Begonia maculata grows naturally in Southeastern Brazil, just like many of the plants we like to keep in our homes, like Ctenanthe, Maranta, and Calathea makoyana. It has also been brought into a few other Central and South American countries. You can find it as far north as Mexico and as far south as Argentina.
In its natural habitat, this species grows in rainforests. Its natural growth zone in Brazil is called the Atlantic rainforest, and it has higher elevations, stable temperatures, and a wet climate.
Did you know? Begonia maculata, like other Begonias, is traditionally used as a medicinal plant. In Chinese medicine, it’s described to be a diuretic and detoxifying agent.
Begonia maculata is a cane Begonia. This is a subgroup within the genus known for its semi-shrubby growth pattern and cane-like stems. Cane Begonias have joints on their stems that resemble bamboo, and flowers bloom from these joints. Their elongated leaves are sometimes referred to as “angel wings. ” (You’ll sometimes see the plant labeled as an angelwing Begonia. ) In the wild form, these leaves are solid green or feature some light spotting.
The plant we call the polka dot Begonia, which is actually a cultivar called Begonia maculata ‘Wightii, was grown in a special way. The name comes from the much bigger dots on its dark green leaves. This is a really beautiful and dramatic plant. The dots shine silvery in the sun, and the backs of the leaves are light to deep red.
You wouldn’t grow this type of Begonia just for its flowers, but if you take good care of it, it does have pretty little blooms. The flowers form in clusters and are white to pink, with bright yellow stamens.
Begonia maculata looks pretty nice in its wild form, but nurseries have been able to make a lot of different cultivars by carefully selecting which plants to grow. The most well-known is Begonia maculata ‘Wightii,’ also called the polka dot Begonia. The species became very popular as a houseplant because of this variety, but it’s not the only one.
The backs of a “Wightii” plant’s leaves are dark red (though they can get lighter if the lighting isn’t good), and the leaves’ edges are never touched by dots that are all the same size. Its flowers are white.
Besides these “pure” maculatas, there are also some hybrids that you can find, but I’ve never seen one in person. Figuring out which cultivar or hybrid Begonia you’re dealing with is pretty hard with Begonias in general, and Begonia maculata is no different.
It’s important to remember that none of the above varieties are as common as the ‘Wightii’ cultivar, and most people won’t bother looking for them because they’re not that different. If you want to grow one of these, you’ll probably need to buy cuttings from people who like houseplants.
Did you know? You’ll also see plants referred to as Begonia maculata ‘Tamaya’. The “Tamaya” part doesn’t name a cultivar; it names the way the plant is grown! Most cane or angelwing Begonias can be grown in “Tamaya” form, which makes the plant look like a small tree.
With its distinctive polka-dotted leaves and cascading growth habit, begonia maculata has become a beloved houseplant. However, few people are familiar with where this species originates and how it grows naturally in the wild. Begonia maculata is endemic to the Atlantic coastal forests of Brazil, where it thrives in the warm, humid climate. Understanding the native habitat of begonia maculata provides insight into properly caring for it as a houseplant.
Natural Range and Distribution
Begonia maculata is native to the Atlantic Forest (Mata Atlântica) biome located along the eastern coast of Brazil. This biodiverse region stretches from Rio Grande do Norte state in the north to Rio Grande do Sul state in the south. Within the Atlantic Forest, begonia maculata grows in shady, forested areas in the Brazilian states of Espirito Santo and Rio de Janeiro.
Specifically. this species has been documented in the following protected areas
- Reserva Biológica de Sooretama, Espirito Santo
- Reserva Natural Vale, Espirito Santo
- Parque Estadual da Serra da Tiririca, Rio de Janeiro
Though endemic to Brazil begonia maculata has been introduced as an ornamental houseplant to parts of Central America, the Caribbean and Argentina. However, it remains restricted to forested regions of southeastern Brazil in the wild.
Natural Habitat and Ecology
In its native range, begonia maculata grows as an understory plant in shaded, humid rainforests and coastal forests. It thrives in the filtered light and constant moisture of the forest floor. Begonia maculata occurs at elevations from sea level to around 800 meters.
Plants grow terrestrially on the ground and on decomposing wood and humus. They flourish in moist, well-draining, acidic soil rich in organic matter. Thick layers of leaves and decomposed plant material help retain soil moisture.
The red-purple undersides of the leaves likely serve as camouflage in the dim forest understory. This helps protect the plant from herbivores. The spots may also help break up the leaf outline.
In the wild, begonia maculata displays a spreading, creeping habit. The slender stems extend along the rainforest floor, rooting where nodes touch the ground. This allows the plant to efficiently access water and nutrients.
Threats and Conservation
The Atlantic Forest has suffered immense habitat destruction over the past 500 years. Agricultural expansion, logging, urbanization, and fragmentation have reduced the original forest cover by over 85%. Most remaining patches are small, isolated fragments. This puts endemic species like begonia maculata at risk.
While the polka dot begonia has a relatively widespread distribution in southeast Brazil, its fragmented forest habitat continues to decline. The IUCN Red List categorizes begonia maculata as a species of Least Concern, meaning it is not currently vulnerable to extinction. However, ongoing habitat loss combined with collection for the ornamental plant trade may threaten some populations.
Protected areas play a vital role in conserving both begonia maculata and the incredibly biodiverse Atlantic Forest. Continued preservation of existing habitats and forest restoration efforts are needed to ensure the survival of this unique biome and its many endemic plant species like the charismatic polka dot begonia.
Caring for Begonia Maculata as a Houseplant
When grown indoors, begonia maculata retains many of the preferences and traits it displays in its natural setting. To keep your polka dot begonia healthy and thriving:
-
Site in bright, filtered light to mimic the rainforest understory.
-
Water frequently to recreate the moist, humid habitat. Allow soil to dry out slightly between waterings.
-
Use a well-draining potting mix and avoid overwatering.
-
Maintain high humidity around the plant.
-
Keep temperatures between 60-75°F.
-
Prune leggy growth to encourage a compact shape.
Understanding where begonia maculata originates provides valuable insight into recreating the conditions it needs to prosper as an indoor plant. By looking to its native habitat, you can unlock the secrets to growing a happy, healthy polka dot begonia in your home.

Common questions about Begonia maculata care
Don’t panic! It happens to the best of us. If your Begonia isn’t shocked from being moved (which can happen if you bring a new one home) or from being outside in the cold, you should look at how often you water it.
It may dry out a little more slowly than in the summer, so your plant will need less watering. Is it winter? In summer, you may have to water twice as often, which means you may have waited too long.
Caring for Begonia maculata
You should keep your polka dot Begonia warm and bright. This is because most jungle plants like it that way. Put the plant on a windowsill or close to one. These plants are sometimes called low-light plants, but they don’t need that much light.
It will quickly get leggy and lose some of its beautiful leaf color if it isn’t getting enough light, which is a shame because it is such a beautiful plant.
Your polka dot Begonia can handle some direct sunlight inside as long as it doesn’t get too much. You can keep it in a higher-light area of your home, but give it a few weeks to get used to it first. If you don’t, you may see the leaves turning brown and crispy from the extra light.
It stays at least 70°F all year long in the places where this species of Begonia blooms naturally. This means that your plant should be kept at room temperature. Keep it away from drafty windows, air conditioners, heaters, and anything else that could change the temperature. Begonia maculata is prone to leaf loss when unhappy.
My Begonia maculata does well in temperatures around 57°F, but only when there is a lot of humidity (75% or more). I wouldn’t let temps drop much lower, though.
This is where things go wrong for many new Begonia fans, because these plants are pickier than most about how much water they get in the soil.
Most people often water their plants too much, which can cause leaves to fall off.
If you often forget to water your polka dot Begonia (like I do, whoops!), you may also lose leaves and notice brown tips on their leaves.
Overwatering usually makes the leaves turn sickly yellow before they fall off, while underwatering can make leaves fall off that look perfectly healthy.
So how do you keep these guys happy? Light is a big part of it. A houseplant that receives plenty of light will be a lot more forgiving in terms of watering. Other than that, it’s a matter of keeping the soil lightly moist; you can let the top inch or two dry out before watering again. (Use a moisture meter to help you determine moisture levels.)
Don’t worry if your polka dot Begonia drops a few leaves while you figure out its watering needs. It happened to mine as well, but it looks great now that we’ve come to an “understanding. ”.
Another factor many struggle with is humidity. Cane Begonias like this one are native to the tropics, where it rains plenty and humidity is very high all year round. Our homes? Not so much, especially in winter. You may want to invest in a humidifier to keep things above 50 percent humidity if you really want to see your tropical houseplants thrive. An inexpensive digital hygrometer (this is the one I use) can also help you determine your home’s relative humidity.
Although polka dot Begonias like some moisture, their soil should never be soggy. If the soil gets too wet, the roots will rot and the plant will die. These guys don’t care much about the soil mix and will do fine in regular houseplant potting soil, but you should add some gritty material to help it drain. I think you should loosen up your potting soil by adding 10 to 20 percent perlite, orchid bark, or pumice.
As for planting, anything goes, as long as the planter has a drainage hole in the bottom. This species of begonia doesn’t tend to grow very big roots, so you don’t need a big pot.
Recommended products for Begonia maculata plant care:
Cane Begonias aren’t heavy feeders, but these guys will still definitely appreciate a regular dash of fertilizer. Water your plants once or twice a month during the growing season and use a liquid houseplant fertilizer that has been diluted in water to half its strength.
Stop feeding your polka dot Begonia during winter. It won’t be able to use the fertilizer you give it, and giving it too much can make the brown leaf tips that Begonia fans hate so much.
Recommended fertilizers for Begonia maculata:
Begonia maculata is a species that does benefit visually from the occasional pruning in many cases. Even when the plant has a lot of light, it may send out stems that are too long and thin, which takes away from its bushy look.
No matter! Wait until the next growing season rolls around (spring or summer). Then, put the stem where you want it and cut it with clean pruning shears. You can either root it in water before planting it or just put it back in the planter. It should keep growing as usual and help keep your polka dot Begonia looking full.
That is the question: should you divide or repot your polka dot Begonia if it has grown too big for its pot? Most of these plants have multiple stems that were planted together at the nursery. You can choose to separate some of these stems and pot them up separately.
You can just take the plant out of its pot, separate a few stems, and put the rest of it back in the pot with some new soil. The stems you cut off will already have roots, so you can put them in a pot and they’ll keep growing normally.
You can move your plant to a new pot in one piece in the spring or summer. Choose a planter that’s an inch or so larger in diameter than the previous one.
Propagating Begonias, including the polka dot Begonia, really couldn’t be easier. The division method discussed above is one of the easiest ways to do it. You could also use the method I talked about in the section on pruning, which involves putting the cut pieces (which are really stem cuttings) in water or soil to grow roots.
Did you know? Technically a Begonia stem cutting doesn’t even have to include leaves. You can cut the canes into pieces at least an inch or two long and root them in wet sphagnum moss or your chosen medium. The section can grow new roots or leaves as long as it has an eye, which is a bump that roots or leaves can grow from.
