About
Begonia maculata (maculata meaning "spotted"), the polka dot begonia, is a species of begonia native to southeast Brazil. It grows naturally in the understory of the Atlantic rainforest, with occurrences confirmed in the Brazilian states of Espírito Santo and Rio de Janeiro. It has been introduced into Mexico, Cuba, the Dominican Republic, and Argentina.
How to grow it
B. maculata is a perennially popular houseplant. As early as 1871, the California Horticulturist described B. maculata as "a very desirable variety," and as recently as 2023, #begoniamaculata was the second most popular species-specific begonia hashtag on Instagram.
