Begonia maculata, the Polka Dot Begonia, is a striking cane begonia famous for its olive-green wing-shaped leaves dotted with silvery-white spots and deep maroon-red undersides. Native to Brazil, it grows upright on bamboo-like canes and produces clusters of dainty white flowers in the warmer months. It enjoys bright indirect light, moderate humidity and well-draining soil, and is reasonably easy once watering is balanced. Its bold colour and pattern make it a popular Instagram-worthy houseplant. In Indian homes it grows well indoors near a bright window, away from harsh sun and cold drafts.
