About Begonia 'Joe Hayden'
Begonia × 'Joe Hayden' · also called joe hayden begonia, rhizomatous dark begonia · houseplant
Begonia 'Joe Hayden' is a rhizomatous hybrid famed for very dark, near-black star-shaped leaves with red undersides and a glossy, almost metallic sheen. It spreads from a creeping rhizome and throws up sprays of pale pink flowers in late winter to spring. Give it bright indirect light, moderate humidity, warmth, and careful watering to keep the dark foliage rich.
Preferred mix: Light, airy, free-draining mix
Watch for — Rhizome rot: Overwatering or a buried, soggy rhizome causes soft mushy rot. Keep the rhizome on the surface and let the mix dry slightly between waterings.
