Introduction
There is a special kind of excitement that comes with finding the perfect plant to brighten a shaded porch or a quiet corner of the garden. Begonias are often the first choice for these spaces because they offer an incredible variety of jewel-toned flowers and intricate, colorful foliage that looks beautiful from spring through the first frost. Whether you are captivated by the rose-like blooms of tuberous varieties or the waxy shimmer of bedding begonias, these plants bring a dependable cheerfulness to any landscape.
At Longfield Gardens, we want to help you get the most out of every plant you bring home. One of the most frequent questions we hear from home gardeners is whether begonias are perennials that will return every year or annuals that need to be replaced. The answer is a bit more interesting than a simple yes or no, as it depends largely on your local climate and the specific type of begonia you are growing.
In this guide, we will clarify the perennial status of begonias and explain how you can keep these stunning plants part of your garden for many seasons to come. We will cover the differences between the major types, which ones are the easiest to save, and the simple steps you can take to protect them when the weather turns cold. Understanding how begonias grow is the first step toward creating a lush, professional-looking garden that thrives year after year.
Defining the Begonia: Perennial or Annual?
To understand if a begonia is a perennial, we first have to look at how plants are classified. In their native tropical and subtropical habitats in Central and South America, Africa, and Asia, begonias are true perennials. They grow, bloom, and live for many years in these warm, frost-free environments.
However, for most gardeners in the United States, begonias are treated as "tender perennials." This term means that while the plant is biologically capable of living for many years, it cannot survive freezing temperatures. If you live in a region that experiences frost or snow, your begonias will die back in the winter unless you take steps to protect them. This is why many people refer to them as annuals; in a typical northern garden, they complete their outdoor life cycle in a single season.
If you live in USDA hardiness zones 9, 10, or 11, you may find that your begonias stay green and continue to grow all year round. For the rest of us, enjoying them as perennials requires a little bit of help from a sunny windowsill or a cool, dry basement. By understanding this distinction, you can decide whether you want to treat your begonias as temporary summer guests or long-term members of your plant family.
Major Types of Begonias and Their Life Cycles
Not all begonias are the same, and identifying which type you have is the best way to determine how to care for it. Different varieties have different root structures, which dictates how they handle the changing seasons.
Tuberous Begonias
Tuberous begonias are famous for their spectacular, oversized flowers that look like roses, camellias, or carnations. These plants grow from a thick, potato-like underground structure called a tuber. Because the tuber stores energy for the plant, these are among the easiest begonias to keep from year to year. When the weather cools, the plant naturally enters a dormant phase, allowing you to store the tuber in a dry place and replant it the following spring.
Wax Begonias (Fibrous)
Also known as bedding begonias, these are the compact plants often used in mass plantings or as edges for garden borders. They have succulent stems and waxy leaves that may be green or bronze. Wax begonias have fibrous root systems rather than tubers. While they are very hardy during the summer, they do not go dormant in the same way tuberous types do. To keep these as perennials, they must be brought indoors and kept as active houseplants during the winter.
Rex Begonias
Rex begonias are grown primarily for their stunning foliage. Their leaves feature swirls of silver, purple, pink, and deep green, often with unique textures. Like wax begonias, these are fibrous-rooted (or sometimes rhizomatous) and do not tolerate frost. They are very popular as indoor plants and can easily transition from a shady patio in the summer to a bright room inside your home for the winter.
Rhizomatous and Cane-Like Begonias
Rhizomatous begonias grow from thickened stems that creep along the soil surface. Cane-like begonias, such as the popular "Angel Wing" varieties, grow tall, upright stems that resemble bamboo. Both of these types are perennials that are commonly kept as houseplants year-round, though they love spending the summer months outdoors in a protected, shady spot.
Key Takeaway: Most begonias are biologically perennials but are "tender," meaning they will die if exposed to frost. Tuberous varieties are the easiest to save for next year because they can be stored as dormant bulbs.
The Exception: Hardy Begonias (Begonia grandis)
While most begonias require warmth to survive, there is one notable exception that northern gardeners will love: Begonia grandis, commonly known as the hardy begonia. This is one of the few species that can truly be called a perennial in cooler climates, as it is generally hardy down to USDA zone 6.
Hardy begonias look quite different from the flashy tuberous types. They feature elegant, heart-shaped green leaves with red veining on the undersides. In late summer and early autumn, they produce clusters of delicate pink or white flowers. This plant is a wonderful choice for woodland gardens or shaded borders where it can naturalize and spread gently over time.
One thing to keep in mind with hardy begonias is that they are very late to emerge in the spring. You might think the plant didn't survive the winter, only to see it finally pop out of the ground in late May or even June. Once it starts growing, it is a vigorous and reliable performer. It also produces tiny "bulbils" in the leaf axils that drop to the ground, creating new baby plants the following season.
How to Overwinter Your Begonias
If you want to keep your begonias from year to year but don't live in a tropical climate, you have three main options. The best method depends on the type of begonia you are growing and how much space you have indoors. For additional guidance, see How to Overwinter a Begonia Plant.
Method 1: Storing Tuberous Begonias
This is a simple process that works beautifully for varieties like the "Non-Stop" or "Picotee" series.
- Watch the weather: Wait until the first light frost has touched the foliage, or until the leaves begin to yellow in late autumn.
- Lift the tubers: Carefully dig up the plant, taking care not to nick the tuber with your shovel.
- Dry and clean: Cut the stems back to about an inch above the tuber. Lay them out in a warm, dry, protected area for a few days to "cure."
- Pack for winter: Once the tubers are dry and the remaining stem bit falls off easily, brush off any loose soil. Place them in a box filled with dry peat moss, sawdust, or shredded paper.
- Store: Keep the box in a cool, dark, and dry place (like a basement or crawlspace) where temperatures stay between 40°F and 50°F.
- Check periodically: Every month or so, check to make sure the tubers aren't shriveling or showing signs of rot.
Method 2: Bringing Pots Indoors
If your begonias are growing in containers, the easiest way to save them is simply to move the entire pot inside before the first frost. This works well for wax begonias, Rex begonias, and cane-like varieties.
- Acclimate the plant: Move the pot to a porch or a more heavily shaded area for a few days before bringing it into the house. This helps the plant adjust to lower light levels.
- Check for guests: Give the plant a gentle rinse with water to remove any lingering insects.
- Find a bright spot: Indoors, begonias prefer bright, indirect light. An east or west-facing window is usually ideal.
- Adjust your care: Plants grow more slowly indoors. Reduce your watering and stop fertilizing until you see new growth in the spring.
Method 3: Taking Cuttings
If you have a large wax begonia in the garden that you don't have room for indoors, you can take a small cutting to start a new "perennial" plant. Simply snip a 3-to-4-inch piece of a healthy stem, remove the lower leaves, and place it in a glass of water or a small pot of moist potting soil. Begonias root very easily, and by springtime, you will have a healthy young plant ready to go back into the garden.
What to do next:
- Identify whether your begonia has a tuber or a fibrous root system.
- Mark your calendar for the average first frost date in your area.
- Prepare a storage box with peat moss if you plan to save tubers.
- Clear a space on a bright windowsill for any pots you want to bring inside.
Choosing the Right Place for Success
Regardless of whether you treat your begonias as annuals or perennials, they will perform their best when their basic needs are met. Following the "right plant, right place" rule is the easiest way to ensure a full season of color. Longfield Gardens' begonia planting and care guide offers additional growing advice.
Light Requirements
Most begonias are famous for their ability to thrive in the shade, but "shade" can mean different things. Most varieties prefer dappled sunlight or "bright shade." This is the kind of light you find under a tall tree or on a covered porch.
- Wax begonias can often handle more sun than other types, especially if they have bronze leaves.
- Tuberous begonias have delicate stems and flowers that can scorch in the hot afternoon sun. They prefer a spot that is bright but protected from direct rays.
- Rex begonias need high-quality light to maintain their vibrant leaf colors but should never be in direct midday sun.
Soil and Drainage
If there is one thing begonias do not like, it is "wet feet." Drainage refers to how fast water leaves the soil. Begonias need soil that stays moist but never stays soggy.
- In the garden, choosing a spot with loose, organic-rich soil is best. If your soil is heavy clay, planting in raised beds or containers can solve drainage issues instantly.
- For containers, always use a high-quality potting mix and ensure the pot has drainage holes at the bottom.
Simple Care for Long-Lasting Blooms
Begonias are relatively low-maintenance, but a few simple habits will keep them looking their best from the day you plant them until the end of the season. For more detailed advice, read How to Care for Begonia Plants.
Water Correctly, Not Constantly
It is better to water deeply and then let the top inch of soil dry out before watering again. When you do water, try to aim for the base of the plant rather than the leaves. Wet foliage can sometimes lead to mildew or spotting, especially in humid climates. If you are growing begonias in hanging baskets, they may need more frequent checks, as baskets dry out faster than the ground.
Feeding Your Plants
Because begonias bloom so prolifically, they appreciate a bit of extra energy. A balanced, water-soluble fertilizer applied once a month during the growing season is usually plenty. If you prefer a "set it and forget it" approach, you can mix a slow-release granular fertilizer into the soil at planting time.
Grooming and Pruning
One of the best things about many modern begonia varieties is that they are "self-cleaning," meaning the old flowers fall off on their own. However, if your plants start to look a little "leggy" (meaning the stems are long and thin with few leaves), don't be afraid to pinch them back. Sniping off the top inch of a stem encourages the plant to branch out, resulting in a fuller, bushier look with more flowers.
Troubleshooting Common Issues
Even the most experienced gardeners run into a few hiccups now and then. If your begonias aren't looking quite right, the fix is usually very simple.
My begonia isn't blooming
The most common cause for a lack of flowers is not enough light. While begonias love shade, they still need "bright" light to produce blooms. If your plant is in a very dark corner, try moving it to a spot that gets a bit more indirect light. Another possibility is too much nitrogen in your fertilizer, which encourages leaves but not flowers. Switching to a balanced fertilizer can help.
The leaves are turning yellow
Yellow leaves usually mean the soil is staying too wet. Check the drainage holes in your container or reduce your watering frequency. Give the soil a chance to dry out slightly so the roots can breathe.
The stems are breaking
Tuberous begonias, in particular, can have very heavy flowers on somewhat brittle stems. If you are growing a variety with large, double blooms, providing a small bamboo stake for support can prevent the stems from snapping during a summer rainstorm.
Growing Begonias in Different Environments
Because begonias are so versatile, you can enjoy them in almost any part of your home or landscape.
- In the Garden Bed: Wax begonias make excellent "filler" plants. Because they stay compact, they create a beautiful carpet of color. Try planting them in groups of three or five for the best visual impact.
- In Hanging Baskets: Trailing tuberous begonias are the stars of the hanging basket world. They will cascade over the sides of the pot, creating a waterfall of blossoms. Our "Hanging Basket Mixed" varieties are specifically selected for this beautiful growth habit.
- In Window Boxes: Combine upright begonias with trailing plants like ivy or sweet potato vine. The begonias provide the height and color, while the other plants soften the edges of the window box.
- As Houseplants: Many gardeners find that Rex begonias are so beautiful they never want to put them outside. They make wonderful indoor companions, adding a pop of color to a desk or bookshelf.
Realistic Expectations for Your Garden
Gardening is a partnership with nature, and results can vary depending on your specific environment. While we provide high-quality tubers and plants at Longfield Gardens, factors like an unusually cold spring, a very humid summer, or the specific mineral content of your soil can all influence how your begonias perform.
It is also helpful to remember that begonias are slow starters. Tuberous begonias, in particular, take their time to wake up in the spring. If you plant your tubers and don't see green shoots for a few weeks, don't worry—they are likely just busy establishing roots below the surface. The wait is always worth it when those first spectacular blooms finally appear.
Conclusion
Whether you choose to treat begonias as long-blooming annuals or put in the little bit of extra effort to keep them as perennials, they are among the most rewarding plants you can grow. Their ability to bring vivid color to the shadiest parts of the yard makes them an essential tool for any home gardener. By matching the right variety to your space and following the simple steps for watering and winter care, you can enjoy a more beautiful and vibrant garden every year.
- Identify your begonia type to know if it can be stored as a tuber or kept as a houseplant.
- Provide bright, indirect light and well-drained soil for the best growth.
- Water deeply but allow the soil to dry slightly between sessions.
- Bring tender varieties indoors before the first frost hits your area.

FAQ
Can begonias survive the winter outside?
In most parts of the United States (USDA zones 3–8), begonias cannot survive the winter outside because they are sensitive to frost. Only the "hardy begonia" (Begonia grandis) is capable of surviving outdoors in cooler zones, typically down to zone 6. All other types must be brought indoors or stored as dormant tubers to survive until spring.
Do I need to dig up my begonias every year?
You only need to dig up your begonias if you live in a climate with freezing winters and want to keep the plants for next year. Tuberous begonias are the easiest to save by digging up the tubers and storing them in a cool, dry place. If you prefer a lower-maintenance approach, you can simply treat them as annuals and plant fresh ones each spring.
How do I know if my begonia is tuberous or fibrous?
The easiest way to tell is by looking at the roots or the growth habit. Tuberous begonias usually have very large, showy flowers and grow from a brown, woody-looking bulb (tuber) at the soil line. Fibrous or wax begonias have smaller, cluster-like flowers, waxy leaves, and a mass of thin, hair-like roots instead of a solid tuber.
Can I grow begonias in full sun?
Most begonias prefer shade or partial shade, as their leaves and flowers can easily scorch in intense sunlight. However, some wax begonias—especially those with bronze-colored leaves—are more tolerant of the sun. If you live in a northern climate with milder sun, they may handle more light than they would in the hot, southern United States. For more detail, see Where to Plant Begonia Bulbs.
