Begonia ruthiae x kapuashuluensis

This rare, unnamed interspecific hybrid brings together two exceptional Bornean Begonias: the bullate, finely textured character of B. ruthiae and the thick, metallic foliage of B. kapuashuluensis. Young leaves may display pale marginal spotting before developing a more oblique mature shape, while the surface produces remarkable structural iridescence rather than ordinary variegation. It is an especially compelling specimen for collectors fascinated by foliage that transforms with light and perspective

Grow this hybrid in a terrarium or greenhouse cabinet with bright, gentle light, consistently high humidity, and steady warmth. Use a fine, airy substrate that retains light moisture while draining freely, and water before it dries completely without leaving the roots saturated. Aim for approximately 75–90% humidity with gentle airflow, protecting the plant from direct sun, cold drafts, stagnant wet foliage, and abrupt humidity changes. Feed sparingly during active growth. Begonias are toxic if ingested, so keep this plant away from pets and children.
