Known for its vibrant, trumpet-shaped flowers, Torenia adds a splash of color to gardens and containers. The plant typically grows to about 12 inches in height and spreads up to 6 inches wide, making it an excellent choice for borders and hanging baskets.

Origin and Appearance

Torenia originates from tropical and subtropical regions across Asia and Africa. It features lush green foliage and striking flowers that come in shades of purple, blue, pink, and white. The unique wishbone-shaped stamens of the flower give the plant its common name.

Growth Habits

This plant thrives in warm climates and is often used as a bedding plant. Torenia is known for its compact growth habit, making it ideal for small spaces and container gardening.

Optimal Growing Conditions

Light Requirements

Torenia prefers partial shade to full shade, making it perfect for areas where other flowering plants might struggle. It can tolerate some morning sun but should be protected from the harsh afternoon sun.

Temperature and Humidity

Torenia thrives in temperatures between 60°F to 75°F (15°C to 24°C). It enjoys high humidity, so consider misting the plant or placing it near a humidifier if grown indoors.

Soil Needs

Watering Requirements

Keep the soil consistently moist but not waterlogged. Water the plant when the top inch of soil feels dry, ensuring good drainage to prevent root rot.

Seasonal Care Tips

Spring

Begin planting Torenia seeds indoors about 6-8 weeks before the last expected frost. Transplant seedlings outdoors once the danger of frost has passed.

Summer

Maintain regular watering and feed with a balanced liquid fertilizer every 4-6 weeks to encourage continuous blooming. Keep an eye out for pests like aphids and spider mites.

Fall

As temperatures drop, reduce watering and prepare to bring any potted Torenia indoors if you wish to overwinter them.

If kept indoors, place Torenia in a bright spot away from drafts. Reduce watering and avoid fertilizing during the dormant period.
