Begonia types are extremely popular plants cultivated in every region of the world regardless of the type of climate.
This is not surprising to hear because not only are they aesthetically pleasing, but they are also easy to grow and suitable for indoor and outdoor cultivation.
Moreover, several plants are used for their medicinal purposes in their native lands and there is even Begonia tea made from the Chinese species B. fimbristipula.
How Begonia Got Its Name?
This genus has a somewhat confusing history of how it got the name Begonia.
Although three other names had been previously published for the species of this genus, the French Botanist Charles Plumier named the genus Begonia to honor Michel Begon who had recommended him to King Luis XIV of France for the position of plant collector in the French Caribbean.
So, this is the name that was also officially adopted by Linnaeus in his Species Plantarum of 1753.
Natural Habitats of Begonias
Begonias are naturally found throughout much of tropical and subtropical Africa, Asia, and America, especially humid forests of South America and mainland Asia. Through tropical, Australia is not home to begonias.
Distinctive Characteristics of Begonia Types
Begonia includes more than 1,000 species of foliage and flowering plants.
Begonia plant enthusiasts like to group begonias by growth into fibrous, trailing, shrub-like, rhizomatous, thick-stemmed, or tuberous, and by habit into angel-wing, rex, cane, or semperflorens.
Tuberous begonias have a tuber and if grown in the ground, they should be dug up, dried, and stored until the winter passes. Rhizomatous begonias have rhizomes around the soil surface, whereas rex begonias are immediately identified by their unique foliage.
However, there are some hybrid varieties that exhibit a combination of the traits that are typical to two or three groups. B.diurna is one such variety, fibrous with cane-like stems.
Begonias are especially prized for their charmingly colored and intricately patterned foliage. As such, they can be used as focal points or grouped together to create a calming oasis.
The leaves are usually oblique, asymmetric, and ear-like, where other varieties have fern-like leaves. Besides, the vein patterns also differ and may be palmate, palmate-pinnate, or pinnate.
Some compelling foliage patterns are exemplary of B.maculata, an angel wing, cane-like variety, as well as any species of the group Rex begonias.
Some varieties have hairy leaf surfaces and some African species take the form of star-shaped forms. Usually, the arrangement of leaves is alternate and most have several leaves, but some have only one or two like B. dioica.
As for foliage, there is an enormous variety of flower arrangements. Some species have terminal inflorescences which means that flowers form at the ends of the branches, whereas others have axillary inflorescences, which means that flowers appear along the length of the branches.
The flowers are always unisexual, meaning that there are both male and female flowers. Color variations are also immense and there can be yellow, orange, or red species.
The scent is pleasant, most noticeable on sunny days in the morning. Female flowers have a stronger scent and they attract insect pollinators.
The most powerfully scented is Begonia intergerrima that has a sweet, spicy smell. Other varieties are B.egregia, B. roxburghii, and B.lubbersii.
Do Begonias Come Back Every Year?
Begonia includes annuals and perennials.
Annuals complete their cycle after one growing season, which means that you plant the seeds and a baby plant emerges, produces flowers, and yields new seeds, an indicator that their life cycle is finished. However, you can get the plant to bloom for a longer period by deadheading.
Perennials live for more than 2 years and do not normally produce flowers in the first year, so they live longer.
Growing Habit – How Big Do Begonias Get?
The growth of begonia plants may be upright, climbing, or scrambling. Some plants are extremely short because they have aerial stems and rhizomes or tubers, whereas other varieties can reach up to 3.5m in height.
Consider the ultimate growing size of the variety you wish to grow and decide upon the site for site accordingly.
Where Should I Plant Begonias?
Begonia species are extremely versatile growers. Indoors, they perform very well in a pot or a basket, while some species that prefer higher humidity like B.semperflorens can be cultivated in large, enclosed terrariums, which makes them an even more attractive display.
They can be grown in greenhouses outdoors and some species like B.masoniana are great bedding plants and most varieties make great hanging-basket plants. All varieties can be moved outside in the warmer months, provided that you find a spot that receives bright shade.
Meet the Most Popular Begonia Types
Otherwise called the Painted Leaf Begonia, this creeping rhizomatous species was first noticed in northeast India.
Begonia rex has very large, burgundy leaves that are slightly hairy and adorned with peculiar patterns in different color combinations ranging from wine-red, green, and bronze.
The blooming period is in winter and the flower blooms are lighter than the leaves, with yellow centers.
Bonus care tip: Add peat moss or leafmold to the standard potting mix and find a spot where the plant will receive bright light and slightly higher humidity. The daytime temperature should be around 20 degrees and winter temperatures should be maintained above 13 degrees C. Propagate from seeds, leaf wedges, or leaf cuttings. If you know how to take care of Begonia rex, it is very rewarding to have it in your collection.
Tuberous Begonia tuberhybrida blooms in summer, giving you a splash of colorful flowers. The stems are somewhat succulent, the leaves dark green and you can even buy it as a mature plant.

How Do You Care for Begonias?
Before deciding upon the care routine that you are going to follow, do some research about the growing requirements of the plants you want to cultivate. Put special focus on the ideal home for them. Is it a pot, a hanging basket, a large jar or a terrarium, a greenhouse or simply, ground?
That will largely dictate the routine you are to adopt. Terrariums are ideal for small, compact varieties that need high humidity. Growing plants in a terrarium means less frequent watering, but the addition of grow lights. Yet again, larger, messy, and free-flowering varieties make the best displays in hanging containers. That’s why you’ll have to find a spot that receives light shade. In greenhouses, you will have to install fans to minimize temperatures.
In all cases, you will have to adjust the environmental conditions in a way that suits your plants.
Light, Temperature, and Humidity
These three variables are closely connected. Ideal temperatures are in the range of 13 to 29 degrees C during the day, that is, lower during nighttime.
The majority of begonias require a relative humidity between 40 and 60 percent. To achieve this level, you can either group the plants or buy a humidifier. Don’t mist the leaves.
Do begonias like sun or shade?
Light is the trickiest part here because begonias need different amounts of light. Too little light makes the foliage paler, whereas too much sun causes it to develop red or purple pigmentation on the leaves. It is safer to lean on the shadier side and increase the light intensity if you notice any signs.
For terrarium-grown varieties, keep grow lights on for 14 hours a day.
For standard cultivation, choose a shallow pot in a slightly acidic, well-aerated medium. You can also add sand, grit, bark, perlite, and moss.
The soil for greenhouse cultivation should be comprised of sphagnum peat, grit, bark, and limestone. Also, add some slow-release fertilizer.
On the other hand, the soil mix for terrarium cultivation should consist of charcoal pieces to line the base, sterilized and boiled sphagnum moss, combined with perlite. Avoid watering immediately after planting.
Transplant when the roots fill the containers.
Do Begonias Need a Lot Of Water and Fertilizer?
To determine how much water your begonias need, take into account the climate, growing medium, as well as the pot itself.
Generally speaking, water begonias grown in pots when the top surface becomes dry. Allow the excess water to drain out from the bottom. Use warm water, never cold.
Keep in mind that terrarium begonias don’t require frequent watering. Approximately once a month or even less than that is enough. Always use distilled water or rainwater. Check the moisture with your hands and if you overwater, remove the cover and let it dry.
On the other hand, be careful with rhizomatous, rex, and tuberous begonias in the state of dormancy. Make sure not to overwater. Symptoms of overwatering include leaf drop, root rot, and wilted stems.
Feed regularly during the active development with a 20-10-20 mix of N-P-K. Soil-less mixes need more frequent fertilizing.
Taking cuttings is the most widely used method to propagate begonias, along with seed propagation.
Stem cuttings: Remove the tip of a stem with three nodes with a knife, eliminate lower leaves, and place the cut end in the rooting mix. Always choose a non-flowering stem.
Leaf cuttings: Rhizomatous begonias are best propagated from leaf cuttings. Remove a young leaf with a leaf stalk, cut into smaller leaves if necessary, and place in a rooting medium so that the leaf blade is not covered.
The rooting medium for stem or leaf cuttings can be peat and sand, or moss, whereas cane-like and shrub-like begonias can also root in water. The addition of rooting hormone is optional.
While you are waiting for a plantlet to emerge, enclose them in a bag or glassy bowl, provide good light, also grow lights.
Seed propagation: Sprinkle the seeds carefully over a sterilized (covered with a foil and baked in the oven at 20 degrees for an hour) and previously moistened mix of sand and peat in a tray or a shallow pot. Use heat mats to provide additional warmth.
Pests and Diseases
Pests and diseases are the most problematic if you have a large greenhouse collection. To prevent these, maintain good hygienic conditions, avoid overhead watering and use sterilized soil and pots.
If you notice any symptoms such as white powder, wax, stunted growth, honeydew, mucus, yellow rings or mottling, even moldy patches on the leaves, stems, or buds, that means that something is wrong with your plant.
It can be mealybugs, mites, nematodes, snails, slugs, weevils, or diseases like mildew or bacterial leaf spot. Immediately quarantine the plant to protect the plant, identify the cause and start the treatment.
