A Beginner’s Guide to Begonias: Classification and Diversity<\/h2>\n

Begonia is the fifth largest genus of flowering plants, with over 1,800 species and hybrids. They are known by their bright, full flowers and also their leaves, which vary to showcase patterns, designs, or color (Figure 1). Begonias have a pantropical distribution, occupying the tropical regions of every continent except Australia, and are commonly used in the landscape, although in Florida their heat tolerance makes them more desirable as a potted plant or houseplant. They thrive best in partially shaded areas because they are sensitive to bright light and should be protected from the Florida summers in particular. Begonias grow in USDA Hardiness Zones 3\u201311 and are often used in hanging baskets, flowerpots, and garden beds as well as in the landscape (Gardening Solutions 2019). This EDIS publication is for Florida gardeners and horticulturalists hoping to learn more about the different classifications of begonias, as well as for those interested in learning more about this potential landscape or houseplant.<\/p>\n

Classification and Diversity<\/h2>\n

Begoniaceae falls under the order Cucurbitales, which also includes the valuable family Cucurbitaceae (i.e., pumpkin, zucchini, squash, and other gourds) as well as other small plant families. Begoniaceae is broken down into two genera: Begonia<\/em> and Hillebrandia<\/em>. Horticulturalists and botanists group plants into concise categories, which has proven difficult in begonias due to their ability to easily produce hybrids. Today’s commercially grown begonias are mostly hybrids between wild types collected around the world.<\/p>\n

However, following standards established by the American Begonia Society, begonias can be separated into three main categories: fibrous-rooted, rhizomatous, and tuberous begonias. Due to their diversity and the abundance of hybrids, classifying begonias can be quite the challenge.<\/p>\n

Fibrous-Rooted Begonias<\/h3>\n

Fibrous-rooted begonias can be further divided into wax, or bedding, begonias and include cane-like, shrub, trailing, and thick-stemmed begonias. Though all begonias have fibrous roots, this category is used to describe those that have only<\/em> fibrous roots, as opposed to having rhizomes or tubers also. These plants are most commonly observed as summer bedding plants, adding a splash of color to the landscape.<\/p>\n

Semperflorens Group<\/h4>\n

Also known as “wax begonias,” these are popular bedding plants with erect stems and glossy round leaves, often green or bronze in color (Figure 2). The flowers are small but numerous, appearing in varying shades of red, pink, and white. They are usually produced from seed and grown as annuals, but one can prolong their life with proper care and by moving them indoors in the fall and winter.<\/p>\n

\"Figure<\/p>\n

Cane-like Begonias<\/h4>\n

Cane-like begonias often have erect stems resembling bamboo, which is where they get their name. Cane begonias are known for their highly asymmetric, pointy, wing-shaped leaves, although there are many exceptions (Figure 3). They are sometimes referred to as “angel wing begonias” and are known for their foliage, which is often shiny, hairy, colorful, or dotted. Flowers are typically small, appearing in red, pink, and white, similar to wax begonias.<\/p>\n

\"Figure<\/p>\n

Shrub Begonias<\/h4>\n

Plants that fall into this grouping are known for producing many shoots that come up from the soil to make a full plant. Shrub begonias are ideal for use as bedding plants (Figure 4). Though not as popular as other types of begonia in the landscape, shrub begonias are very easy to grow and tend to have unique leaves accompanied by mostly white flowers, although pink and red have been cultivated recently. This group has the largest distribution of growth size, ranging anywhere from 1 to 12 feet across.<\/p>\n

\"Figure<\/p>\n

Trailing-Scandent<\/h4>\n

To impress your friends with big, beautiful hanging-basket displays, consider trailing begonias (Figure 5). In their native habitat, these plants can be found climbing trees or filling the gaps in ground cover. They are perfect for placement on top of outdoor walls so that they may cascade downward with a beautiful array of white or pink flowers.<\/p>\n

\"Figure<\/p>\n

Thick-Stemmed<\/h4>\n

This grouping is difficult to grow well and even harder to find. They usually have one or two upright stems but do not branch naturally (Figure 6). They enjoy plenty of light, but midday sunlight can burn the leaves, making this one of the pickiest groupings of begonia. The thick stem is the showiest aspect of these plants because they tend to lose their lower leaves as they grow, leaving the view of the stems unobstructed.<\/p>\n

\"Figure<\/p>\n

Rhizomatous Begonias<\/h3>\n

As the name suggests, these begonias have a rhizome, which is a thickened underground stem that typically grows horizontally, sprouting new sections along the rhizome. This is considered the largest grouping of begonias, with hundreds of species and thousands of cultivars. The majority are fairly compact with round or star-shaped leaves. Due to their short day requirement for flowering, most bloom in the winter with pink or white flowers. They are mainly grown for their colorful foliage. Rhizomatous begonias were originally thought of as indoor plants, but they have recently been used as excellent plants for shady flowerbeds.<\/p>\n

Rex Begonias<\/h4>\n

A personal favorite of many plant collectors, rex begonias include hybrids produced from B. rex<\/em> and other begonias. All resulting hybrids are grouped under B.<\/em> \u00d7 rex-cultorum<\/em>. Of all the groupings, rex begonias have the most vibrant foliage, coming in all shades of green, red, purple, pink, silver, and brown, and their leaves often have a metallic or iridescent glow (Figures 7 and 8). Foliage comes in many shapes, but most have ear-shaped, star-shaped, or sought-after spiral leaves. Little attention is paid to the pink or white flowers.<\/p>\n

\"Figure<\/p>\n

\"Figure<\/p>\n

Tuberous Begonias<\/h3>\n

Tubers are similar to rhizomes, but they have some key differences. Tubers are modified stems with starchy interiors, with both roots and shoots growing from the same buds, similar to a potato. Hybrid tuberous begonias include the classic large-flowered begonias used extensively by gardeners. The flowers come in colors ranging from the typical white, red, and pink to the much less common yellow, purple, orange, and more. Flowers are extremely large and are often found in pairs. This grouping includes the hugely popular ‘Nonstop\u00ae’ series of begonia, which is grown worldwide (Figure 9).<\/p>\n

\"Figure<\/p>\n

Bolivian Begonias<\/h4>\n

Originating from B. boliviensis<\/em> and its hybrids, these begonias have recently made a comeback in the market after disappearing for decades (Figure 10). They are known for their enormous tubers and long narrow leaves. Originally a cliff-dwelling species with a trailing habit, the flowers come in shades of orange, red, yellow, pink, and white with long pointed tepals that attract the attention of hummingbirds.<\/p>\n

\"Figure<\/p>\n

Hiemalis Begonias<\/h4>\n

The plants that fall into this group originated from the rare winter species B. socotrana.<\/em> These plants bloom naturally in the winter, yet hybrids that bloom all year long have been produced by subjecting them to artificially short days. The flowers are smaller than other tuberous begonias but are larger than other types of begonias (Figure 11). They come in all colors except blue and usually appear in doubles. They are notoriously difficult to recuperate after a flowering cycle, so most growers simply start new plants every year.<\/p>\n

\"Figure<\/p>\n

Lorraine Begonias<\/h4>\n

Also known as Christmas begonia (B.<\/em> \u00d7 cheimantha<\/em>), this is a cross between B. socotrana<\/em> and B. dregei<\/em>. As with Hiemalis begonias, it is difficult to maintain from year to year (Figure 12). Known for its abundant pink or white flowers, it was aptly named Christmas begonia due to its early-winter blooming period. The first cultivar was named ‘Gloire de Lorraine’, which is where it gets its common name.<\/p>\n

\"Figure<\/p>\n

Semituberous Begonias<\/h4>\n

This group of begonias resembles small trees, and for this reason, they are commonly grown as bonsai trees even though their stems are not actually woody. They commonly have a swollen stem base (caudex) and small leaves with small, white flowers. The most common species is B. dregei<\/em>, and all varieties stem from this one species (Figure 13). They should be treated as succulents.<\/p>\n

Begonia – Collection – 3 Varieties<\/h2>\n

Begonias are one of the most stunning if not THE most stunning additions to the shade garden. Begonias love growing and blooming in the shade unlike most other flowering plants. Expect to enjoy blooms summer to frost! Begonias come in many different types. The most common cultivated groupings are cane-stemmed, rex-cultorum, rhizomatous, semperflorens, shrublike, tuberous and winter-flowering. We primarily focus on tuberous begonias, which is what the following planting information is in reference to. Tuberous begonias are available in upright growing habits (grown in beds, borders, planters) as well as pendulous, cascading habits (grown in hanging baskets, window boxes and containers). There are endless options in bloom size and color!<\/p>\n

    Growing Instructions<\/h3>\n

    Jump start begonias indoors in pots or flats in January. Fill the container with damp peat moss evenly leveled to the top. Press tubers into the damp peat but do not cover. Begonia tubers will rot if they become wet and cold. Keep pots in a warm place day and night (60-65\u00baF) and keep the peat moss moist. In the spring after all danger of frost has passed and the plants are around 3″ high they can be transplanted outdoors into a shady area of the garden. The ideal soil is rich, porous and drains well but still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments like peat moss or ground bark. Spread a 3-4 inch layer of soil amendment if needed, add fertilizer and incorporate into the soil to a depth of 10 inches. Plant 1-2″ deep and 6-12″ apart (depending on type). When planting a large quantity of tubers in one bed, excavate the entire area to the recommended depth, work fertilizer into the bottom of the trench, set out tubers and then cover tubers all at once.Water thoroughly at planting. While actively growing, water frequently and thoroughly so that water will reach the roots. Mulch to keep the soil cool and to prevent the soil from drying out. Begonias will bloom in approximately six weeks and will continue to bloom until frost. For container planting, plant 2-5 tubers per 12″ pot. After blooming, remove the foliage, dry and clean the tubers and store in dry peat moss or vermiculite at approximately 40\u00baF.<\/p>\n

    Care Tip<\/h3>\n

    Tuberous begonias require winter dormancy. Dig up tubers in the fall after the tops appear to have died back and the soil is completely dry. Being extra careful, clean the soil from the tubers and store in a warm, dry location over the winter. Start the planting process again for spring!<\/p>\n","protected":false},"excerpt":{"rendered":"
