Introduction
One of the greatest joys of gardening is discovering a plant that feels at home almost anywhere you put it. Begonias are exactly that kind of versatile treasure, offering a spectacular range of flower colors and leaf patterns that can brighten a dim corner of your living room just as easily as a shaded porch. At Longfield Gardens, we have seen how these plants transform spaces with their nonstop blooms and artistic foliage, making them a favorite for both first-time growers and seasoned enthusiasts. If you’re ready to shop, start with our begonia flower bulbs.
The question of whether a begonia is an indoor or outdoor plant actually has a very happy answer: it can be both. Because the begonia family is so diverse, there are specific varieties that thrive in the garden and others that are perfectly suited for life on a windowsill. Knowing which type you have is the secret to helping it flourish. For a broader overview of placement, see our Where to Plant Begonias: Sun or Shade? guide.
This guide will help you identify the best begonias for your specific needs, whether you want to line a garden path or decorate an indoor shelf. We will look at how to care for them in both environments and how to move them between the two as the seasons change. In most cases, the decision to grow begonias indoors or outdoors simply depends on your local climate and the specific variety you choose.
The Versatile World of Begonias
The begonia family is massive, containing over 2,000 different species and even more hybrids. Most of these plants are native to tropical and subtropical regions. This tropical heritage is the reason they are so flexible. In warm, frost-free climates, they can live outdoors all year. In most parts of the United States, we enjoy them as outdoor annuals in the summer and as cherished houseplants in the winter.
To decide where your plant belongs, it helps to understand the three most common groups you will find at a garden center or through our shipping facility. Tuberous begonias are the stars of the summer garden, known for their massive, rose-like blooms. Wax begonias are the reliable workhorses of flower beds. Rex and "angel wing" begonias are the foliage experts, often grown indoors for their stunning leaves. For more inspiration in part-shade planting, browse our Summer Flowers for Shade collection.
Most begonias share a love for "bright shade." This means they want plenty of light but don't want the hot, direct afternoon sun to scorch their leaves. This middle-ground light requirement is exactly why they transition so well between a patio and a bright living room.
Growing Begonias as Outdoor Plants
For many gardeners, begonias are the "go-to" choice for adding color to areas that don't get much sun. While many flowering plants need six to eight hours of direct sunlight to bloom, begonias are happy with much less.
Tuberous Begonias for Shade Gardens
Tuberous begonias are some of the most popular outdoor varieties. They grow from a thickened root called a tuber, which stores energy for the plant. These varieties, such as the "Nonstop" or "Picotee" series, produce large, double flowers that look like roses or camellias. If you love this style, take a look at our Tips for Growing Tuberous Begonias.
When planting tuberous begonias outdoors, wait until the soil is warm and there is no danger of frost. They love hanging baskets, window boxes, and containers. Because they have a mounding or trailing habit, they look beautiful spilling over the edges of a pot. They prefer a spot that gets morning sun and afternoon shade. If they get too much hot sun, the flowers may wilt; if they get too much shade, they will produce fewer blooms.
Wax Begonias for Sunny Spots
If you have a spot that gets a bit more sun, wax begonias (also called fibrous begonias) are an excellent choice. These are small, mounding plants with waxy, succulent-like leaves. They are incredibly tough and can handle more heat and sunlight than tuberous types.
Wax begonias are often used as "bedding plants" to create a carpet of color in garden borders. You can find them with either green or bronze-colored leaves. A simple rule to remember is that bronze-leaf varieties usually handle direct sun better than the green-leaf types. They are very reliable and will keep blooming from late spring right until the first frost. For a quick refresher on the full family, visit our All About Begonias page.
Soil and Water Outdoors
Outdoors, the most important thing for a begonia is drainage. Drainage is simply how fast water moves through the soil. Begonias have fleshy stems that hold a lot of water, which makes them prone to rot if the soil stays too soggy.
Use a high-quality potting mix for containers. If you are planting in the ground, make sure the soil is loose and rich in organic matter. A good technique is the "deep soak and dry" method. Water the plants thoroughly until water runs out the bottom of the pot, then let the top inch of soil dry out before you water again.
Key Takeaway: Outdoor begonias provide constant color in shady or partially sunny areas where other flowers might struggle. Focus on well-draining soil and protected locations for the best results.
What to do next for outdoor success:
- Wait for consistently warm nights (above 50°F) before moving plants outside.
- Choose a location protected from strong winds, as begonia stems can be brittle.
- Check the soil every two days during the heat of summer.
- Apply a balanced, water-soluble fertilizer every two weeks to support continuous blooming.
Growing Begonias as Indoor Plants
While any begonia can spend time indoors, certain varieties are famous for being excellent houseplants. These are usually grown for their spectacular foliage rather than just their flowers. If you want a helpful place to begin, see Are Begonias Good House Plants?.
Rex Begonias: The Foliage Kings
Rex begonias are the most popular indoor choice. They are known as "rhizomatous" begonias, meaning they grow from a thick stem that sits right on the soil surface. Their leaves come in incredible patterns of silver, purple, pink, and deep green.
Indoors, Rex begonias thrive in the stable temperatures of a home. They don't need direct sunlight; in fact, a north-facing or east-facing window is often perfect. They enjoy a bit of humidity, so they are great candidates for a bathroom with a window or a kitchen where there is moisture in the air. For more indoor-growing detail, read How Do You Care for a Begonia Plant Indoors?.
Angel Wing and Cane Begonias
Cane begonias get their name from their long, bamboo-like stems. The "angel wing" variety is a subset of this group, named for its long, pointed leaves that often feature silver spots. These are very easy to grow indoors and can eventually become quite tall, looking like a beautiful indoor shrub.
These begonias do produce clusters of drooping flowers, usually in shades of pink or white. They like a little more light than the Rex types. A spot near a bright window with a sheer curtain to filter the sun is ideal.
Indoor Care Basics
The environment inside a house is drier than the outdoors. To keep an indoor begonia happy, keep the soil consistently moist but never waterlogged. Since there is less wind and sun indoors, the soil will dry out more slowly than it does in a garden pot.
One simple tip for indoor begonias is to avoid getting water on the leaves. Water the soil directly at the base of the plant. This helps prevent spots or mildew on the beautiful foliage. If your home is very dry in the winter, you can place the pot on a tray filled with pebbles and a little water. As the water evaporates, it creates a small zone of humidity around the plant. For a quick overview of general care, our How Do I Care for a Begonia Plant? guide is a useful companion.
Key Takeaway: Indoor begonias are prized for their artistic leaves and ability to thrive in indirect light. They are perfect for adding life to rooms that don't get harsh, direct sun.
What to do next for indoor success:
- Place your plant in a room with bright, filtered light.
- Use a pot with a drainage hole to prevent water from sitting at the roots.
- Rotate the pot every week so the plant grows evenly on all sides.
- Keep the plant away from cold drafts or heating vents.
Moving Begonias Between Indoors and Outdoors
Many gardeners treat begonias as "vacationing" plants. They spend the glorious summer months on the patio and the cold winter months safely inside the house. This is a great way to enjoy your plants year-round.
Summering Indoor Plants Outside
If you have Rex or angel wing begonias that live inside, they will often show a burst of growth if you move them outside for the summer. The key is a gradual transition. This is called "hardening off."
Start by putting your indoor plant in a very shaded, protected spot for just a few hours a day. Over a week or two, you can gradually leave it out longer. Never move an indoor begonia directly into the sun; the leaves will burn almost instantly. A shaded porch or the underside of a large tree is a perfect summer home for indoor begonias.
Bringing Garden Begonias Inside for Winter
Since begonias are tropical, they will not survive a freeze. As autumn approaches and temperatures start to dip toward 50°F at night, it is time to bring them in.
For wax begonias or cane types, you can simply bring the whole pot inside. Check carefully for any hitchhiking insects before you move them. Once inside, the plant may drop a few leaves as it adjusts to the lower light levels. This is normal. Just reduce your watering slightly, as the plant will grow more slowly in the winter. If you’re moving a Rieger type, our Can You Plant Rieger Begonias Outside? article covers the transition well.
Overwintering Tuberous Begonias
Tuberous begonias are a bit different. In the fall, they naturally want to go dormant. As the leaves begin to yellow, stop watering the plant. Once the foliage has died back, you can lift the tubers out of the soil.
Gently brush off the dirt and let the tubers dry in a cool, shaded spot for a few days. Then, store them in a box of peat moss or sawdust in a cool, dark place (like a basement) where they won't freeze. In the spring, about six to eight weeks before the last frost, you can restart them in pots indoors. We find that this cycle of rest and growth keeps the tubers healthy and productive for many years.
Choosing the Best Location Based on Variety
To help you decide where to put your begonia, we can look at the specific needs of the most common types. Finding the "right plant for the right place" is the easiest way to ensure gardening success.
When to Choose the Outdoors
If you want a massive display of flowers or a colorful border in your yard, the outdoors is the place to be.
- Tuberous Begonias: Best for shaded porches, north-facing balconies, and hanging baskets.
- Wax Begonias: Best for garden edges, mass plantings, and spots with "dappled" sunlight (sunlight that filters through tree leaves).
- Hardy Begonia (Begonia grandis): This is a rare exception that can stay outdoors all year in USDA Zones 6 through 9. It is a true perennial that comes back from the roots every spring.
When to Choose the Indoors
If you want to enjoy beautiful patterns and textures up close, or if you don't have a garden space, indoor growing is ideal.
- Rex Begonias: Perfect for desks, side tables, and terrariums.
- Angel Wing/Cane Begonias: Great for floor pots or tall pedestals where their height can be appreciated.
- Rhizomatous Begonias: Good for shallow pots on windowsills.
Practical Tips for Success in Any Environment
Regardless of whether your begonia is an indoor or outdoor plant, a few simple rules will keep it healthy. Begonias are not demanding, but they do appreciate a little consistency.
Temperature Matters
Begonias are most comfortable in the same temperatures that humans enjoy. They like it between 65°F and 75°F during the day. If you are comfortable in a room without a coat, your begonia is likely happy too. Outdoors, they thrive in the warmth of summer but start to struggle when temperatures stay consistently above 90°F or drop below 50°F.
Feeding Your Plants
Begonias are "heavy feeders," meaning they use a lot of nutrients to produce those beautiful leaves and flowers. For plants in containers (both indoors and out), the nutrients in the potting soil are used up fairly quickly.
Use a balanced, water-soluble fertilizer. A "balanced" fertilizer has three equal numbers on the label, like 10-10-10. During the active growing season (spring through fall), fertilize your begonias once or twice a month. If the plant is dormant or growing very slowly in the winter, stop fertilizing until new growth appears in the spring. For more plants you can buy in quantity, browse our Spring Flower Bulk Buys.
Space and Airflow
Begonias have dense foliage, which can sometimes trap moisture. This can lead to powdery mildew, a white dust-like fungus on the leaves. To prevent this, make sure your plants have enough space for air to move around them. Don't crowd too many pots together. If you are growing them indoors, occasionally opening a window or running a small fan can help keep the air fresh.
Key Takeaway: Success with begonias comes down to moderate light, careful watering, and avoiding extreme temperatures. Whether inside or out, these plants reward a little attention with a lot of beauty.
Safety Note for Pet Owners
It is important to note that begonias contain calcium oxalates, which can be toxic to cats and dogs if eaten. The tubers contain the highest concentration of these compounds. If you have curious pets that like to nibble on greenery, it is best to keep your indoor begonias on high shelves or in hanging baskets where they are out of reach. In the garden, most pets tend to ignore them, but it is always good to be aware and monitor your furry friends.
Conclusion
Whether you choose to grow begonias as indoor houseplants or outdoor garden stars, these plants offer a level of beauty and variety that is hard to match. By matching the right variety to your space—using wax and tuberous types for the garden and Rex or cane types for the home—you can enjoy their presence in every season. At Longfield Gardens, we take pride in providing high-quality tubers and plants that help you bring this tropical elegance into your own life.

FAQ
Can I move my begonia from the garden to the house?
Yes, you can bring many begonias inside for the winter. Wax begonias and cane begonias transition well into pots. It is best to do this before the first frost while nighttime temperatures are still around 50°F. Be sure to check for any garden pests before bringing the plant into your home.
Do begonias need a lot of sunlight?
Begonias generally prefer bright, indirect light rather than hot, direct sun. Outdoor varieties like "bright shade" or morning sun with afternoon protection. Indoor varieties thrive near bright windows where the light is filtered. If the leaves look pale or the plant is stretching, it likely needs a bit more light. For a simple deadheading refresher, see How and Why to Deadhead Flowers.
How often should I water my begonias?
Water your begonias when the top inch of soil feels dry to the touch. It is better to water them thoroughly and let the excess drain away than to give them small sips every day. Avoid keeping the soil "soggy," as this can lead to root issues. In the winter, indoor begonias typically need less water than they do in the summer.
Are there any begonias that can stay outside all winter?
Most begonias are tropical and will die in freezing temperatures. However, the Begonia grandis, also known as the hardy begonia, is an exception. It is perennial in USDA Zones 6 through 9. It will die back to the ground in the winter and sprout again from the roots once the soil warms up in the spring.
