Begonia is one of the largest genera of flowering plants with over 1900 species. They are pantropic plants which means they are found naturally in tropical and subtropical regions around the world, except Australia.
Begonias are terrestrial plants. In the wild, they can either grow in stems, rhizomes, or in tubers. Begonia plants have distinct foliage. Their leaves are large and asymmetric with various patterns and prominent venation.
Another distinct feature of begonias is their flowers. Begonias are monoecious, which means the flowers are unisexual with both male and female flowers blooming separately on the same plant.
The flowers have tepals that vary in color depending on the variety. Begonias flower year-round, except some tuberous species.
Because of their luscious foliage and spectacular blooms, begonias are now popular among gardeners and homeowners alike. They are perfect plants for both indoor and outdoor use.
Most begonias available in garden centers are hybrids between wild types. Ornamental begonias can be foliage or flowering and are categorized in the following groups based on their root structure.
Fibrous-rooted begonias are annual plants that have round and waxy leaves and small flowers.
They are one of the most common ornamental begonias because of their prolific flowering which makes them perfect bedding plants. This group includes cane (angel wing) begonias and wax begonias (Begonia × semperflorens-cultorum).
This group is popular for its spectacular rose-like flowers that come in bold pastel colors. They bloom annually every midsummer to winter. Tuberous begonias are perfect either as bedding or container plants (2).

Rhizomatous Begonias are herbaceous plants cultivated mainly for their foliage. Begonia plants from this group have leaves that vary in size and pattern and grow from rhizomes, hence the name.
They are particularly used indoors as potted houseplants or outside as container plants, hanging plants, or bedding plants.
