Introduction
If you have ever admired the lush, cascading greenery of a hanging basket or the elegant reach of a flowering vine, you know how much vertical interest adds to a garden. Begonias are often the go-to choice for shaded corners because of their brilliant colors and interesting leaf patterns. Many gardeners think of them as tidy, mounded plants, but there is a fascinating group of begonias that breaks this mold by reaching upward and outward.
At Longfield Gardens, we enjoy helping people discover new ways to bring beauty into their homes and yards. While most common varieties stay close to the ground, certain types of begonias have a unique vining habit. These plants offer a wonderful opportunity to experiment with vertical gardening in areas where traditional sun-loving vines might struggle.
In this guide, we will explore which begonias have climbing tendencies and how you can help them look their best. Whether you want a plant that spills over the edge of a container or one that climbs a moss pole, understanding these growth habits is the first step. While not all begonias are climbers, the varieties that are can transform your indoor or outdoor garden spaces. For a broader overview, see our All About Begonias guide.
What Are Trailing-Scandent Begonias?
When asking if begonias can climb, the answer lies in a specific group called "trailing-scandent" begonias. In the world of plants, "trailing" refers to stems that grow along the ground or over the side of a pot. "Scandent" is a botanical term that means climbing. This group is relatively small compared to the thousands of other begonia species, but they are prized for their versatility.
These begonias grow much like a vine. Instead of forming a tight, bushy clump, they produce long, flexible stems with significant space between the leaves. This space is called an "internode." In the right conditions, these stems can reach lengths of eight feet or more. Because their stems are quite pliable, they can either hang downward or be encouraged to grow upward against a support.
Unlike some vines that have "suckers" or "glue" to stick to walls, or tendrils that wrap around wires, climbing begonias are "scramblers." They grow by leaning on or weaving through other plants and structures. To make them truly "climb" in a home garden setting, they usually need a little bit of help from you to stay upright.
Key Takeaway: Climbing begonias belong to the trailing-scandent group. They are natural scramblers that can grow several feet long, making them perfect for vertical training or hanging displays.
Top Varieties for Climbing and Trailing
If you want a begonia that moves beyond a simple pot, you need to look for specific varieties. These plants are often found in specialty nurseries or through collectors, but they are becoming more popular for indoor plant lovers. For help identifying begonia types, our begonia identification guide is a useful next step.
Begonia solananthera
This is perhaps one of the most beloved climbing begonias. It is famous for its spicy, sweet fragrance, which is a rare treat in the begonia world. It produces heart-shaped, apple-green leaves and clusters of white flowers with bright red centers. It blooms most heavily in late winter and early spring, providing a much-needed burst of life when other plants are dormant.
Begonia radicans
Often called the "Shrimp Begonia," this variety is known for its profuse, deep coral flowers. It has a graceful branching habit and stems that are easy to manage. It is an excellent choice for someone new to trailing begonias because it is quite resilient and fills out beautifully when given enough light.
Begonia glabra
This was one of the first climbing begonias ever discovered. It features glossy green leaves and small, delicate white flowers. In its natural tropical habitat, it is often found growing as an "epiphyte," which means it grows on the surfaces of other plants or rocks rather than in the soil. This makes it a great candidate for growing on a totem or a moss-covered pole.
Begonia fagifolia
If you are looking for something with a unique texture, this species from Brazil is a great choice. It has hairy leaves and stems that grow in a distinct zig-zag pattern. Because the stems are somewhat sturdy, it is one of the easier varieties to train up a post or a small trellis.
How to Support Your Climbing Begonias
Since climbing begonias do not have their own "gripping" mechanisms like ivy or clematis, they require a support structure and a bit of guidance to grow vertically. Choosing the right support depends on the look you want to achieve. For a broader look at planting styles and flower forms, see our growing double begonias guide.
Using Totems and Moss Poles
A moss pole or a coir totem is one of the best supports for trailing-scandent begonias. These poles are made of wood or plastic wrapped in organic material that holds moisture. Because many of these begonias are naturally epiphytic, they love the humid environment of a moss pole. You can gently secure the long stems to the pole using soft garden twine or plant clips. Over time, the plant will grow upward, covering the pole in lush foliage.
Trellises and Frames
A small wooden or wire trellis can work well for varieties with slightly stiffer stems, like Begonia fagifolia. As the stems grow, weave them through the slats of the trellis. This creates a "wall" of leaves and flowers. This method is particularly effective for decorating a porch or a bright indoor corner.
Hanging Baskets
If you prefer the "trailing" part of the trailing-scandent habit, a hanging basket is the easiest way to go. Gravity does the work for you. In a basket, these begonias will grow outward and then spill over the sides, creating a curtain of green. This is a very natural way for these plants to grow and often results in the most flowers.
Simple Steps for Training Your Begonia
- Choose your support: Pick a moss pole, trellis, or post that fits your space.
- Plant at the base: Place your begonia in the pot so the stems are close to the support.
- Secure gently: Use soft ties to attach the longest stems to the support.
- Check regularly: As new growth appears, continue to tie it up every few inches.
- Pinch for fullness: Snip off the very tips of the stems to encourage the plant to branch out.
Essential Care for Climbing Begonias
To get the best growth out of your climbing begonias, you need to match their care to their natural tropical origins. They are not difficult to grow, but they do have a few preferences that make a big difference in how they look. If you want to compare planting options, our begonia collection is a good place to start.
Light Requirements
Light is the most important factor for these plants. They need plenty of bright, indirect light to thrive. If the light is too low, the space between the leaves (the internodes) will get very long and the plant will look "leggy" or thin. However, avoid the harsh midday sun, which can scorch their delicate leaves. A spot near an east-facing or north-facing window is usually ideal.
Watering and Humidity
In their native rainforests, these plants enjoy high humidity and consistent moisture. However, "moisture" does not mean "soggy soil." Drainage is the term we use to describe how fast water leaves the soil. Begonias have shallow roots and can easily rot if they sit in water for too long.
A good rule of thumb is to wait until the top inch of soil feels dry to the touch before watering again. If you are growing your begonia in a hanging basket, it may dry out faster than a plant in a standard pot. If you are just getting started with the basics, the All About Begonias guide covers general care well.
Soil and Potting
Because their roots are shallow, climbing begonias do best in "azalea pots" or shallow containers rather than deep, heavy pots. Use a potting mix that is "open," meaning it has plenty of perlite or peat moss to allow air to reach the roots. A soil pH between 5.0 and 6.5 is the "sweet spot" for most begonias.
Fertilizer
During the active growing season (spring and summer), your begonias will appreciate a regular feeding. We recommend using a balanced, water-soluble fertilizer. As the flowering season approaches, switching to a formula higher in phosphorus can help encourage more blooms.
Key Takeaway: Success with climbing begonias comes down to bright indirect light, shallow pots with excellent drainage, and a little bit of humidity.
Pruning and Pinching for a Better Shape
One of the most common mistakes with climbing or trailing begonias is letting them grow too long without any intervention. Because they have a vining habit, they can eventually become a single, long "string" with very few leaves near the base. For a fuller look, our begonia identification guide also helps you spot growth habits quickly.
Pinching is a simple technique where you use your fingernails or a small pair of snips to remove the very tip of a growing stem. When you remove the tip, the plant is forced to send out new stems from the "nodes" (the bumps on the stem where leaves grow). This results in a much fuller, bushier plant with more branches to train up your support.
For varieties with long spaces between the leaves, try cutting the stems back after the third or fourth leaf. This keeps the plant compact and prevents it from looking sparse. If your plant is already very long and bare at the top, don't be afraid to do a heavier prune. Begonias are quite resilient and will usually bounce back with fresh, vigorous growth.
Not All Begonias Are Climbers
It is helpful to know that while some begonias climb, many of the most popular types do not. If you are looking for a vertical grower, make sure you aren't accidentally buying a mounding variety. For more detail on growth habits, our growing double begonias guide is a helpful companion.
Wax Begonias (Semperflorens)
These are the common bedding plants you see in parks and garden borders. They are fibrous-rooted and grow in neat, round mounds. They are wonderful for color but will never climb or trail.
Rex Begonias
These are grown primarily for their stunning, colorful foliage. They grow from rhizomes (thickened stems that horizontal along the soil surface). While they are beautiful, their growth habit is short and compact.
Tuberous Begonias
These are known for their massive, rose-like flowers. While some tuberous varieties are "pendula" (meaning they weep downward), they do not have the long, vining stems needed to climb a trellis. They are best suited for hanging baskets where they can drape over the edges.
Cane Begonias
Also known as "Angel Wing" begonias, these have tall, upright stems that look like bamboo. While they can grow quite tall (sometimes 5 or 6 feet), they are self-supporting and grow straight up like a shrub rather than vining like a climber.
| Begonia Type | Growth Habit | Best Use |
|---|---|---|
| Trailing-Scandent | Vining / Climbing | Totem poles, trellises, hanging baskets |
| Wax Begonia | Mounded / Bushy | Garden beds, edging, containers |
| Rex Begonia | Low / Spreading | Houseplants, shade containers |
| Cane Begonia | Upright / Tall | Large indoor pots, focal points |
| Tuberous | Mounded or Weeping | Hanging baskets, window boxes |
Using Climbing Begonias in Your Home and Garden
Because most climbing begonias are tropical, they are usually grown as houseplants in the United States. However, they can enjoy a "summer vacation" outdoors once the weather is consistently warm. For planting inspiration, see the begonia collection.
Creating an Indoor Jungle
Climbing begonias are perfect for adding height to an indoor plant collection. Most houseplants stay at the same level on a shelf or table. By training a begonia up a moss pole, you draw the eye upward and make your indoor garden feel more layered and lush. They look particularly striking in a bright bathroom where the natural humidity keeps their leaves looking fresh.
Summer Patio Displays
If you live in a climate where summers are humid and warm, you can move your trailing begonias outside to a shaded porch or patio. They look beautiful growing up the pillars of a porch or hanging from the limbs of a large tree. Just remember to bring them back inside before the evening temperatures drop below 60°F. If you want more planting details, our All About Begonias guide explains the basics.
Combining with Other Plants
Climbing begonias play well with others. You can plant a trailing begonia at the base of a larger, upright plant like a Monstera or a Philodendron. The begonia will act as a "living mulch," covering the soil and eventually winding its way up the same support as the larger plant. This creates a stunning, multi-textured display.
Troubleshooting Common Issues
Even though gardening should be a rewarding and enjoyable activity, you might occasionally run into a small hurdle. Most begonia issues are easily fixed with one or two small changes. For more general care and placement ideas, the begonia identification guide is a useful reference.
- Paling Leaves: If the leaves start to look washed out or pale, the plant might be getting too much direct light. Move it a few feet away from the window or further into the shade.
- Stretching Stems: If the space between the leaves is getting very long and the plant looks thin, it is likely looking for more light. Move it to a brighter spot.
- Dropping Leaves: This is often a sign of a sudden change in temperature or a draft. Keep your begonias away from air conditioning vents or drafty doors.
- Brown Edges: This usually means the air is too dry. You can increase humidity by placing the pot on a tray of pebbles filled with water or by grouping several plants together.
Conclusion
Climbing begonias are a hidden gem for any gardener looking to add vertical beauty to shaded areas. While they aren't as common as the mounded wax begonias we see every spring, the trailing-scandent group offers a unique vining habit that is both elegant and versatile. Whether you choose the fragrant Begonia solananthera or the colorful Begonia radicans, these plants will reward you with interesting foliage and delicate blooms.
At Longfield Gardens, we believe that gardening is most successful when you get the basics right.

FAQ
How fast do climbing begonias grow?
In the right conditions with plenty of bright light and warmth, climbing begonias can grow quite quickly. Some varieties can add several inches of length to their stems in a single month during the peak growing season. Regular feeding and consistent moisture will help support this vigorous growth.
Do climbing begonias need a trellis?
While they don't strictly need a trellis to survive, they do need some form of support if you want them to grow upward. Without a trellis, pole, or post, the stems will naturally trail along the ground or hang downward from a pot. Providing a support allows you to showcase their unique vining habit. For general plant selection, see our begonia collection.
Can I grow climbing begonias from cuttings?
Yes, climbing begonias are very easy to propagate from stem cuttings. When you "pinch" or prune your plant to keep it bushy, you can take those cuttings and place them in water or a light potting mix. They usually develop roots within a few weeks, allowing you to start new plants for your home or to share with friends.
Are climbing begonias toxic to pets?
Like most members of the begonia family, climbing begonias contain calcium oxalates, which can be toxic if ingested by cats or dogs. It is always a good idea to keep these plants out of reach of curious pets. Because they grow so well in hanging baskets or on high shelves, they are easy to keep safely away from animals.
