Types of Wax Begonias

Wax begonias are popular plants known for their versatility in garden beds, containers, and indoor settings. They are divided into various types, each having its unique characteristics, care requirements, and appearance. In this section, we’ll discuss three main types of wax begonias: Fibrous-Rooted Begonias, Tuberous Begonias, and Rex Begonias.

Fibrous-Root Begonias

Fibrous Root Begonias

Fibrous-root begonias are a type of begonia plant that has a fibrous root system. These plants are known for their delicate, brightly colored flowers and their ability to thrive in a variety of growing conditions. The fibrous roots of begonias are thin and thread-like, and they spread out in all directions to absorb water and nutrients from the soil. Fibrous-root begonias are popular as houseplants and garden plants because they are easy to care for and can be grown in a wide range of climates. They come in a variety of colors, including pink, red, orange, and white, and they bloom in the spring and summer months. 

Tuberous Begonias

Tuberous Begonias

Tuberous begonias are a type of begonia plant that grows from a tuber, which is a swollen underground stem that stores nutrients and water. These plants are known for their large, showy flowers that come in a range of colors, including red, pink, orange, yellow, and white. Tuberous begonias are popular as garden plants and as houseplants because of their striking appearance and their ability to bloom for long periods of time. They prefer cool, moist environments and need well-draining soil to prevent their tubers from rotting. Tuberous begonias are typically grown from dormant tubers, which are planted in the spring and bloom in the summer and fall.

Rex Begonia

Rex Begonias

Rex begonia is a type of begonia plant known for its striking foliage. The leaves of rex begonias are large, asymmetrical, and come in a variety of colors and patterns, including silver, green, purple, and pink. The leaves are often textured and have a velvety or hairy appearance. Rex begonias are popular as houseplants because of their unique appearance and relatively low maintenance requirements. They prefer bright, indirect light and well-draining soil. Rex begonias are sensitive to overwatering and should be allowed to dry out slightly between waterings. They are typically propagated by stem or leaf cuttings, and can be grown year-round in warm, humid environments.

Characteristics of Wax Begonias

Wax begonias, belonging to the Begonia Semperflorens-Cultorum group, are popular plants known for their versatility in both sunlight exposure and ease of care. This section will focus on the key characteristics of wax begonias, including their leaves and stems, as well as their flowers and colors.

Leaves and Stems

The leaves of wax begonias are waxy and come in various shades, such as green, bronze, or reddish-brown. These glossy round leaves grow in compact, bushy mounds that contribute to the plant’s low-growing and spreading nature. Wax begonias have erect stems that further support their overall appearance as dense and bushy plants.

Flowers and Colors

Wax begonias are admired for their beautiful and numerous flowers that appear in different shades of red, pink, and white. Although the flowers are small in size, their vibrant and rich colors make them stand out in any garden. Wax begonias bloom throughout summer and fall, and when grown indoors as houseplants, some varieties can produce flowers all year long.

These plants’ ability to grow in various light conditions, combined with their low maintenance requirements, make wax begonias an excellent choice for adding color and visual interest to gardens and indoor spaces alike.

Growing and Caring for Wax Begonias

Wax begonias are versatile and low-maintenance plants that thrive in a variety of conditions. In this section, we will discuss the key aspects of growing and caring for wax begonias, so you can enjoy their colorful blooms all season long.

Light Requirements

Wax begonias can grow in both full sunlight and shade, although they may need more frequent watering in full sun to prevent them from drying out. Indoors, it’s essential to provide at least 8 to 10 hours of artificial light per day, using a mix of warm and cool colors to encourage healthy foliage and flower production.


When it comes to watering wax begonias, keeping the soil consistently moist but not soggy is important. Overwatering can lead to root rot, so it’s best to let the top inch of soil dry out between waterings. During dry weather or when growing in full sun, you may need to water more frequently to prevent wilting.

Soil and Fertilizer

Wax begonias prefer well-draining soil with a slightly acidic pH. You can use a standard potting mix, adding in some peat moss, compost, or perlite to improve drainage. Fertilize your begonias every 4 to 6 weeks during the growing season with a balanced, water-soluble fertilizer to encourage healthy growth and blooms.

Pruning and Maintenance

Regular pruning and maintenance help to maintain a compact, bushy shape in wax begonias, which can become leggy if left unattended. Pinch back the growing tips regularly, and remove any dead or yellowing leaves to encourage new growth. Additionally, deadheading spent flowers will promote continued blooming.

Propagating Wax Begonias

If you wish to propagate your wax begonias, take a stem cutting in the spring, 3 to 4 inches in length, and place it about 2 inches deep into the soil. Keep the soil moist and the air around the cutting humid while it forms roots.

Following these simple care tips will help you grow healthy and attractive wax begonias in your garden or home.

Common Pests and Diseases

Wax begonias are generally low-maintenance plants, but they can still be susceptible to certain pests and diseases. By being aware of these issues, you can take preventative measures and ensure the health of your begonias.


  • Spider Mites: These tiny pests can cause deformity and discoloration of the leaves. Insecticidal soap can be effective in treating these pests.
  • Aphids, Whiteflies, and Mealybugs: These insects can also damage the leaves of your begonia plants. Using insecticidal soap or neem oil can help keep them under control.
  • Scale: Scales can cause damage to the stems and leaves of wax begonias. They can be removed by hand or treated with a horticultural oil spray.
  • Slugs and Snails: These creatures enjoy munching on begonia leaves. They can be easily removed by hand or deterred with diatomaceous earth or organic slug bait.


  • Root Rot: This condition can occur as a result of overwatering. Avoid excessive moisture by allowing the soil to dry out between waterings, but don’t let it become bone dry. Proper care of your begonias can help prevent this issue.
  • Stem Rot and Powdery Mildew: These fungal diseases can also result from overwatering. Good air circulation and avoiding evening watering can help reduce their occurrence.
  • Leaf Spot: Caused by a variety of pathogens, leaf spot appears as discolored or necrotic areas on the leaves. To help prevent this disease, keep the foliage dry and ensure proper spacing between plants for better air circulation.
  • Bacterial Leaf Spot and Blight: This disease presents as water-soaked areas surrounded by yellow halos on the leaves. Ensure your begonia plants are free of this disease when purchasing, discard infected plants, and remove infected leaves to prevent its spread.

Taking the necessary steps to prevent and address these common pests and diseases will keep your wax begonias healthy and thriving.

Propagating Wax Begonias

Propagating wax begonias is a simple and rewarding process. They are relatively easy to propagate from stem cuttings, and with the right care, you can have new plants in a short time. This section will guide you through the steps.

Taking Cuttings

To begin, select a healthy wax begonia with a few nodes on its stems. With a clean pair of snips, cut a 3-4 inch sprig from the plant in the spring. Make sure the cutting has a few nodes on it. Remove the bottom leaves about two inches from the bottom, leaving only the top leaves. Optionally, you can dip the cut end into a rooting hormone to encourage faster root growth.

Preparing the Soil and Planting

Choose a growing tray or a pot with a drain hole and fill it with potting soil. Gently insert the cutting into the soil at least 2 inches deep, ensuring the bottom leaves are above the soil line. Keep the soil moist but not overly saturated, as too much water can cause the cutting to rot. Wax begonias prefer damp soil for optimal growth.

Caring for the Cuttings

Place the potted cutting in a warm and well-lit spot away from direct sunlight. The ideal temperature for wax begonias is between 65-75°F (18-24°C). Keep the humidity high during this stage, as it encourages root formation. You can achieve this by covering the pot with a plastic bag or placing it in a humid environment.

Checking for Root Development

In about 4-6 weeks, your wax begonia cutting should start to develop roots. Gently tug on the cutting to feel for resistance, which indicates root growth. Once roots have formed, you can reduce the humidity and transplant the new plant into a larger container or its final location in the garden.

In conclusion, propagating wax begonias is a straightforward process that can be accomplished with a few simple steps. By choosing healthy cuttings, providing the right soil and humidity conditions, and monitoring root growth, you can have thriving new plants for your garden or home.

Uses and Benefits

Wax begonias, scientifically known as Begonia semperflorens, are popular additions to gardens and landscapes due to their attractive features and versatility. These beautiful plants offer a range of uses and benefits that make them a favorite among both amateur and professional gardeners.

One of the primary uses of wax begonias is for their aesthetic appeal. They showcase clusters of small, dainty flowers in shades of red, pink, or white, accompanied by round or ovate leaves with a waxy texture. Their compact growth habit, reaching a height of 6 to 12 inches, makes them suitable for use as borders, edgings, or in containers.

Another notable benefit of wax begonias is their adaptability to different light conditions. They can thrive in both full sun and partial shade, making them ideal for various garden settings.
