Begonia 'Silver Jewel' is a cross between Begonia imperialis x pustulata. It is a rhizomatous perennial grown mainly for its stunning foliage. Leaves are heart-shaped, asymmetrical, with a puckered surface. They are metallic silver with dark green radiating markings. Bears clusters of cream flowers.

Genus name was established in mid 18th century: modern Latin, named in honour of the French administrator and amateur botanist Michel Bégon (1638–1710) by the botanist Charles Plumier (1646–1704), who discovered the plant on the island of Santo Domingo.
