Begonia seed | Begonia Genus Overview
LATIN NAME: Begonia COMMON NAME: Begonia Genus Overview
Botanical Profile
The genus Begonia is one of the largest genera of flowering plants in the world, comprising well over a thousand species native to tropical and subtropical regions across Asia, Africa and the Americas, displaying an extraordinary diversity of leaf shape, colour and growth habit, from small trailing groundcovers to substantial shrub-like specimens. Most species favour warm, humid, shaded conditions typical of tropical forest understorey, and flowers, while often smaller than the foliage suggests, add colour to what is primarily a genus prized for leaf beauty.
Science & Conservation
The sheer species diversity within Begonia has made it a significant subject of plant systematics research, with new species still being described regularly, particularly from biodiversity-rich tropical regions of Southeast Asia and South America, making it one of the more actively studied genera in modern tropical botany. Ornamental begonia breeding has also become a substantial horticultural industry in its own right, with breeders working across the genus’s naturally enormous diversity to develop new leaf patterns, colours and growth forms for the houseplant and bedding plant trade.
Landscape & Practical Uses
Begonias are grown worldwide as houseplants, greenhouse specimens and summer bedding, valued across the genus for an extraordinary range of foliage colour and pattern alongside generally delicate, though often abundant, flowers. Different sections of this vast genus suit very different growing situations, from tender tropical species needing warm, humid indoor conditions to a handful of genuinely cold-hardy outdoor perennials such as Begonia grandis.
Growing From Seed
Sow the extremely fine seed onto the surface of a loose, humus-rich, well-drained mix without covering it, since light is essential for germination and the seed is too fine to bury successfully. Warmth, high humidity and bright but indirect light suit most begonia species well during germination, and covering the tray with clear plastic to maintain humidity often improves results considerably.
Our Take
We would treat this general listing as a jumping-off point rather than a final purchase – with such enormous variation across the genus, we think most buyers will get a better result choosing a named species suited to their specific climate and growing space.
