Indoor begonias tend to fall into 4 types of tuberous, fibrous, cane-stemmed and rhizomatous. If you are looking for easier and more long-lived houseplants then fibrous and rhizomatous are the ones to go for. Tuberous, on the other hand, tend to do better outdoors, but they can be grown in a home environment but they tend not to do well. In fact, if you do not grow in exact conditions of high humidity and better light, it will simply fail.

Fibrous root begonias are tender evergreen with erect, shrubby stems. Most are grown for their colourful leaves that are often marked silver and come in elaborate shapes. B. scharfii (Elephant Ear Begonia) and B. semperflorens-cultorum (Wax Begonia) fall into this group.

Cane stemmed begonias tend to be woody, fibrous evergreen perennials that are also tender, The stems are bamboo-like, erect, smooth and have swollen node. The plants that fall in this group include B. stipulacea and B. maculata (Polka Dott Begonia) that are grown for their beautiful leaves and long-lasting flowers.

One of the main groups for indoor plants is rhizomatous begonias and are often grown for their bright colourful leaves, B. masoniana  (Iron Cross Begonia) and B. rex hybrids (Rex Begonia) are found in this group. It is a tender evergreen perennial that has a creeping rootstock.

Tuberous begonias (Begonia x tuberhybrida) are largely winter-flowering plants whose hybrids are grown as short term pot plants. After flowering, they are usually discarded. They tend to be available all year round due to improved cultivation methods.



All begonia types need bright, indirect light to grow in. Provide this and they will grow away quite happily. Give it shade and the flowering types will hate it. Begonias grown for the leaves will fare a bit better but will still struggle, Grow it in bright sunlight and the plant leaves will be bleached and will not look too attractive. So avoid bright, direct sunlight and avoid too much shade.


Begonias like to have water in the right quantities-not too much, not too little. Often too much is the biggest problem, where the roots will start to rot and fungal diseases can take hold. Avoid waterlogging at all costs, allowing the compost to dry out a little between waterings. It is best to water when 5cm below the top of the surface feels dry when you stick your finger into the compost.


Begonias do like the air that surrounds it to be humid, it will struggle in a very dry atmosphere near radiators. Do not mist the leaves or place in a wet atmosphere as the plant leaves hate constant moisture. You need to locate it in an area of high humidity.


They are not at all fussy about the temperatures they are exposed to, as long as it is above 10 degree Celsius and below 25 degree Celsius. Avoid freezing temperature that will kill the plant. As the plants grow, it will need to be repotted every couple of years or so to refresh the growing media and to allow the root to expand in the new growing media.

Rhizomatous begonias are an exception, they have shallow roots so it should be planted in shallow pots to avoid watering problems.


Begonias are hungry plants and will need feeding often when in active growth-once every month is ideal. For leafy begonias use a high nitrogen-based fertilizer, whilst for flowering types use a fertilizer with high potash.


All begonias will flower even those grown for their leaves. The blooms can appear at any time and can be long-lasting or for a short time. As some plant produces lots of flowers in succession that it can give a display lasting for weeks to several months.

Tuberous begonias will go dormant when the light gets shorter in autumn and winter. As the leaves turn yellow and drop off, it is best to cut off any remaining stems to just above the soil level. At this stage, do not water at all and once the soil has dried out completely, move it to a frost-free location for a few months until spring for some rest.
