Wishbone Flower Care

Torenia Fournier Plant Wishbone Flower Care Guide Requirements

Wishbone flowers are fairly easy plants to care for that can thrive with the right attention. Here are some essential care tips:


Wishbone Flowers favor a little bit of shade. If maintained continually moist, they can withstand direct sunlight. Otherwise, under direct sunlight, especially in warm weather, their leaves may wilt quickly.


Well-drained soil is crucial. The ideal mix should consist of equal parts sand or perlite mixed with peat moss or coconut coir. Regularly add small amounts of compost throughout the growing season. Mulching around young plants helps keep roots cool while retaining optimal moisture levels. Water only when the top layer feels dry to ensure water reaches deeper without causing root rot.


Wishbone flowers thrive in consistently moist soils. During peak bloom times like early summer, provide extra water on days where temperatures reach above 80°F due to increased evaporation rates.

Temperature & Humidity

These annuals prefer temperatures ranging from 60°F to 80°F and humid environments. Consider misting the leaves regularly or placing a tray of water nearby.


Feed wishbone flowers regularly with balanced plant food every two weeks during peak growing season, from spring through early fall. Avoid over-fertilizing to prevent leaf burn or stunted growth.

Pruning Wishbone Flowers

Deadhead spent blooms to encourage new flower growth and maintain neatness. After flowering stops each year, pinch back the stems until spring to promote a bushier habit.

How to Propagate Wishbone Flowers

Use cuttings taken in the late summer before the first frost to propagate. Inserting the cuttings into well-draining potting soil after dipping them in rooting hormone powder. Keep them out of direct sunlight and give them plenty of water. Wrap the roots in plastic to keep the surrounding area moist. Before transferring the young seedlings outdoors, gradually increase light exposure once they have taken root.

How to Grow Wishbone Flowers from Seed

Sow seeds directly outdoors just before the last frost date in your climate zone. Alternatively, start the seeds indoors six to eight weeks before the last frost date. This allows young plants to establish healthy root systems and gain strength before transplanting. Provide ample light exposure during the indoor growth period, using grow lights if natural sunlight is limited.

Overwintering Wishbone Flowers

Wishbone flowers are annuals and can’t survive winter months outdoors in many climates. However, they can be overwintered indoors. Bring your plant inside just before the first frost of the season and place it in a sunny window. Water as needed throughout the dormant period until spring returns.

Typical Pests & Plant Illnesses

Wishbone flowers, like the majority of plants, are prone to aphids and other pests and illnesses like spider mites. Spraying neem oil or insecticidal soap on your plants will stop them in their tracks. If you experience pest issues, speak with a local nursery expert for recommendations on best practices based on practical local remedies.

How to Get Wishbone Flowers To Bloom

The key is creating optimal growing conditions! Give your wishbones plenty of light (partial shade is best), consistently moist soil, and regularly add compost to the top layer. Avoid over-fertilizing, which may cause leaf burn or stunted growth. Instead, use a balanced fertilizer applied at two-week intervals throughout the growing season. Deadheading spent blooms also encourages new flower growth and helps maintain a neat appearance.
