Torenia, widely known as Wishbone Flower, is a genus of about 15 species in the family Linderniaceae, native to Africa and Southeast Asia.
This charming plant produces oval or heart-shaped leaves and beautiful bright flowers in shades of purple, blue, pink, yellow and white. These unusual, trumpet-like flowers are two-lipped, with prominent markings on their petals. The plant is suitable for use in garden beds and borders, as well as containers.
The genus name is given in honor of Swedish botanist Olaf Toren (1718-1753), who was chaplain of the Swedish East India Company in the mid-1700s.
The common name “Wishbone Flower” comes from the two stamens united at the anthers, forming a structure that resembles a chicken wishbone.
The common name “Bluewings” refers to its wing-shaped petals.
These brightly colored flowers also resemble a face of a clown, hence the common name “Clown Flower”. This is especially true with the pink, yellow and white varieties.
Torenia symbolizes happiness and charm.
