Torenia bicolor, the two-color wishbone flower, is an annual herb found in the western and southern India as well as the Andaman Islands,[1] where it grows mainly in moist and waterlogged areas. The plant has slender, four-sided stems with small hairs near the nodes. Leaves are small (1.5–3.5 cm long), triangular to oval in shape, with toothed edges and a pointed tip, and are carried on short stalks.[2]
Flowering and fruiting
Flowers grow singly or in pairs from the leaf axils, on stalks up to 3 cm long. They are about 2–2.5 cm in length, with a yellowish tube and deep purple lobes. The calyx is green and ridged, partly forming wing-like extensions. The plant has four stamens joined in pairs at the tips, creating a wishbone-like structure, which gives rise to the common name “Wishbone Flower.” It flowers throughout the year.[3]
The fruit is a small, oblong capsule, about 1–1.5 cm long, containing round, rough-textured seeds.
Uses
Torenia bicolor is widely regarded as a model plant in ornamental and transgenic research.[4]
