begonia plant and flowers

Flower plants can give an enormous amount of solace and begonia makes no exception. Begonia flowers are vibrant, diverse, and stunning. They are available in various shapes and colors, adorning gardens and interiors with their beauty and charm.

Here is our guide to learn how to grow begonia, a wonderful tropical plant that has around 1,600 different species.

Begonia is a perennial plant of tropical origin, belonging to the Begoniaceae family. The name comes from a botany enthusiast, Michel Bégon, who was also the governor of Santo Domingo.

This plant is appreciated for the beauty of its flowers, very diverse and colorful.

Begonia classification

This plant is commonly classified into three large groups:

  • Tuberous begonias
  • Fibrous-rooted begonias (also known as fibrous begonias)
  • and Rhizomatous begonias

However, there is a characteristic that we find in every species: the presence of male and female flowers on the same plant (monoecy).

The tuberous begonia is made up of tubers accompanied by very colorful stems and flowers. This plant is not suitable for growing in the garden, but prefers growing in an apartment. During the winter season it enters the vegetative rest phase.

Fibrous begonias, on the contrary, are ideal for outdoor cultivation. They produce flowers in spring and throughout the summer season.

The rhizomatous begonia is mostly found indoors and appears as an evergreen shrub. The root consists of a rhizome and its flowers are generally not very brightly coloured.

Begonia care: practical advice

This plant needs a few simple precautions depending on the species it belongs to. To ensure that it blooms well, it must be placed in a sunny place, but where the rays are not too direct, otherwise many small dark spots on the leaves will form.

Both for cultivation in the garden and for cultivation in pots, the soil must always be enriched with natural fertilizer and must be well moist.

In the case of gardens, bury the bulbs about 3 cm deep in the months of April or May. While in the pot, prepare a base of at least 5 cm with expanded clay, arrange the bulbs and then cover with soil and peat.

Watering will be abundant in summer and reduced during winter. The tuberous variety is the only one that requires lower amounts of water.

We always advise you to wait until the soil is dry before proceeding with the next watering. This will prevent the formation of dangerous waterlogging.

You don’t need to prune the plant, but simply remove the dry leaves.

Do begonias like the sun or shade?

Although begonias adapt well to different light conditions, they generally prefer light shade or part sun, that is a few hours of morning sun and shade in the afternoon. However, different varieties of the flower in different climates might suggest different degrees of direct exposure to sunlight.

The flowering of this plant is linked to the subspecies it belongs to. Some plants can flower all year round, others begin with the arrival of the warm season and continue until the first winter frosts appear.

  • The male flowers are more showy and have four tepals divided into pairs of different sizes.
  • The female flowers on the contrary have four equal tepals (They are called tepals and not petals because there is no difference between the corolla and calyx of the flower).

Let’s now discover the main species widespread in our apartments and gardens.

Begonia: what is the meaning of the flower?

Begonia is commonly given as gifts to friends to mark friendliness and hospitality, so it makes a great gift to bring when going to someone’s home. In South American countries it is instead associated with wealth.

In the nineteenth century it had a completely different meaning: giving this plant with flowers of two different colors was a symbol of hypocrisy. Today it is used a lot to purify environments, so much so that NASA scientists have classified it among the species to be saved for life inside aerospace stations.
