What Is Torenia? A Comprehensive Overview

Torenia is a hardy annual or short-lived perennial belonging to the Gesneriaceae family, native to Asia and the Himalayan region. Known scientifically as Torenia fournieriana, it’s prized for its unique, tubular flowers that resemble tiny bells—typically pink, purple, or white. Often called “partridgeflower” due to its dappled petals resembling bird markings, Torenia is celebrated for its adaptability, especially in shaded environments where many summer blooms struggle.
