Polka Dot Begonia

Begonia maculata

Also known as Trout Begonia, Spotted Begonia

Polka Dot Begonia anchors itself in the humid shade of the Brazilian Atlantic Forest, displaying striking olive-green leaves peppered with metallic silver spots and rich crimson undersides. Clusters of delicate white to pale pink blossoms droop from tall bamboo-like stems throughout the warmer months. As a classic rainforest understory plant, it thrives in high humidity and dappled light away from harsh direct sun.

Why interaction risk is high
Toxic to dogs and cats if ingested; keep out of reach of pets.
Why it is dangerous
Contains insoluble calcium oxalates throughout the foliage and stems that cause intense oral irritation, drooling, and vomiting if swallowed by pets.
How to recognize a risky encounter
Look for asymmetrical olive leaves dotted with silvery white spots, dark red undersides, and jointed cane stems.
What to do
Position high on shelves or in hanging planters well out of reach of domestic animals.
Responsible observation
  • Lighting: Position in bright indirect light to preserve the intense red underside coloration.
  • Humidity: Provide ambient humidity above 50 percent to prevent brown leaf tips.
  • Pruning: Pinch back tall stems in spring to encourage bushy growth.
