Overview
Wishbone flower, or torenia, is one of the best annuals for adding color to shady spots where many flowering plants struggle. Its small, trumpet-shaped flowers are often beautifully two-toned, with a velvety throat and a brighter contrasting face.
The common name comes from the pair of stamens inside each bloom that arch together to form a tiny wishbone shape. It blooms from summer to frost, thrives in heat and humidity, and is equally at home in beds, borders, and containers.

Ornamental: A top choice for shade gardens, shaded containers, hanging baskets, and porch boxes where sun-lovers fail; the bicolored blooms add color and detail up close.
Ecological: The tubular flowers attract bees, butterflies, and hummingbirds.
Frequently asked questions
Why is it called wishbone flower?
Inside each bloom, two stamens arch together to form a small wishbone shape, visible if you look into the flower's throat.
Can wishbone flower grow in shade?
Yes, it is one of the best flowering annuals for part to full shade, though it appreciates some bright indirect light.
Does torenia need deadheading?
Many modern varieties are self-cleaning. Light deadheading keeps plants tidy but is not essential for bloom.
Why are my wishbone flowers wilting?
It needs consistently moist soil. Drying out, especially in too much sun, causes wilting and poor flowering.
