How to Grow and Care for Painted Tongue
Plant Overview
The Painted Tongue, scientifically known as Salpiglossis sinuata, is a vibrant flowering plant that belongs to the nightshade family. Native to South America, particularly Chile and Argentina, this annual plant is cherished for its stunningly colorful, trumpet-shaped flowers that can brighten any garden. The plant typically grows to a height of 1 to 2 feet and features lance-shaped leaves that are a deep green, providing a beautiful contrast to its vivid blooms.
Optimal Growing Conditions
Light Requirements
Painted Tongue thrives in full sun to partial shade. Ideally, the plant should receive at least 6 hours of direct sunlight daily. In extremely hot climates, providing some afternoon shade can prevent the flowers from wilting.
Temperature
This plant prefers moderate temperatures and flourishes best in the range of 60°F to 75°F (15°C to 24°C). It’s important to protect it from frost, as it is sensitive to cold conditions.
Soil
For optimal growth, Painted Tongue requires well-draining soil rich in organic matter. A pH level of 6.0 to 7.0 is ideal. You can enhance soil quality by mixing in compost or well-rotted manure.
Watering
Keep the soil consistently moist but not soggy. Water the plant deeply when the top inch of soil feels dry. During hot summer months, more frequent watering may be necessary, but ensure that the pot or garden bed has good drainage.
Humidity Requirements
Painted Tongue prefers moderate humidity levels. If grown indoors, consider placing a humidifier nearby or grouping it with other plants to create a more humid microclimate.
Seasonal Care Tips
Spring
In spring, as the danger of frost passes, it’s time to plant your Painted Tongue outdoors. Prepare your garden bed by tilling the soil and mixing in compost. If starting from seeds, sow them indoors 6-8 weeks before the last frost date.

Summer
During the summer months, ensure that the plant receives adequate water and deadhead spent flowers to encourage continuous blooming. Fertilize every 4-6 weeks with a balanced fertilizer to promote healthy growth.
Fall
As temperatures begin to drop, reduce watering and prepare your Painted Tongue for the cooler months. If you live in a colder climate, consider bringing potted plants indoors.
Winter
In winter, Painted Tongue will typically die back in colder climates. If grown indoors, maintain a cool temperature and reduce watering. If the plant has been brought indoors, ensure it still receives adequate light.
Common Issues & Solutions
Pests
Common pests that affect Painted Tongue include aphids and spider mites. Regularly inspect your plants and treat infestations with insecticidal soap or neem oil.
Diseases
Powdery mildew can be a problem, especially in humid conditions. Ensure good air circulation around the plant and avoid overhead watering to minimize this issue.
Yellow Leaves
Yellowing leaves can indicate overwatering or nutrient deficiency. Check the soil moisture and adjust your watering schedule accordingly. If the soil is too wet, allow it to dry out before watering again.

- Remove the lower leaves and dip the cut end in rooting hormone.
- Plant the cutting in a pot filled with well-draining soil.
