Types of begonias

Take your pick: begonias can be annuals, evergreen or deciduous perennials, or shrubs. The leaves often have striking patterns while the clusters of flowers offer everything from the simplest white or cream petals to the most showy double-flowered blooms in eye popping colours. 

Tuberous types look great tumbling out of containers, while others, like B rex ‘Benitochiba’, are worth growing for their dramatic leaves alone. 

Traditional bedding types of begonia 

These can be used in containers, window boxes and at the edges of borders, providing long-lasting displays that can be planted out once the danger of frost has passed. 

Look out for some of the newer varieties too, such as the ‘Million Kisses’ range. These tend to feature much more delicate-looking, single, bell-shaped flowers. 

Hardier begonias 

These aren't so easy to find, but there are some, such as B grandis, that cope with temperatures a couple of degrees below freezing. Planted in well-drained soil and given some protection they can survive outdoors over winter. 

These begonias combine attractive foliage with daintier flowers than those of the more common bedding cultivars. They really come into their own in late summer and autumn, when their blooms add a splash of colour to a shady spot.

Late winter and spring is a good time to order bedding begonias from specialist growers and the range is vast. 

If you’ve got a warm, sunny windowsill or a heated greenhouse you can grow them from seed or tubers. 

Otherwise plug plants from the garden centre or online are an easier option. Plant out when risk of frost has passed.

Where to plant begonias

Begonias love tumbling out of containers, window boxes and hanging baskets. Or plant them as a mass of eye catching colour in borders, where they'll also do well. Choose a spot that's in sun or partial shade for best results. They love fertile soil that's moist and free draining.

If you're choosing a hardy variety, plant them in rich, well-drained soil in a sunny, sheltered position. If you live in an area where the climate is milder in winter, plant them in the shelter of a south-facing wall and they can be left in the ground.

  1. As a rule, begonias need a moist but well-drained soil. They are native to forests and, consequently, favour dappled sun or part shade in preference to full sun.
  2. Bedding begonias and those grown in containers should be watered regularly and fed weekly with tomato fertiliser. 
  3. In autumn, lift bedding begonias grown from tubers before the first frost, trim top growth to 6cm, remove compost and leave to dry before storing in a dark, frost-free shed or garage in dry compost. Repot in spring. 
  4. Bedding begonias grown from seed or plugs should be treated as annuals and composted once they’ve gone over.
  5. Mulch hardier begonias with chipped bark, or lift them out, pot up and overwinter in a conservatory or greenhouse.

Common problems with begonias

  • Well-drained soil is key as your plants may rot if the ground is waterlogged. If they're planted in containers standing them on pot feet also helps as it lets water drain away rather than accumulating around the base.
  • Move your plants into the shade on scorching hot days, as the foliage may burn if left unprotected. If they're planted up in borders in full sun use your garden umbrella to shade them temporarily.
  • If the flowers drop off it could be a sign that you're not watering regularly so make a note to be more consistent.
  • If you notice your plants are dusted with white this could be powdery mildew. Trim off the affected foliage and if need be use a chemical fungicide. Make sure your plants aren't too close together so air can circulate.


Classic bedding begonias come in a wide range of shades and foliage types. Choose them for pots, patio gardening ideas, hanging baskets and window boxes as well as borders.

If you’d like to add some fragrance to your pots and window boxes try ‘Lemon Fizz’, which matches a sweet, citrus aroma with pretty lemon-yellow, double flowers. 

Plant these magnificent trailing begonias up with ferns and choose a spot in dappled shade to add some vibrance that will last throughout summer and well into autumn.

This new variety has a bushy, semi-trailing habit and a profusion of single, bell-shaped flowers. White with a blush of pink, the delicate blooms top contrasting red stems, and sit amid dark green, arrow-shaped leaves.

Plant this cultivar for cascades of double flowers, in crisp white with the softest hint of peach, on pink stems.

Compact and bushy, this variety is ideal for pots. The bronze-green foliage forms a neat mound above a mass of fiery orange, star-like flowers that bloom throughout summer as it's exceptionally long flowering. Add it to your garden to create a glow from midsummer right round to autumn.

The gorgeous ruffled double flowers have a carnation-like appearance with layers of white petals, each edged with deep pink.

It’s a robust variety of begonia and will happily keep on flowering whatever the summer weather throws at it.

This one is a real stunner. It's an old variety of begonia that has really stood the test of time. The dark green leaves act as the perfect foil to large, single flowers with deep red petals encircling golden yellow centres. These large showy blooms will smother the plant all summer long. 


Begonias are equally famed as one of the best indoor plants. Grown for their gorgeous foliage and known as cane-stemmed and B rex types, these are tender varieties that need to be treated as houseplants, although they can be moved outdoors during summer if the conditions are right. 

A good choice for a shady bathroom, houseplant begonias like some humidity. Use soft tap water or rainwater, and wait until the compost is almost dry before watering.

The dramatic deep green leaves have darker edges that form a spiral, swirling into the centre of the leaf. The foliage also has the distinction of being covered in tiny red hairs, particularly noticeable on young leaves.
