Introduction
Walking through a garden filled with begonias is one of the most rewarding experiences a gardener can have. Whether they are spilling over the edges of a hanging basket or lining a shaded walkway with waxy green leaves, these plants offer a level of color and texture that is hard to match. At Longfield Gardens, we see firsthand how begonias transform outdoor spaces into lush, tropical retreats with very little effort.
The question of whether begonias are annuals or perennials is one of the most common things we hear from home gardeners. The answer is quite interesting because it depends largely on where you live and which type of begonia you choose. Understanding this distinction is the key to enjoying these beautiful blooms year after year.
In this guide, we will explore the botanical nature of begonias, how they behave in different American climates, and how you can help them survive the winter. We want to help you get the most out of your garden, whether you treat your begonias as a one-season splash of color or a long-term investment. While begonias are technically perennials by nature, most gardeners in the United States grow them as annuals due to their sensitive, tropical roots.

The Short Answer: Perennial by Nature, Annual by Climate
From a strictly botanical perspective, all begonias are perennials. This means that in their native tropical and subtropical habitats in Africa, Asia, and Central and South America, they grow and bloom continuously for many years. They do not have a biological "reset button" that forces them to die after a single flowering season.
However, for the vast majority of gardeners in the United States, begonias are treated as annuals. This is because they are "frost-tender," which is a gardening term that means the plant cannot survive freezing temperatures. Even a light frost can damage the succulent stems and leaves of a begonia, and a hard freeze will usually kill the root system or tuber entirely. If you want a seasonal choice that blooms in shade, our Begonia Non Stop Mix collection is a good place to browse.
In warmer regions, specifically USDA hardiness zones 9 through 11, begonias can stay in the ground all year. In these frost-free areas, they truly act as perennials, growing larger and more impressive with each passing season. For everyone else, the "perennial" part of the plant’s life happens only if we take extra steps to protect it from the winter cold. You can compare your climate to our Hardiness Zone Map.
Understanding the "Tender Perennial"
In the gardening world, we often use the phrase "tender perennial" to describe plants like begonias. It is a helpful middle-ground term. It reminds us that while the plant has the potential to live for a long time, it is delicate when it comes to temperature.
Think of a begonia like a guest who loves a warm summer party but has no interest in staying for the winter snow. If you provide a warm place for that guest to stay when the temperature drops, they will be happy to come back to the party next year.
Because begonias are perennials at heart, they put a lot of energy into building strong root systems or storage organs like tubers. This energy reserve is exactly what allows us to "overwinter" them. By moving the plant or its roots into a protected environment before the first frost, we are simply helping the plant finish its natural perennial life cycle.
Key Takeaway: Begonias are perennials that are sensitive to cold. In most of the U.S., they are grown as annuals unless you bring them indoors or store their tubers for the winter.
Different Begonias, Different Life Cycles
Not all begonias are the same, and how you treat them as an annual or perennial depends on the variety you have in your garden. There are thousands of species, but we generally group the most popular garden types into three categories.
Tuberous Begonias
Tuberous begonias are some of the most spectacular plants we offer at Longfield Gardens. These begonias grow from a thick, brown, potato-like structure called a tuber. This tuber acts as a storage tank for energy, which is why tuberous begonias can produce such massive, double-petaled flowers that look like roses or camellias.
Because they have this tuber, they are the easiest begonias to keep as perennials. In the fall, the plant naturally begins to go dormant. You can dig up the tuber, store it in a cool, dry place, and replant it the following spring. Popular varieties like the 'Nonstop' series or the cascading 'Double Delight' are perfect examples of tuberous begonias that can provide beauty for many years if stored correctly. If you like this style of bloom, the Upright Double Begonias collection is worth exploring too.
Wax Begonias (Fibrous Begonias)
Wax begonias are the classic bedding plants you see in parks and garden borders. They have shiny, succulent leaves that are either green or bronze, and they produce small, prolific flowers in shades of red, pink, and white. These have fibrous root systems rather than tubers.
Most gardeners treat wax begonias as true annuals. They are inexpensive and grow very quickly, so it is often easier to plant fresh ones each spring. However, they are still perennials. If you have a favorite wax begonia in a pot, you can bring it inside before the first frost and keep it as a houseplant near a sunny window. They can easily live for four or five years in a stable indoor environment. For container-friendly options, see our Hanging Begonias collection.
Rex and Rhizomatous Begonias
These begonias are famous for their foliage rather than their flowers. Their leaves come in incredible patterns of silver, purple, swirling green, and deep burgundy. These plants grow from rhizomes, which are thick stems that creep along the surface of the soil.
Like wax begonias, these are frequently kept as houseplants year-round. In the garden, they serve as a stunning perennial groundcover in tropical zones, but in cooler climates, they must be brought inside. They are quite happy living on a coffee table or windowsill until the warm weather returns.
Where You Live Matters: USDA Hardiness Zones
Your local climate is the biggest factor in deciding whether your begonias are annuals or perennials. The USDA Hardiness Zone map is a tool we use to understand which plants can survive the winter in a specific area.
- Zones 9-11: If you live in places like Florida, Southern California, or parts of the Gulf Coast, your begonias are perennials. You can leave them in the garden year-round. They may slow down their growth in the winter, but they won't die back to the ground unless there is an unusual cold snap.
- Zones 2-8: For the rest of the country, begonias are annuals. The ground freezes in these zones, which would destroy the water-filled cells of a begonia plant. If you want them to return next year, you must intervene.
We time our shipping at Longfield Gardens based on these zones. We ensure your begonias arrive when the soil in your area is warm enough for them to thrive, typically about two weeks before the ideal planting time. This helps you get your "annual" season off to a strong start. You can read more on our Shipping Information page.
How to Overwinter Tuberous Begonias
If you have grown a beautiful pot of tuberous begonias and want to see them again next spring, you can follow a simple process to "save" them. This is the most practical way to treat these plants as perennials in a cold climate.
- Watch the weather: Wait until the first light frost kills the top of the plant. The leaves will turn black or shrivel. This tells the tuber it is time to go to sleep.
- Dig them up: Gently lift the tubers out of the soil. Be careful not to bruise or cut them, as this can lead to rot.
- Clean and dry: Shake off the excess soil and cut the stems back to about an inch above the tuber. Lay them out in a dry, shaded spot for about a week to "cure." This toughens the outer skin.
- Store safely: Place the cured tubers in a cardboard box filled with dry peat moss, sawdust, or shredded paper.
- Keep them cool: Store the box in a basement or garage where the temperature stays between 40°F and 50°F. It must be cool enough to keep them dormant but warm enough to prevent freezing.
What to do next:
- Check stored tubers once a month for soft spots.
- If a tuber feels mushy, discard it immediately so it doesn't affect the others.
- In early spring, move the tubers to a warm, bright spot to "wake them up" before planting.
"The magic of tuberous begonias is that the tubers actually get larger and produce more flowers as they age. Saving them for next year isn't just about saving money; it's about growing a more impressive plant."
Bringing Wax Begonias Indoors
Since wax begonias don't have a tuber to store, you have to keep the whole plant alive if you want it to act as a perennial. This is a great option for begonias grown in containers or hanging baskets.
Before the temperatures drop below 50°F at night, bring your pots inside. These plants are sensitive to the change in humidity and light, so they might drop a few leaves at first. Don't worry; this is a normal part of their adjustment.
Place them in a bright window that gets indirect light. Since the indoor air is much drier in the winter, you won't need to water them as often as you did outside. Wait until the top inch of soil feels dry before giving them a drink. By keeping them as houseplants, you are extending their life cycle and ensuring you have healthy, established plants to move back outside when spring arrives.
Right Plant, Right Place: Success in Any Season
Whether you treat your begonias as annuals or perennials, getting the basics right will ensure they look their best. Begonias are not difficult to grow, but they do have specific preferences. For a deeper dive into placement and maintenance, see our Best Growing Conditions for Begonias guide.
Light Requirements
Most begonias prefer "dappled" or filtered sunlight. In their native homes, they grow on the forest floor under the canopy of trees.
- Shade: They love it, but "deep shade" (where no light reaches) might lead to fewer flowers.
- Sun: Some modern varieties, especially certain wax begonias, can handle more sun, but in most cases, the hot afternoon sun will scorch their leaves. A spot that gets morning sun and afternoon shade is usually the "sweet spot."
Soil and Drainage
If there is one thing that will cause a begonia to fail, it is "wet feet." Begonias have succulent stems that hold a lot of water. If the soil stays soggy, the stems and roots will rot very quickly.
- Always use a pot with drainage holes.
- In the garden, ensure the soil is loose and airy. If you have heavy clay, mixing in some compost or peat moss can help water move through the soil more freely.
Watering Correctly
We recommend the "soak and dry" method. Water the plant deeply until water runs out of the bottom of the pot, then wait to water again until the soil feels dry to the touch. This encourages the roots to grow deep into the pot or ground in search of moisture, making the plant stronger and more resilient.

Simple Troubleshooting for Healthier Plants
If your begonia isn't looking as vibrant as you'd like, it's usually due to one of three things. Before trying complex fixes, look at these simple factors:
- Yellowing leaves: This is almost always a sign of overwatering. Let the soil dry out more between waterings.
- Leggy stems: If the stems are getting very long with a lot of space between the leaves, the plant is likely reaching for more light. Move it to a slightly brighter location.
- Few flowers: This can happen if the plant is in too much shade or if it needs a little "food." Use a balanced, water-soluble fertilizer once a month during the growing season to encourage more blooms.
Why Some Gardeners Prefer the Annual Approach
Even though begonias are perennials, many of our customers choose to treat them as annuals every year. There are several good reasons for this "fresh start" approach.
First, it allows for variety. One year you might want the fiery oranges and reds of the 'Nonstop Fire' tuberous begonias, and the next year you might prefer the soft, elegant pinks of 'Double Delight Blush Rose'. Treating them as annuals gives you the freedom to redesign your garden palette every spring.
Second, it saves time and space. Not everyone has a cool basement for storing tubers or a sunny windowsill for overwintering pots. For many busy gardeners, the simplicity of planting fresh, healthy bulbs or starts from us each spring is more enjoyable than the maintenance required to keep them through the winter.
Finally, young plants are often more vigorous. While older tubers can produce more flowers, young begonias often have a compact, tidy habit that looks perfect in flower beds and borders.
Creating a "Perennial Look" with Begonias
You can create a garden that feels like a permanent, lush paradise by pairing begonias with true perennials that share their love for shade. This creates a high-trust garden design where the begonias provide the "pop" of color and the other plants provide the structure.
Excellent companions for begonias include:
- Hostas: Their broad, cool leaves provide a perfect backdrop for the bright flowers of tuberous begonias.
- Ferns: The airy, feathery texture of ferns contrasts beautifully with the thick, waxy leaves of begonias.
- Heuchera (Coral Bells): These perennials come in various foliage colors that can complement or contrast with your begonia choice.
- Astilbe: Their tall, plumed flowers add vertical interest to a bed where begonias are providing low-level color.
By mixing these together, you get the best of both worlds: the reliability of hardy perennials and the nonstop blooming power of begonias.

FAQ
Can I leave my begonias in the ground over winter?
You can only leave begonias in the ground if you live in USDA hardiness zones 9, 10, or 11, where the ground does not freeze. In any other zone, the cold winter temperatures will kill the plant. If you want to keep them in colder zones, you must dig up the tubers or bring the pots indoors before the first frost. If you need help choosing the right timing, our How to Plant and Care for Begonias guide is a helpful next step.
How long do begonia plants typically live?
When grown as perennials in the right conditions, wax begonias can live for 4 to 5 years. Tuberous begonias can live even longer, as the tubers continue to grow and can be replanted for many consecutive seasons. If grown as outdoor annuals in cold climates without protection, they will only live for one growing season.
Do begonias need to be cut back for the winter?
If you are storing tuberous begonias, you should cut the stems back to about an inch above the tuber once the foliage has been hit by a light frost and turned yellow or black. If you are bringing a wax begonia inside as a houseplant, you don't need to cut it back, but you can trim off any leggy growth to keep it looking tidy.
Why did my stored begonia tubers rot?
Rot usually happens if the tubers weren't dried (cured) properly before storage or if the storage area is too damp. It is important to let them sit in a dry spot for a week after digging them up and to store them in a breathable material like peat moss or a cardboard box rather than a plastic bag. High humidity or moisture during their "sleep" period causes the tissue to break down.
