A Florist's Guide to Begonia
Begonias are a diverse group of flowering plants known for their striking foliage and vibrant flowers. With over 1,800 species, they belong to the Begoniaceae family and can be classified into several categories, including fibrous-rooted, tuberous, and rhizomatous varieties. This florist guide will assist you in understanding their care, propagation, and usage in floral arrangements.
Popular Types of Begonias
Begonia Rex: Renowned for its highly decorative leaves, this type features intricate patterns and colours, making it a favourite for indoor decor.
Begonia Semperflorens: Often referred to as the wax begonia, this hardy plant blooms continuously throughout the year, offering charming small flowers in various colours.
Tuberous Begonias: Featuring large, vibrant flowers, these are ideal for summer displays and can brighten up any garden or patio.
Begonia Maculata: Known as the polka dot begonia, it’s distinguished by its striking silver speckles on dark green leaves and occasional red undersides, providing a unique aesthetic.
Care and Maintenance
Light Requirements
Begonias thrive in bright, indirect sunlight. Direct exposure to harsh sunlight can scorch their leaves, while too little light may hinder their flowering. A north or east-facing window often provides the ideal conditions.
Watering
Begonias prefer to dry out slightly between waterings. Water the plant thoroughly when the top inch of the soil feels dry, ensuring that excess water can drain away. Over-watering can lead to root rot, while under-watering may cause wilting.
Humidity and Temperature
These plants enjoy higher humidity levels. To create a suitable environment, consider misting them regularly or placing a tray of water with pebbles underneath the pot. The optimal temperature range for begonias is between 18°C and 24°C.
Soil and Fertilisation
A well-draining potting mix is essential for begonias. Use a mix designed for tropical plants or create your own by combining potting soil with perlite and peat moss. Fertilise during the growing season with a balanced, water-soluble fertiliser every four to six weeks.
Propagation
Begonias can be propagated through leaf cuttings, stem cuttings, or division, depending on the variety.
Leaf and Stem Cuttings: Select a healthy leaf or stem from the parent plant. Place it in water or directly into well-draining soil. Ensure the cutting has adequate light and moisture until roots develop.
Division: For rhizomatous types, gently separate the clumps during potting time, ensuring each division has its roots and foliage.
Usage in Floral Arrangements
Begonias can add a luxurious touch to floral arrangements. Their unique foliage makes them excellent for texture and structure. When combined with other flowers, such as roses or orchids, they create stunning visual contrasts.
Arrangement Tips
Layering: Use begonias as a focal point or backdrop by layering them with taller flowers for added depth.
Colour Coordination: Consider the colour palette; begonias with muted tones can serve as a soft contrast to vibrant blooms.
