garden" effect that looks beautiful even at dusk. For more color inspiration, browse our Shop by Color.
Key Takeaway: Use the bright colors of begonias to lead the eye into shaded areas. Light colors like white, yellow, and pale pink are best for brightening up dark corners.
Watering Considerations Based on Location
Where you plant your begonias will also change how you water them. Because they have succulent stems that store water, they are actually quite resilient, but they do have specific preferences.
Container Watering
Plants in containers and hanging baskets dry out much faster than those in the ground. If you place your begonias in a spot that gets a breeze or a few hours of morning sun, you may need to water them every day during the heat of summer. For more watering basics, see our How to Water Your Plants guide. Always check the soil first; if the top inch feels dry, it is time to water.
Ground Watering
Begonias planted in the landscape usually need less frequent watering because the ground stays cool and retains moisture longer. However, if you plant them under a large eave or a thick tree canopy, they might not get much water even when it rains. We suggest checking these "hidden" spots regularly to make sure the soil hasn't become bone-dry.
Water at the Base
Regardless of where you plant them, try to water at the base of the plant rather than over the leaves. Keeping the foliage dry helps prevent fungal issues and keeps the flowers looking their best. A simple watering can with a long spout or a soaker hose is the perfect tool for this job.
Protecting Begonias from the Elements
While we want our begonias to be part of the landscape, sometimes the landscape can be a bit rough on them. Choosing a protected spot is key to keeping them beautiful all season.
Wind Protection
Tuberous begonias, in particular, have very watery, succulent stems. While this makes them beautiful, it also makes them heavy. A sudden gust of wind can easily snap a stem loaded with blossoms. If your yard tends to be windy, plant your begonias against a fence, near a hedge, or in a heavy pot that won't tip over.
Heavy Rain
If you live in an area prone to summer thunderstorms, consider placing your most prized begonias under a porch roof or in a location where they aren't directly under a gutter or "waterfall" from the roof. A heavy downpour can batter the delicate petals and turn a beautiful display into a muddy mess.
Animal Deterrents
Begonias are generally not the first choice for deer or rabbits, but if food is scarce, they might take a nibble. If deer are a concern in your garden, see our How to Protect Your Garden From Deer guide. If you have a lot of wildlife, planting begonias in containers on a raised deck or porch is often enough to keep them out of reach. If you plant them in the ground, placing them near the house or in high-traffic areas can help discourage visitors.
Key Takeaway: A "protected" spot isn't just about shade; it's also about sheltering the plants from wind, heavy rain, and curious animals.
Conclusion
Begonias are truly the jewels of the shade garden. By choosing a location with filtered light, rich soil, and protection from the harshest elements, you set the stage for a spectacular display of color. Whether you are filling a single hanging basket on your porch or planting a grand border along a shaded path, these plants offer a high reward for very little effort.

FAQ
Can begonias grow in full sun?
While most begonias prefer shade, wax begonias with bronze foliage can tolerate full sun, especially in northern climates. However, even sun-tolerant types usually perform better and look healthier if they receive some protection from the intense heat of the afternoon sun.
Do begonias need to be planted in pots or in the ground?
Begonias thrive in both, but your choice depends on the variety. Tuberous begonias are often better in pots where their drainage and light can be strictly controlled, while wax begonias make excellent bedding plants for borders and garden landscapes. If you are starting tubers, our How to Start Tuberous Begonias Indoors guide walks through the process.
How much space should I leave between begonia plants?
For most bedding begonias, like wax varieties, space them about 6 to 8 inches apart. Larger tuberous or cane varieties should be spaced 10 to 12 inches apart to allow for proper airflow, which helps prevent diseases like powdery mildew.
Is it okay to plant begonias under a large tree?
Yes, begonias are excellent for planting under trees because they handle shade well. However, you must ensure they get enough water and nutrients, as the tree roots will compete for moisture. Adding a layer of compost at planting time can help give them a boost.
