All About Begonias: A Guide to Classification, Propagation, and Care
Begonias are a diverse group of plants with over 1,000 species. They come in all shapes and sizes, with different types of flowers, leaves, and growth habits. This makes them a popular choice for gardeners of all levels.
Classification of Begonias
Begonias are classified into six subclasses based on their flowers, propagation methods, and leaves. Each subclass has its own unique characteristics.
- Tuberous begonias: These begonias are grown for their showy flowers, which can be double or single petaled, frilled, and a variety of colors. Their leaves are oval and green, and they grow from swollen, soft stems.
- Cane-stemmed begonias: These begonias are grown mostly for their leaves, which are heart-shaped and gray-green. The plants are frost tender and can reach up to 10 feet in height.
- Rex-cultorum begonias: These begonias are also grown for their foliage, which is very striking. The leaves can be bright red, green, pink, silver, gray, and purple in vibrant combinations and patterns.
- Rhizomatous begonias: These begonias have hairy and slightly warty leaves that can come in several shapes. The multi-pointed leaves are called star begonias.
- Semperflorens begonias: These begonias are also called annual or wax begonias due to their fleshy, waxy leaves. The plants grow in a bushy form and are prized for their constant and prolific blooming.
- Shrub-like begonias: These begonias are compact and have tight clusters of leaves. The leaves are often dark green but may have colored spots.
Propagation of Begonias
Begonias can be propagated by a variety of methods, including:
- Stem cuttings: Stem cuttings can be taken from healthy begonias and rooted in water or soil.
- Leaf cuttings: Leaf cuttings can be taken from begonias with large, healthy leaves. The leaves are cut into sections and rooted in soil.
- Rhizomes: Rhizomes are fleshy, underground stems that can be divided and planted to create new begonias.
- Tubers: Tubers are swollen, underground stems that can be planted to create new begonias.
Care of Begonias
Begonias are relatively easy to care for, but they do have some specific requirements.
- Light: Begonias prefer bright, indirect light. Avoid placing them in direct sunlight, as this can scorch the leaves.
- Water: Begonias need to be watered regularly, but avoid overwatering. Allow the soil to dry out slightly between waterings.
- Fertilizer: Begonias should be fertilized monthly during the growing season. Use a balanced fertilizer that is diluted to half strength.
- Temperature: Begonias prefer warm temperatures between 65 and 75 degrees Fahrenheit. Avoid exposing them to cold temperatures, as this can damage the leaves.
- Humidity: Begonias prefer high humidity. You can increase the humidity around your begonias by placing them on a tray of pebbles filled with water.
Uses of Begonias
Begonias are versatile plants that can be used in a variety of ways in the garden. They can be grown in containers, hanging baskets, or in the ground. They are also popular for use in flower arrangements.
Conclusion
Begonias are a beautiful and diverse group of plants that are easy to care for and can add a touch of elegance to any garden. With proper care, begonias can thrive for many years and provide you with years of enjoyment.
