Do you know that begonias have been in many Top 10 Favorite Plant lists for many years? And for good reason!
Although some people might think begonias are fusty old plants that Grandmother grew, their gorgeous foliage, huge ever-blooming flowers, and easy care make them popular plants.
We predict that when succulents are “out,” begonias will be the new stars.
The Begonia family – begoniaceae – consists of 1500 plant species native to the tropic and subtropic areas of both the eastern and western hemispheres.
Begonias are hardy perennials in horticultural zones 10 and 11, where some types can reach heights of 10 feet! In colder zones, begonias are grown as summer annuals. Begonias are also grown as houseplants for their beautiful leaf patterns.
How many types of begonias are there?
Begonia species have been cultivated for centuries. Today there are over 10,000 hybrids.
Obviously, we can’t discuss all the many types here, but let’s look at some of the most outstanding varieties and ways to use them in your garden and your home. You’re sure to find one that’s perfect for you. (1)
Horticulturists divide begonias into groups based on their roots: fibrous, rhizomatous, and tuberous.
Fibrous roots branch out in all directions and are often threadlike.
Rhizomatous roots send out runners just under or along the soil.
Tuberous roots are thick and fleshy – potatoes are tubers.
This information comes in handy when identifying a type of begonia and determining a begonia’s best use and its proper care. Begonia root structures can also help determine the appropriate propagation method for your plant.
How do I tell what kind of begonia I have?
With thousands of varieties, begonia plant identification can be difficult, but it’s not impossible.
First, look at the roots to determine if you have a tuberous, fibrous, or rhizomatous begonia.
Consider the growth habit of your begonia. Is it upright, mounding, or trailing?
Next, look at the stems. Jointed stems indicate you have a cane begonia; an absence of branching indicates a shrub type begonia.
The leaves are the next identifier. If your begonia has beautifully patterned leaves, it is most likely a rex begonia. An obliquely shaped leaf that looks like a wing indicates an angel wing or dragon wing begonia. Green or bronze oval leaves let you know you have a wax begonia.
Finally, look at the flowers. An absence of flowers, or small insignificant flowers, tell you it’s probably a rex or shrub-like begonia. Lots of big, beautiful blooms are hallmarks of tuberous and hiemalis begonias.
Read (and look at the pictures) of the most popular begonia types below, which can help you identify your begonia. The American Begonia Society’s website also has many articles describing begonia types, which can help you figure out which one you have. Gardening catalogs or an online image search can also help you determine the type of begonia you have.
Fibrous Begonias (Begonia x semperflorens-cultorum)
Fibrous begonias are great for growing in gardens. They can take a little more sun exposure than other types, and they aren’t overly picky about water as long as they are kept moderately moist.
They are more adaptable to a variety of growing conditions than some of the other begonia types, and that’s a big part of their appeal.
Common Name: Wax Begonias
Scientific Name: Begonia x semperflorens-cultorum
Size: Very uniform plants that are 6 to 8 inches tall.
Flower Colors: Red, pink, rose pink, and white.
Characteristics: Wax begonias have waxy, glossy, oval leaves that are green or bronze. Their flowers are produced in a cluster and bloom continuously from first to last frost. The Cocktail and Super Olympia varieties have been garden favorites for decades.
Design ideas: Wax begonias make excellent bedding plants. Their uniform habit and continuous flowering make them strong performers in garden beds or containers. Plant them with black mondo grass, carex, caladiums, or ferns. Or tuck them in around shade-loving perennials like hosta and heuchera.
Angel Wing Begonias
Common Name: Angel Wing Begonias
Scientific Name: Begonia ‘Angel Wings’
Size: About 10 to 20 inches tall, but some types can be taller.
Flower Colors: red, pink, white, bicolor.

Rhizomatous Begonias (Begonia x hybrida)
Rhizomatous begonias are grown for their beautifully patterned leaves. Sometimes referred to as foliage begonias, their leaves are patterned with multicolor swirls and splashes. The flowers are often insignificant.
Most commonly grown as houseplants, rhizomatous types can also make a statement in a shady garden area or as part of a container arrangement. This type of begonia requires less water and fertilizer than other types and is often slow-growing.
Common Name: Shrub-like Begonias
Scientific Name: Begonia metallica, begonia luxurians, and others
Size: Varies – some varieties are miniatures, others are measured in feet!
Flower colors: The flowers are insignificant; this plant is grown for its leaves.
Characteristics: Shrub-type begonias grow like any typical, with many stems growing up from the soil. The stems do not branch as other begonia types do.
Design ideas: Use the larger types as backdrops to a shady foliage bed. They will work well with impatiens, hosta, and ferns. The smaller types work well in pots and planters either as the star or in a supporting role.

Design ideas: This is the gorgeous houseplant your grandmother has on her windowsill! Rex begonias are stunning in the indoor garden or a terrarium, but some can also be used as a statement plant outdoors.
Tuberous Begonias (Begonia x tuberhybrida)
These types of begonias are grown for their beautiful flowers and are big performers in semi-shady gardens. A tuberous begonia likes a little more shade, a little less heat, and a little less water than other begonias.
A tuberous begonia can be overwintered – simply lift the tubers, shake off the soil, and store in a cool, dry place until planting time in spring.
Common Name: Non-Stop begonias
Scientific Name: Begonia x tuberhybrida Non-Stop
Size: 8 to 10 inches high
Flower Colors: red, orange, pink, yellow, rose, white, white with rose pink.

Scientific Name: Begonia x hiemalis Size: 8 to 12 inches high.
Flower colors: Double flowered in shades of orange, red, yellow, peach, pinks, and bicolors.
Characteristics: Hiemalis begonias are a cross between wax and tuberous begonias. Bred to bloom in winter, plants in this group are often sold as houseplants, but they have their place in the garden as well.
Design ideas: These types of begonia would be perfect for growing as winter annuals in areas with mild winters since they don’t like temperatures about 80°F. Their mounding and trailing growth habits lend themselves to use in pots and hanging baskets.
Care of Your Begonias
Some people might think that begonias are hard to grow, but if you meet their water, sun, and fertilizer conditions, you will find that begonias are pretty easy going.
Outdoors, begonias prefer a shady location out of the midday sun. They will grow best with morning sun and afternoon shade. They like well-draining soil; in containers and hanging baskets, use a soilless potting mix.
Indoors, begonias like bright, indirect light. A north or east-facing window offers the best sun exposure.
Indoors and out, water when the top of the soil is dry. Begonias like moist soil, but they don’t like to be constantly wet.
Take care not to get water on the begonia leaves, especially with indoor plants. This can cause the foliage to rot.
Fertilize every other week with a balanced liquid fertilizer. Houseplants stop growing in late autumn, so don’t fertilize your indoor begonias in winter.
Do Begonias Come Back Every Year?
Only in zones 10 and 11.
Begonias are tropical plants and cannot survive temperatures below freezing. In colder climates (zones 3 to 9) they are grown as annuals.
Tuberous begonias can be lifted and stored in a dry cool place for planting the next spring. Be careful not to nick or damage the tubers when you lift them as that can cause rot.
Which Begonias Take Full Sun?
Wax begonias, especially the bronze leaf varieties, can take full sun.
Angel wings and landscape begonias like Whopper are also tolerant of full sun conditions. However, they will perform their best if given an eastern exposure and a break from the hot sun in the afternoon.
Begonias in full sun will need more water than their shade dwelling counterparts.
