Torenia is a variety of annual flowering plants that do not grow very large yet still make a significant impact on an outdoor space. Also known as Wishbone Flower due to the stamens that grow in pairs and resemble a wishbone, the showy bi-color blooms tend to have a dark eye, creating a colorful and dramatic look.
The flowers grow on upright stems that also bear pointed green foliage with darker undersides for an unexpected and subtle pop of color. Torenia can thrive in partial shade and blooms all summer long for a consistent source of color and pollinator activity. Follow these tips for healthy plants.
What You Need To Plant Torenia
- Compost or manure
- Garden spade
- Good location
- Water source
Where to Plant Torenia
Plant Torenia in an area that receives partial sunlight or partial shade. A spot with morning light and afternoon shade is best, especially when grown in warm climates. Soil should be rich and well-drained with a slightly acidic to neutral pH. Drainage is vital because soggy soil is pretty much the only major issue for this annual. Plant at a depth, so the top of the root ball is even with the surrounding soil.
Space Torenia plants about 8 to 9 inches apart. This plant has an upright growth habit and will grow more tall than wide, although it is relatively small in stature. Torenia will spread about 8 to 9 inches wide and can be planted against other plants or buildings.
Steps To Plant Torenia
Step 1 - Find a spot that receives partial sun, as direct sunlight can be damaging
Step 2 - Dig a hole about 2 to 3 times as wide as the root ball and slightly deeper
Step 3 - Mix manure or organic compost into the soil
Step 4 - Place the root ball in the prepared hole, and position the top of the root ball even with the ground level
Step 5 - Backfill the hole and firmly press the ground into place
Step 6 - Drench the soil around the plant to saturate the roots
When to Plant Torenia
As an annual, Torenia cannot handle chilly temperatures, so plant in the spring well after the threat of frost has passed. Mornings are generally a good time to plant, especially when grown in higher light levels.
Transplanting is generally unnecessary for Wishbone Flower plants as this plant is an annual and will die back after the first frost. If you want to move your Torenia from one spot to another during the growing season, dig around the plant to minimize damage to the roots and replant in the desired location.
