Introduction
Finding the perfect flower for a shady corner or a sunny patio is one of the most rewarding parts of gardening. Begonias are often the first choice for many home gardeners because they offer brilliant color and beautiful foliage with very little effort. Whether you are planting them in a hanging basket or using them to edge a garden bed, these plants provide a dependable splash of beauty from late spring until the first frost.
At Longfield Gardens, we enjoy helping people discover how versatile and beginner-friendly these begonia flower bulbs can be. Many gardeners ask whether a begonia is a seasonal plant or if it will come back year after year. The answer depends on your local climate and the specific type of begonia you choose to grow.
In this guide, we will explore the different types of begonias and explain how their growth habits change based on where you live. You will learn how to treat them as seasonal annuals, how to grow them as year-round houseplants, and even how to overwinter certain varieties. For more detail, see our How to Plant and Care for Begonias guide. Understanding the lifecycle of your begonias ensures you get the most out of these stunning plants every single year.
Defining the Seasonal Nature of Begonias
The word "seasonal" can mean different things in the world of gardening. For many people, a seasonal plant is an annual. This is a plant that completes its entire life cycle in one growing season and does not return the following year. Other gardeners use "seasonal" to describe plants that only bloom at a specific time, such as spring bulbs or fall chrysanthemums.
Begonias occupy a unique middle ground. In their native environments, which are mostly tropical and subtropical regions of Africa, Asia, and the Americas, begonias are perennials. This means they grow and bloom for many years in the wild. They thrive in warm temperatures and high humidity, often growing on forest floors where they receive dappled sunlight.
In most parts of the United States, however, begonias are treated as seasonal annuals. Because they are tropical plants, they cannot survive freezing temperatures. When the weather turns cold in autumn, the plants will naturally die back. For a gardener in a northern climate, the begonia is a seasonal guest that provides beauty throughout the summer months.
If you live in a frost-free region, such as parts of Florida, California, or Texas, you may find that your begonias live for several years in the landscape. Even in colder climates, you can extend the life of these plants by bringing them indoors. By understanding their tropical roots, you can decide whether you want to enjoy them for just one season or keep them as long-term companions.
The Different Groups of Begonias
To understand if your begonia is seasonal, you first need to identify which type you have. There are over 2,000 species of begonias, but most home gardeners interact with four main groups. Each group has a slightly different relationship with the seasons.
Wax Begonias
Wax begonias are the most common variety found in garden centers. They are named for their glossy, succulent-like leaves which can be green, bronze, or variegated. These are often sold in small packs and used as bedding plants to create a carpet of color.
Wax begonias are extremely dependable. They bloom continuously from the moment you plant them until the frost arrives. While they are technically perennials, almost everyone grows them as seasonal annuals. They are inexpensive and easy to replace each spring. They are also quite tough and can handle more sun than many other begonia types. For more on light needs, see Are Begonias Shade or Sun Plants?.
Tuberous Begonias
Tuberous begonias are known for their spectacular, rose-like flowers. These blooms can be quite large and come in vibrant shades of red, orange, yellow, and pink, including deep pink flowers. Because of their heavy blooms and trailing habits, they are favorites for hanging baskets and window boxes.
These begonias grow from a thick, potato-like structure called a tuber. This tuber is the plant's way of storing energy for a dormant period. Unlike wax begonias, tuberous begonias naturally want to take a break in the winter. In the fall, the foliage will yellow and drop off. This is a sign that the plant is entering its seasonal dormancy. You can save these tubers and replant them the following spring.
Rex Begonias
Rex begonias are grown primarily for their foliage rather than their flowers. Their leaves are works of art, featuring swirls of silver, purple, pink, and deep green. They are often used as "thriller" plants in mixed containers to add texture and drama.
Rex begonias are very sensitive to cold. Most gardeners use them as seasonal accents in the summer garden and then bring them inside to live as houseplants during the winter. They do not have a tuberous dormant phase, so they can keep their beautiful leaves all year if they stay warm and humid. For a broader look at begonia types, see All About Begonias.
Cane Begonias
Cane begonias, which include the famous "Angel Wing" varieties, have long, upright stems that resemble bamboo. They often have large, wing-shaped leaves with silver spots and clusters of drooping flowers. For a closer look at this group, see Angel Wing begonias.
These begonias are very popular as year-round houseplants. When grown outdoors, they are seasonal treats for the porch or patio. Like Rex begonias, they will continue to grow as long as the temperatures remain above 50°F. They are easy to move back and forth between the house and the garden as the seasons change.
Key Takeaway: Most begonias are tropical perennials that gardeners treat as seasonal annuals because they cannot survive frost. Identifying your specific type—Wax, Tuberous, Rex, or Cane—helps you decide how to care for it when the weather cools down.
The Hardy Begonia: A Perennial Exception
While most begonias are tender and seasonal, there is one notable exception: Begonia grandis, also known as the hardy begonia. If you are looking for a begonia that acts like a traditional garden perennial and returns every spring, hardy begonia is the plant for you.
Hardy begonias are generally reliable in USDA hardiness zones 6 through 9. This means they can survive winter temperatures that drop well below freezing. They feature beautiful heart-shaped leaves with red undersides and delicate sprays of pink or white flowers that bloom in late summer.
One interesting habit of the hardy begonia is that it is a late sleeper. It often does not emerge from the ground until late spring or early summer, long after other perennials have started growing. This makes them excellent companions for spring-flowering bulbs. As the bulbs fade away, the hardy begonias grow in to cover the space with lush foliage.
Hardy begonias have a clever way of spreading. In the fall, they produce tiny "bulbils" where the leaves meet the stems. These small beads fall to the ground and grow into new plants the following year. This allows the plant to naturalize and create a beautiful colony in a shady woodland garden.
Growing Begonias as Seasonal Annuals
Most people choose to enjoy begonias as seasonal annuals because it is simple and rewarding. You get months of flowers without the need for long-term maintenance. To get the best results from your seasonal begonias, following a few basic rules will ensure they stay healthy all summer long.
Timing Your Planting
Because begonias love warmth, timing is more important than almost any other tip. Do not be in a rush to plant them in the early spring. Wait until the soil has warmed up and there is no longer any danger of frost. In many regions, this is around the same time you would plant tomatoes, and our Hardiness Zone Map can help you check your local timing.
If begonias are planted in cold, wet soil, they may struggle to grow or develop root issues. They prefer nighttime temperatures to be consistently above 50°F. If a surprise late-spring cold snap occurs, it is a good idea to cover your plants or bring containers into the garage for the night.
Finding the Right Place
Most begonias prefer a spot with dappled shade or morning sun and afternoon shade. The hot, direct afternoon sun can sometimes scorch their leaves, especially for tuberous and Rex varieties. Wax begonias with bronze leaves are the most sun-tolerant and can often handle a full day of light if they are kept watered.
Drainage is the quiet winner when it comes to begonia success. These plants have fleshy stems that store water. If they sit in soggy soil, they can quickly rot. Whether you are planting in the ground or a pot, make sure the water can move away from the roots easily. Using a high-quality potting mix for containers is a simple way to ensure good drainage, and our Upright Double Begonias collection offers a range of bold forms for pots and beds.
Watering and Feeding
The best way to water begonias is to let the top inch of soil dry out before watering again. When you do water, do it deeply so the moisture reaches the bottom of the root ball. Avoid getting water on the leaves if possible, as this helps prevent powdery mildew.
Since seasonal begonias are asked to bloom heavily for several months, they appreciate a little extra food. A balanced, water-soluble fertilizer applied once a month during the growing season is usually plenty. This keeps the foliage lush and the flowers coming. If you want more planting guidance, see How to Plant Tuberous Begonias.
What to Do Next:
- Check your local frost dates before buying your begonias, and review our Shipping Information.
- Choose a location that offers protection from the harsh afternoon sun.
- Ensure your pots or garden beds have excellent drainage.
- Water only when the soil surface feels dry to the touch.
Transitioning Begonias for the Winter
If you have a begonia that you truly love, you don't have to say goodbye when the season ends. There are three main ways to handle your plants as winter approaches: saving the tubers, bringing the plants inside, or taking cuttings.
Saving Tuberous Begonias
Tuberous begonias are the easiest to save for the next season. When the leaves start to turn yellow in the fall, stop watering the plant. After the first light frost kills the top growth, dig up the tubers. Cut the stems off about an inch above the tuber.
Spread the tubers out in a dry, shaded area for a few days to let them "cure." Once the outer skin feels dry, brush off any remaining soil. Store them in a box filled with dry peat moss, sawdust, or shredded paper. Keep the box in a cool, dark place where temperatures stay around 40–50°F. In the spring, you can start them in pots indoors about six weeks before the last frost.
Bringing Begonias Indoors
Rex, Cane, and even Wax begonias can be moved indoors to live as houseplants. It is best to do this before the temperatures drop below 50°F. Sudden changes in temperature can cause the plants to drop their leaves in stress.
Before bringing them inside, check the plants thoroughly for any garden pests. You may want to give them a gentle rinse with a garden hose. Once inside, place them in a bright spot with indirect light. For more indoor care tips, a bathroom or kitchen often provides the humidity these tropical plants crave. Remember that indoor air is much drier than outdoor air, and the plants will grow more slowly in the winter, so they will need less water and no fertilizer until spring returns.
Taking Cuttings
If your outdoor begonia is too large to bring inside, you can take a small cutting to start a new, smaller plant. This is a fun and easy way to "clone" your favorite seasonal flowers.
Simply cut a 4-inch piece of stem that has a few leaves. Remove the lower leaves and place the stem in a glass of water or a small pot of moist potting soil. In a few weeks, roots will begin to form. By spring, you will have a healthy young plant ready to go back into the garden.
Using Begonias in the Landscape
Because begonias are so versatile, they can play many different roles in your seasonal garden design. Their variety in size and habit makes them a favorite for creative gardeners.
- Edging and Borders: Wax begonias are perfect for creating clean, colorful lines along a walkway or the front of a flower bed. Their compact growth habit keeps them looking tidy all season.
- Hanging Baskets: Trailing tuberous begonias or cascading pink begonias create a waterfall of color. They look beautiful on a porch where you can see the intricate flowers at eye level.
- Shade Brighteners: In a dark corner of the yard under a tree, a few white petals with pink edges can act like a spotlight, making the area feel bright and welcoming.
- Container Thrillers: A large Rex begonia with metallic silver leaves makes a stunning centerpiece for a pot, while bright red flowers add even more drama.
At Longfield Gardens, we have seen how a simple container of begonias can transform a space. Because they are self-cleaning, meaning the old flowers fall off on their own, they always look fresh without the need for constant deadheading. This makes them a low-maintenance choice for busy gardeners who still want a high-impact look.
Simple Care for Maximum Success
Gardening should be an enjoyable hobby, and begonias are designed to make it easy for you. If you focus on just a few basic needs, your plants will reward you with beauty all season long.
One of the most important things to remember is that begonias are "fleshy" plants. Their stems and leaves are full of moisture. This makes them somewhat drought-tolerant, which is a great relief if you forget to water for a day or two. However, this same feature makes them very sensitive to overwatering. If the soil stays like a sponge, the air cannot reach the roots, and the plant can suffer.
If your plant starts to look "leggy" or stretched out in mid-summer, do not be afraid to give it a quick trim. Pinching back the tips of the stems encourages the plant to grow more side branches. This results in a fuller, bushier plant with even more flowers. It feels like a small chore, but the reward is a much more beautiful display for the second half of the season.
Finally, keep an eye on the weather. Begonias are at their best when the air is warm and still. If you have a particularly windy spot, the large leaves of Rex or Cane begonias might get torn. Providing a little bit of shelter from strong winds helps the foliage stay pristine.
Key Takeaway: Begonias are successful when you match their tropical needs to your garden's environment. Focus on warmth, good drainage, and bright but indirect light to ensure your "seasonal" plants look their best from start to finish.
Conclusion
Begonias truly are one of the most flexible plants a gardener can choose. While they are technically perennials from the tropics, they serve us beautifully as seasonal annuals in most American gardens. Whether you treat them as a one-summer romance or bring them inside to enjoy for years, rich, velvety red flowers bring a level of color and texture that is hard to match.
By choosing the right variety for your light conditions and ensuring they have well-drained soil, you can enjoy a worry-free garden full of blooms. Remember that gardening is an experiment. You might find that saving tubers becomes a favorite winter hobby, or you might prefer the fresh start of new plants each spring. Both ways lead to a beautiful garden.
For the best results this season, we recommend starting with high-quality plants or tubers that are suited to your specific garden spots. At Longfield Gardens, we take pride in providing the 100% Quality Guarantee and support you need to make your garden dreams a reality.

FAQ
Do begonias come back every year?
In most parts of the United States, begonias do not come back on their own because they cannot survive freezing winter temperatures. They are considered tender perennials that are usually grown as seasonal annuals. However, the "Hardy Begonia" (Begonia grandis) is an exception and can survive winters in USDA zones 6 through 9, returning from the ground each spring.
Can I leave my begonias in the ground over winter?
You can only leave begonias in the ground over winter if you live in a tropical or subtropical climate (USDA zones 9–11) where there is no frost. In colder regions, the cold will kill the roots and stems of most begonias. If you have tuberous begonias, you must dig them up and store the tubers indoors if you want to keep them for the following year.
Is a begonia better as an indoor or outdoor plant?
Begonias are excellent in both roles! Many varieties, such as Rex and Cane begonias, are popular as year-round houseplants because they tolerate lower light levels. Outside, begonias thrive in the warm, humid weather of summer and are staples for shade gardens and patio containers. Many gardeners choose to move their plants outdoors for the summer and bring them back inside for the winter.
Why did my begonias stop blooming in late summer?
Begonias usually bloom non-stop, but they may slow down if they are stressed. The most common causes are extreme heat, underwatering, or a lack of nutrients. Make sure your plants are shielded from the hot afternoon sun and that the soil stays consistently moist but not soggy. A light application of balanced fertilizer can also give them the energy they need to keep flowering until the first frost.
