The Begonia Maculata, often called "Trout Begonia" or Polka-Dot Begonia, is a spectacular houseplant that brings an exotic atmosphere into your home. With its unique leaves, dressed in a striking polka-dot pattern, this plant adds a touch of artistic extravagance to any environment. A fascinating feature of this plant is its growth habit as a "bamboo begonia" with upright, knotty stems. The deep green color of the leaves is complemented by silvery-white dots and a strong deep red hue on the underside, creating a dramatic contrast. The stems are robust and resemble bamboo, which gives the plant an additional dimension.
Typical characteristics:
-
unique, asymmetrical leaves with silver dots ("Polka Dots")
-
deep red undersides of leaves (a real eye-catcher)
-
produces pretty white or pink flower panicles with good care
-
creates a tropical, inspiring atmosphere
