Begonia Maculata: Polka Dot Begonia Plant Care

Begonia maculata is a beautiful flowering perennial that belongs to the family of Begonia species.

The scientific name of this houseplant is the Begonia Maculata, while most people call it the Polka dot begonia.

The plant earned the name Polka Dot Begonia because of its deep olive-green leaves with white or pale pink dots.

The name is derived from the silvery-white polka dots on its leaves and from the shape of its stem.

So, while Begonia describes the shape of the plant, the word Maculata explains the beauty of the polka dot Begonia.

With a deep red underside, it is by far one of the most beautiful begonias.

In fact, according to urban legend, Christian Louboutin’s trademark red-heeled shoe was inspired by the plant’s underside.

The evergreen perennials hail from all parts of the world.

You can find these plants in their natural habitat in tropical forests in Asia, Mexico, South Africa, and Central America.

Although the plant needs moisture to grow, too much water may equally be dangerous.

This amongst many other factors makes the cultivation and maintenance of the plant a tedious task requiring care and precision.

Although an indoor plant can be placed outside during Summer make sure you transfer them indoors when the weather starts to cool down.

Though sunlight is a must, reduce the amount of direct sunlight.

The Polka Dot Begonia can be grown in pots, however, it does not grow beyond 5 feet (1.5 meters) in height and its asymmetric leaves spread out to about 8 inches (20 cm).

Unlike many indoor plants, the tropical plant may reach its optimum growth rates in very humid climates and moist soil.

The plant’s thick stems hold up well and you can grow a tall begonia by using a stake next to the plant.

Begonia Maculata is considered a cane begonia. These so-called cane begonias generally grow angel wing-shaped leaves that are asymmetric.

These leaves sprout from long stems that look like bamboo shoots. These thick stems detain some water so they don’t like super wet conditions.

During their growing season in the Summer, these beautiful plants bloom gorgeous flowers.

In indirect light, the cascading white flowers bloom tend to turn pale pink with yellow pigments in the center of the flower.

You should fertilize Maculata Begonia biweekly to boost the quality of leaf growth.

However, pay close attention to the quantity of fertilizer being used.

It’s best if you only use half of the dosage prescribed on the package to prevent overfertilizing your plant.

Propagating Begonia Maculata

Propagating begonias from seedlings requires a lot of patience. We highly recommend propagating by leaf cuttings or stem cuttings.

Propagation from leaf cuttings

To grow new begonia plants from leaf cuttings, simply cut a few leaves from your mother plant.

Take the leaves and lay them flat. With a clean knife, cut them into wedge shape leaving at least 1-inch of the stalk that is connected to the stem.

Make sure each wedge has a vein in it. Each wedge will eventually grow into a new plant.

At this stage, you have two choices. You can stick the leaf-cutting (the wedges) into the soil (or other types of growing medium like peat moss), or propagate leaf cuttings in water.

Leaf Cuttings in Soil

Place the pot of leaf cuttings in a warm and bright location – away from direct sun.

Keep the leaf-cutting moist but don’t overwater them as you don’t want root rot.

New roots should sprout in about 3 to 4 weeks.

After about 6 weeks, you can transplant the new baby plants to a new pot or your outdoor garden.

Leaf Cuttings in Water

Simply take your leaf cuttings and suspend them in water.

Once you notice roots sprouting to about a half-inch, you can transplant them into a new pot.

Propagation from stem cuttings

Begonia Maculata will grow by stem cuttings commonly known as rhizomes.

Rhizomes are the thick and long stems that are span under the soil.

Begin by cutting a piece of the stem (or rhizome). About 1-inch (2 to 3 cm) is all you need.

Place the stem cutting into potting mix or peat moss.

Make sure the soil is moist and not overly wet.

Keep the stem cuttings in a bright and warm area – away from direct sun.

Roots should start to sprout in about 5 to 7 weeks.

You can then transplant them into a new pot after this time.

Best time to propagate Begonia Maculata

The best time to propagate is during the growing season. The growing season is generally the summertime.

This will give the best chance for your new plants to sprout roots and grow into new plants.


It is important to prune your plant regularly to produce a fuller and bushier plant.

Spring and Summer are the best periods for pruning. Take out the wilted flowers and leaves with crispy leaf tips.

Pick out overgrown branches a few inches above the bud so that the buds will produce new stems.
