Begonia rex 'Etna' – high-contrast spiral foliage with volcanic color intensity

Begonia rex 'Etna' delivers bold, dramatic foliage with a textured spiral shape and intense coloration that ranges from dark crimson to near black. Each leaf features a wide swirl of fiery red radiating from the base, framed by irregular metallic silver and edged in deep, serrated margins. The surface is slightly puckered and matte with a velvet texture that shifts tone under light. This compact rhizomatous grower stays low but spreads wide, making it ideal for focal plantings in bright indoor spaces without direct sun exposure.

Extra styling tips and display
'Etna' stands out in modern or maximalist interiors, especially when placed in contrasting pots that highlight its intense foliage. It works best solo or in loose groupings with more muted greenery, allowing the fiery tones to dominate. Use a wide, shallow pot to let rhizomes spread, and give it room to breathe.
Etymology and cultivar meaning
“Begonia” honors Michel Bégon, a French botanist. “Rex” means king, referencing its dominant foliage. The cultivar name ‘Etna’ draws from Mount Etna, a volcano in Italy, reflecting the plant’s deep red tones and intense, almost eruptive leaf patterns.
