Introduction
There is a unique sense of wonder that comes from watching a new begonia leaf unfurl. These plants are famous for their stunning variety, offering everything from metallic silver swirls and deep velvet purples to vibrant, polka-dotted greens. Whether you are looking for a pop of color for your bookshelf or a dramatic statement piece for your dining room table, begonias are a fantastic choice for home gardeners of all experience levels.
At Longfield Gardens, we enjoy helping people bring the beauty of the natural world into their homes with our Begonia Flower Bulbs for Sale collection. Begonias are particularly rewarding because they offer an incredible range of textures and colors that few other plant groups can match. Many people first encounter these plants in outdoor shade gardens, but they are equally at home—and often even more spectacular—when grown as indoor specimens.
This guide will help you understand which begonias thrive inside, how to provide the light and water they love, and how to keep them looking vibrant through every season. Whether you are a beginner or looking to expand your collection, you will find that begonias are among the most versatile and enjoyable plants you can grow. With a few simple steps, you can turn any bright corner of your home into a lush, tropical retreat. For a broader overview of begonia types and care, see our All About Begonias guide.
The Short Answer: Are Begonias Indoor Plants?
The short answer is a resounding yes. While many people plant begonias in their flower beds or hanging baskets for the summer, most begonias are actually tropical perennials. Because they are native to warm, humid regions like Central and South America, Asia, and Africa, they cannot survive a frost. This makes them perfectly suited for life indoors, where temperatures remain stable and comfortable year-round.
When we think about growing begonias inside, we usually group them by their root systems and growth habits. Each type has a slightly different personality, but they all share a love for bright light and consistent care. Some types, like the Rex begonia, are grown almost entirely for their psychedelic foliage. Others, like the Angel Wing or wax begonia, provide a steady stream of delicate flowers that can brighten up a winter day.
Growing begonias indoors allows you to appreciate the fine details of their leaves that might be missed in a large garden bed. From the tiny hairs that give some leaves a fuzzy texture to the shimmering, iridescent sheen of others, these plants are meant to be seen up close. By bringing them inside, you create a controlled environment where they can truly shine.
Understanding the Different Types of Indoor Begonias
To have the best success, it helps to know which type of begonia you are growing. While there are thousands of species and hybrids, most houseplant enthusiasts focus on a few main categories. Matching your care to the specific type of begonia you have is one of the simplest ways to ensure a healthy plant.
Rhizomatous Begonias and Rex Begonias
Rhizomatous begonias are the most common choice for indoor gardeners. These plants grow from a thick, fleshy stem called a rhizome that creeps along the surface of the soil. The rhizome acts as a storage tank for water and nutrients, which makes these plants a bit more resilient if you occasionally forget to water them.
The most famous members of this group are the Rex begonias. These are often called "painted-leaf begonias" because their foliage looks like a work of art. You might see varieties with silver, burgundy, pink, and forest green all on a single leaf. They generally stay under 12 to 18 inches tall, making them ideal for tabletops and plant stands.
Cane-Like Begonias (Angel Wings)
Cane begonias are named for their long, upright stems that resemble bamboo. These are often called "Angel Wing" begonias because their long, pointed leaves are shaped like wings. Many of these varieties feature silver spots or metallic splashes on dark green or bronze leaves.
Cane begonias are excellent indoor plants because they are very sturdy. They can grow quite tall—sometimes several feet—if given a support stake. They are also prolific bloomers, producing clusters of drooping pink, white, or red flowers throughout the year if they get enough light.
Fibrous-Rooted and Wax Begonias
Wax begonias are the classic bedding plants you see in parks and garden borders. They have succulent, glossy leaves and rounded flowers. While they are often treated as annuals outdoors, they make charming, low-maintenance houseplants. They are generally smaller and more compact than cane begonias, fitting perfectly on a sunny windowsill.
Tuberous Begonias
Tuberous begonias, like the Non Stop Begonias or pendula varieties we often carry, are famous for their massive, rose-like blooms. These are slightly different from other indoor types because they typically require a period of dormancy. While they can be grown indoors during their blooming season, they will eventually want to "sleep" for the winter. We will cover how to handle that transition later in this guide.
Key Takeaway: Most begonias are tropical and thrive indoors. Rhizomatous and Rex types are prized for foliage, while Cane and Wax types offer beautiful flowers.
Finding the Best Light for Your Begonias
Getting the light right is the most important step in keeping your indoor begonias happy. In their native habitats, most begonias grow on the forest floor. This means they are adapted to "bright shade"—the kind of light that is strong but filtered through the leaves of taller trees.
The Ideal Window
An east-facing window is often the best spot for an indoor begonia. This location provides gentle morning sun, which isn't too hot, and bright, indirect light for the rest of the day. A north-facing window can also work, though your plant might grow more slowly and produce fewer flowers.
If you have a south- or west-facing window, the light might be a bit too intense during the middle of the day. Direct, hot sunlight can scorch the delicate leaves, causing brown, "crispy" edges or faded colors. To fix this, you can simply pull the plant a few feet back from the glass or use a sheer curtain to soften the light.
Signs Your Plant Needs More Light
If your begonia is "reaching" toward the window and the stems are becoming long and thin (leggy), it likely needs more light. For flowering types like Angel Wings, a lack of blooms is often a sign that the plant needs a bit more brightness to fuel its energy.
Using Artificial Lights
If your home doesn't have many windows, begonias grow very well under standard LED grow lights. This is a great way to keep your foliage looking vibrant during the dark winter months. Position the light about 12 to 18 inches above the plant and keep it on for about 12 hours a day to mimic a tropical day-night cycle.
Watering Your Begonias Correctly
Watering is where many new gardeners feel a bit nervous, but it is easy once you know what the plant is telling you. Begonias have succulent-like stems, which means they store some moisture inside. Because of this, they do not like to sit in soggy soil, which can lead to root issues.
The Knuckle Test
The best way to tell if your begonia needs water is to use your finger. Stick your finger about an inch into the soil. If it feels dry, it is time to water. If it still feels damp, wait a few days and check again. This "deep, then let it dry" method is much better for the plant than giving it small sips of water every day.
How to Water
When you do water, do it thoroughly. Pour water onto the soil until it begins to drain out of the holes at the bottom of the pot. Make sure to empty the saucer afterward so the plant isn't sitting in a puddle. Try to avoid getting too much water on the leaves themselves, as this can lead to spots or mildew. Watering in the morning is ideal, as it allows any stray drops on the foliage to evaporate during the day.
Adjusting for the Seasons
Your begonia will need more water in the summer when it is growing fast and the air is warm. In the winter, when the plant slows down and there is less sunlight, you can cut back on watering. Always trust the feel of the soil rather than a strict calendar schedule.
Managing Humidity for Lush Growth
Since begonias are tropical plants, they enjoy a bit of moisture in the air. Most modern homes have very dry air, especially in the winter when the heat is running. If the humidity is too low, you might notice the edges of your begonia's leaves turning brown or curling.
You do not need a fancy greenhouse to keep your begonias happy. Here are a few simple ways to increase humidity:
- The Pebble Tray: This is a classic gardening trick. Fill a shallow tray with small stones or pebbles and add water until it is just below the tops of the stones. Set your begonia pot on top of the pebbles. As the water evaporates, it creates a small "microclimate" of humid air right around the leaves.
- Grouping Plants: Plants "breathe" out moisture through their leaves. By grouping your begonias together with other houseplants, they can share the humidity they create.
- The Bathroom or Kitchen: These are naturally the most humid rooms in the house. A bright bathroom is often a paradise for a Rex begonia.
While some people suggest misting the leaves with a spray bottle, we generally recommend the pebble tray method instead. Misting only increases humidity for a few minutes and can encourage fungal issues if the leaves stay wet for too long.
What to do next:
- Check the soil with your finger before watering.
- Place your plant in a bright, east-facing window.
- Set up a simple pebble tray if the air feels dry.
- Rotate the pot once a week so the plant grows evenly toward the light.
Choosing the Right Soil and Pot
Begonias have relatively fine, delicate roots that need plenty of air to stay healthy. This means they need soil that drains quickly but stays lightly moist.
The Best Soil Mix
A standard high-quality potting mix works well, but you can make it even better by adding a handful of perlite or orchid bark. This helps create "air pockets" in the soil, which prevents it from becoming a heavy, muddy mess. Avoid using "garden soil" or "topsoil" from the yard, as these are too heavy and may contain pests or diseases that can thrive indoors.
Selecting a Pot
Always choose a pot with drainage holes. This is the single best way to prevent overwatering. Terra cotta pots are a popular choice because the clay is porous and helps the soil "breathe." However, because they dry out faster, you may need to water a bit more often. Plastic or glazed ceramic pots hold moisture longer, which can be helpful if you have a busy schedule.
When it is time to move your begonia to a larger home, only go up one size at a time (for example, from a 4-inch pot to a 6-inch pot). Begonias actually like to be a little bit snug in their pots. A pot that is too large holds too much extra soil, which stays wet for too long and can lead to trouble for the roots.
Feeding and Maintenance
To keep your indoor begonias looking their best, they appreciate a little bit of regular maintenance. This isn't a chore; it’s a way to stay connected with your plants and catch any small changes early.
Fertilizing
During the growing season (spring through early autumn), you can feed your begonias with a balanced liquid fertilizer. We recommend using it at half-strength about once a month. This provides the nutrients they need to produce those vibrant leaves and flowers. In the winter, when growth naturally slows down, you can stop fertilizing entirely.
Grooming Your Plant
As your begonia grows, some older leaves will naturally turn yellow and die back. This is a normal part of the plant's life cycle. Simply snip them off at the base with a clean pair of scissors. This keeps the plant looking tidy and allows it to focus its energy on new, healthy growth.
If your cane begonia is getting too tall or "leggy," don't be afraid to give it a haircut. Snipping off the top of a stem (pinching) encourages the plant to grow more side branches, which makes it look fuller and bushier.
Pest Prevention
The best way to handle pests like aphids or spider mites is to prevent them. When you bring a new plant home, keep it away from your other plants for a week or two to make sure it is healthy. Every time you water, take a quick peek at the undersides of the leaves. If you see any unwanted visitors, a gentle wipe with a damp cloth or a spray of mild insecticidal soap usually does the trick.
Bringing Outdoor Begonias Inside for Winter
If you have begonias in your garden or on your patio, you don't have to say goodbye when the weather turns cold. Many gardeners at Longfield Gardens successfully bring their outdoor begonias inside to enjoy all winter long. For trailing container options, browse our Hanging Begonias collection.
Timing the Move
The most important rule is to bring them in before the first frost. Begonias are very sensitive to cold. Once the nighttime temperatures start dipping into the 50s (°F), it is time to prepare for the move. If you are unsure about timing for your area, check the Hardiness Zone Map. If you are planning a new order, our Shipping Information page explains scheduling by zone.
The Transition Process
Plants can experience a bit of "shock" when they move from the bright, humid outdoors to the dimmer, drier indoors. To make it easier for them:
- Inspect for Pests: Give the plant a thorough look-over. You might even want to give it a gentle rinse with a hose to wash away any hitchhiking bugs.
- Prune Back: If the plant has grown very large, you can trim it back by about a third. This makes it easier to manage and reduces the stress on the roots.
- Expect Some Leaf Drop: Don't worry if your plant loses a few leaves in the first week or two. It is simply adjusting to the new light levels. It will soon grow new leaves that are better adapted to indoor conditions.
Overwintering Tuberous Begonias
Unlike Rex or Angel Wing begonias, tuberous begonias (like the Begonia Non Stop Mix - Bulk Offer) usually want a rest in the winter. In the autumn, stop watering the plant and let the foliage die back naturally. Once the soil is dry, you can dig up the potato-like tuber, brush off the dirt, and store it in a cool, dry place (like a basement) in some peat moss or vermiculite. In the spring, you can pot it up again and watch it come back to life.
The Magic of Propagation
One of the most enjoyable things about begonias is how easy they are to share. You can grow entirely new plants from just a single leaf or a small stem cutting. This is a fun, low-stress way to expand your indoor garden or grow gifts for friends.
Stem Cuttings
For cane-like begonias, simply snip off a 3- to 4-inch piece of stem that has at least two "nodes" (the bumps where leaves grow). Remove the bottom leaves and place the stem in a glass of water. In a few weeks, you will see white roots beginning to grow. Once the roots are about an inch long, you can plant the cutting in a small pot of soil.
Leaf Cuttings
Rex and rhizomatous begonias can be propagated from a single leaf. You can cut a healthy leaf into small wedges (each with a main vein) and press them into damp potting soil. Keep the pot in a bright spot and cover it with a clear plastic bag to keep the humidity high. Before long, tiny new plantlets will begin to sprout from the edges of the leaf.
A Note on Safety
While begonias are beautiful, it is important to remember that they can be toxic if eaten. They contain calcium oxalates, which can cause irritation in the mouth and throat. If you have curious pets or small children, it is best to keep your begonias on a high shelf or in a hanging basket where they cannot be reached. Always check a trusted source for specific toxicity details regarding your pets.

FAQ
Is begonia an indoor plant or an outdoor plant?
Begonias can be both. While many people use them as summer bedding plants in the garden, they are tropical perennials that cannot survive freezing temperatures. This makes them excellent year-round houseplants, provided they are given enough light and humidity inside.
How much sunlight does an indoor begonia need?
Indoor begonias prefer bright, indirect light. An east-facing window is usually perfect because it offers gentle morning sun. Avoid placing them in direct, harsh afternoon sunlight, which can burn their delicate leaves, but ensure they aren't in a dark corner, or they may become leggy.
Why are the leaves on my indoor begonia turning brown at the edges?
Brown, crispy edges are usually caused by low humidity or underwatering. Since begonias are tropical, they enjoy moisture in the air. Using a pebble tray or grouping plants together can help. It can also happen if the plant is receiving too much direct, hot sunlight.
Are begonias easy to take care of indoors?
Yes, most begonias are quite easy for beginners. The key is to avoid overwatering—let the top inch of soil dry out before watering again—and to provide consistent, bright light. Rhizomatous and Cane begonias are particularly sturdy and forgiving for those new to indoor gardening.
