Are begonias corms or tubers? If you’re a gardening enthusiast, chances are you’ve pondered this question at some point. It can be a little confusing trying to distinguish between the two, especially if you’re not familiar with the structural differences. After all, both corms and tubers are specialized underground plant organs that serve as storage units for nutrients and energy. However, there are some key differences between the two that can help you identify which category begonias fall into.
For starters, let’s define what corms and tubers are. A corm is a short, swollen, underground stem that has a protective outer layer. It’s a tightly packed ball of stem tissue that contains stored food for the plant. In contrast, a tuber is an enlarged, fleshy root that also serves as a storage organ. It has a relatively thin, papery skin and is made up of various types of modified stems and shoots. With that said, are begonias corms or tubers? The answer is somewhat complex and requires a closer examination of the plant’s structure.
Begonias are herbaceous perennial plants that belong to the family Begoniaceae. They come in various sizes, shapes, and colors and are widely grown as ornamental plants in gardens and homes. The underground storage organ of the begonia is typically referred to as a corm, although some species may have more tuber-like structures. This makes the question of whether begonias are corms or tubers not so straightforward. Ultimately, the best way to determine which category a particular begonia falls into is to closely examine its root system and overall structure.
The Anatomy of Begonias Corms and Tubers
Begonias are an interesting genus of plants, with over 1,800 species. They come in a wide range of shapes, sizes, colors, and textures. Begonias are classified into four groups- tuberous, rhizomatous, cane-like, and semperflorens. In this article, we’ll focus on tuberous begonias and the anatomy of their corms and tubers.
- A corm is a large swollen underground stem that stores nutrients for the plant. Corms grow along the stem and usually, but not always, produce new shoots at the top of the corm. Tuberous begonias, unlike most corms, grow on the surface of the soil which makes them more susceptible to being dug up.
- A tuber is also an underground stem, but it functions differently from a corm. Rather than storing nutrients for the plant, a tuber stores food as starch, similar to a potato. Tubers are elongated, and they have eyes from which new leaves and stems develop.
- Begonias store starch in their tubers, corms, and even in their leaves. This starch is a vital energy source that helps the plant survive underground during dry and cold seasons.
Tuberous begonias typically grow from a single tuber, which produces stems that can reach up to 30cm in length. The plant’s leaves grow oppositely along the stem, and the flowers appear from the axils of the leaves. The tubers of a tuberous begonia are shaped like a flattened sphere and are usually less than 2 inches wide. The roots grow from the bottom of the tuber and can extend several inches into the soil, providing a firm anchor for the plant.
Below is the table that summarizes the anatomy of tuberous begonias, including the characteristics of their corms and tubers.
| Plant Part | Description |
|---|---|
| Corm | Large, swollen underground stem that stores nutrients for the plant. It grows along the stem and usually produces new shoots at the top of the corm. |
| Tuber | Underground stem that stores food as starch. They are elongated and have eyes from which new leaves and stems grow. |
| Starch | A vital energy source that helps the plant survive underground during dry and cold seasons. Begonias store starch in their tubers, corms, and even in their leaves. |
| Leaves | Grow oppositely along the stem. They are green with red, white, or silver patterns or edging. |
| Flowers | Appear from the axils of the leaves. They come in a wide range of colors, including white, pink, red, orange, and yellow. |
Now that you know a bit more about the anatomy of tuberous begonias, you will be able to understand how they function and grow. Whether you are an experienced gardener or just starting, this knowledge is beneficial for tending to your plants and ensuring that they will thrive. Happy gardening!
Differences between Corms and Tubers
While both corms and tubers are used for vegetative propagation, they have distinct differences that set them apart from each other.
- Structure: Corms are generally solid structures that do not contain any internal rings or scales, whereas tubers have internal rings or scales and are typically irregularly shaped.
- Growth: Corms produce new growth from the top of the corm, while tubers produce new growth from the eyes or nodes along the sides of the tuber.
- Storage: Corms store most of their nutrients in the center of the structure, while tubers store nutrients in their flesh.
It is important to differentiate between corms and tubers when planting, as they have different requirements for planting depth and planting orientation. When planting corms, they should be planted with the top of the corm just below the soil surface. On the other hand, tubers should be planted with the nodes facing upwards and covered with soil to a depth of two to four times the width of the tuber.
Here is a table that highlights the key differences between corms and tubers:
| Corms | Tubers | |
|---|---|---|
| Structure | Solid with no internal rings or scales | Irregularly shaped with internal rings or scales |
| Growth | New growth from top of corm | New growth from nodes or eyes along sides of tuber |
| Storage | Stores most nutrients in center of structure | Stores nutrients in flesh |
By understanding the differences between corms and tubers, gardeners and growers can choose which propagation method is best for their specific plants and ensure successful growth and development.
Common Begonias Species and Their Corms or Tubers
One of the most popular flowering plants, the Begonias, is known for its beautiful, brightly colored blooms that come in a variety of shapes and sizes. But for those who want to grow them, it’s important to know that begonias can either grow from corms or tubers. So, what are corms and tubers in Begonias?
Corms are underground swollen stems that store food and nutrients for the plant. They are small, round, and similar in shape to a bulb. Begonias that grow from corms include the Rex Begonia, also known as the Painted-Leaf Begonia.
Tubers, on the other hand, are fleshy, underground parts of the stem that store food and water for the plant. They are usually larger and more irregular in shape than corms. Begonias that grow from tubers include the Tuberous Begonia, a popular choice for both gardeners and florists.
Common Begonias Species and Their Corms or Tubers
- Rex Begonia (corm)

Propagating Begonias from Corms or Tubers
Begonias are beautiful and popular flowering plants that have unique characteristics. They grow from either corms or tubers, which are compressed underground stems that act as energy storage for the plants’ growth cycle. Here’s a guide to propagating Begonias from corms or tubers.
- Understand the difference between corms and tubers: Before propagating Begonias, it is crucial to understand the difference between corms and tubers. Corms are solid, swollen storage stems that have a flat bottom, while tubers are round and have small buds or “eyes” on them.
- Start with healthy corms or tubers: Healthy corms or tubers are the key to getting a successful yield. Look for plump and firm corms or tubers that have no visible signs of disease or damage.
- Propagate during the dormant season: The best time to propagate Begonias from corms or tubers is during their dormant season, which is usually in early spring. This is the time when the plants remain dormant and have stored the most energy.
If you’re propagating Begonias from corms, you can follow these steps:
- Plant the corms in well-draining soil that is rich in nutrients. Keep them in a warm and humid place, but not in direct sunlight.
- Water the corms regularly to keep the soil moist, but not waterlogged.
- After a few weeks, small shoots will begin to appear from the corms. Continue to care for the plants until they reach maturity.
If you’re propagating Begonias from tubers, follow these steps:
- Plant the tubers with the buds facing upward in well-draining soil that is rich in nutrients. Keep them in a warm and humid place, but not in direct sunlight.
- Water the tubers regularly to keep the soil moist, but not waterlogged.
- After a few weeks, small shoots will begin to appear from the tubers. Continue to care for the plants until they reach maturity.
Here’s a table summarizing the differences between propagating Begonias from corms and tubers:
| Propagation Method | Advantages | Disadvantages |
|---|---|---|
| Corms | Produce more offsets, easier to separate, and faster maturation time. | Require regular watering and can be more sensitive to over-watering. |
| Tubers | Produce more roots and have more energy stored for growth. | More challenging to separate, longer maturation time, and more susceptible to rotting in soil. |
In summary, propagating Begonias from corms and tubers is easy and rewarding. With these tips, you can grow beautiful begonias in your garden or home. Remember to use healthy corms or tubers, propagate during the dormant season, and provide adequate care to ensure a successful yield.
How to Store Corms and Tubers of Begonias
Begonias are beautiful flowers that come in a variety of colors and sizes. They are grown from two types of underground storage organs: corms and tubers. Corms are compressed, fat stems that store nutrients, while tubers are modified roots that store nutrients. Regardless of their type, storing corms and tubers properly is crucial to ensure healthy growth and flowering in the future.
- Timing: First, it’s important to know when to store the corms and tubers. Once the plant starts to die back and the leaves turn yellow, it’s time to dig them up and store them for the winter.
- Cleaning: After digging up the corms and tubers, gently remove any soil and debris attached to them. Be careful not to damage any of the growth buds or scars that could potentially become new shoots.
- Drying: Allow the corms and tubers to air dry for a few days in a cool, dry, and shaded area. This step will prevent the risk of fungal and bacterial infections during storage.
Once the corms and tubers are dry, they can be stored in several ways:
- Peat Moss: Fill a container with peat moss and place the corms and tubers on top, making sure there’s enough space between them. Cover with more peat moss and store in a cool, dark place with a temperature between 45-50°F (7-10°C). Check the container occasionally and mist the peat moss if it feels dry.
- Sawdust: Similar to peat moss, cover the corms and tubers with sawdust in a container. Keep in a cool, dark place with a temperature between 45-50°F (7-10°C), and check occasionally for any signs of mold or decay.
- Plastic Bags: Place the corms and tubers in a paper bag or old nylon stocking and tie it shut. Store the bags in a cool, dark place with a temperature between 45-50°F (7-10°C).
It’s important to note that storing corms and tubers at higher temperatures could lead to mold and rot. Additionally, do not refrigerate or freeze the storage containers, as this will cause the corms and tubers to dry out and die.
| Corms vs Tubers: | Corms | Tubers |
|---|---|---|
| Shape: | Compressed, fat stems | Modified roots |
| Storage Organ: | Stem | Root |
| Storage Location: | Just under the soil surface | Deeper in the soil |
| Propagation: | Can be divided into smaller corms | Grows new tubers on the main one |
Corms and tubers of begonias make storing and propagating these beautiful flowers easier than other types of bulbs. With proper care and attention, they can be enjoyed year after year.
The Importance of Proper Care for Begonias Corms and Tubers
Begonias are a beautiful and popular flowering plant that can be grown from both corms and tubers. They come in a variety of colors and can add a touch of elegance to any garden or indoor space. However, it’s important to take proper care of these corms and tubers for optimal growth and longevity.
- Choosing the right soil: Begonias prefer well-draining soil that is rich in organic matter. A mixture of peat moss, perlite, and vermiculite is optimal for these plants. Avoid heavy clay soils that tend to hold onto moisture.
- Providing proper water: Overwatering can lead to root rot, while underwatering can cause the corms or tubers to dry out. Water the plants when the top inch of soil feels dry, and avoid getting water on the foliage, as this can lead to fungal diseases.
- Ensuring adequate light: Begonias prefer bright, indirect light. Too much direct sunlight can scorch the foliage, while too little light can cause weak growth and poor blooming.
In addition to these general care tips, it’s important to take specific precautions when it comes to caring for corms and tubers.
Caring for Corms: Corms are swollen underground stems that store nutrients for the plant. It’s important to allow the corms to fully dry out before storing for the winter. This helps prevent rot and ensures that the plant has enough stored energy to make it through the dormant season.
Caring for Tubers: Tubers are similar to corms but are elongated and have a rough, papery skin. When the foliage dies back in the fall, it’s important to cut it off and allow the tubers to dry out for a couple of weeks before storing. Store the tubers in a cool, dry place, and avoid exposing them to temperatures below 40°F or above 60°F.
| Corms | Tubers |
|---|---|
| Swollen underground stems | Elongated with papery skin |
| Store nutrients for the plant | Store nutrients for the plant |
| Allow to fully dry out before storing for the winter | Cut off foliage and allow to dry out for a couple of weeks before storing |
Proper care for begonias corms and tubers can ensure that these plants thrive and produce beautiful blooms year after year. By following these care tips, you’ll be able to enjoy the beauty of these plants for seasons to come.
