Native to tropical areas of Asia, Torenia is a bushy plant that typically reaches a height of seven to 12 inches and spreads out six to eight inches. This compact plant is not aggressive or invasive, making it a perfect addition to any garden.

The flowers of Torenia are reminiscent of snapdragons and foxgloves and belong to the figwort (Scrophulariaceae) family, now considered a member of the Linderniaceae family. The plant blooms from early summer to mid-fall, attracting hummingbirds to its sweet nectar.

Torenia’s nicknames, such as wishbone flower, bluewings, and clown flower, reflect its unique characteristics and colorful appearance. When planting Torenia, consider companion plantings such as impatiens and ferns to create a harmonious garden space.

Propagating Torenia

You can propagate Torenia by purchasing starts from a local nursery or starting from seeds. When selecting plants, look for sturdy specimens that are not yet blooming to ensure successful transplantation.

If starting from seeds, sow them indoors six to eight weeks before the last frost date. Transplant the seedlings into the garden after the last frost, ensuring they are placed in well-draining, moist, organically-rich soil. Water regularly and fertilize with high-phosphorus plant food to promote healthy growth.

Cultivating Wishbone Flowers

Torenia thrives in part shade locations with well-draining, fertile soil. It’s essential to provide adequate moisture without overwatering to prevent root rot and powdery mildew. Fertilize the plants once or twice a month during the growing season to support their growth and blooming cycle.

Growing Tips:
Choose a part shade location.
Plant in well-draining, fertile soil amended with aged compost.
Fertilize monthly with high-phosphorous plant food.

Pruning and maintenance of Torenia are minimal, with the plant naturally maintaining a compact, attractive form. Pinch back young plants to encourage branching and remove faded plants at the end of the growing season.

Where to Find Torenia

Avoid overwatering to prevent root rot and powdery mildew, maintaining the plant’s health throughout the growing season.
