Torenia fournieri is a bushy, annual plant. It is a small plant that grows about 12 inches tall and 6 to 8 inches wide. Torenia fournieri is a valuable addition to gardens that do not receive full sun.

Growing Torenia fournieri

Torenia fournieri seeds should be planted in warm, moist soil 6 to 8 weeks before the expected last frost date. These plants do not transplant well. Therefore, seeds should be started in paper pots or peat. The seeds should not be covered in soil because the seeds cannot germinate without sunlight. The soil should be maintained at about 70 degrees Fahrenheit and should be reasonably moist. Once the seeds germinate, they can bear cooler temperatures.

If you wish for your Torenia fournieri plant to grow bushier, pinching the tip of the growing plant can help you achieve it. In areas that are frost-free, you can sow seeds into the outdoor soil directly. This should be done at least a week before the last frost is expected.

Planting and Propagating Torenia Flowers

Torenia flowers can be grown by seeds or by seedlings. Seeds are usually sown indoors before the expected last frost. They can also be sown outdoors directly when the temperature of the soil has turned fairly warm. If you wish to use seedlings for Torenia propagation, you can allow the seedlings to grow indoors and then transplant the seedlings carefully to the soil outside.

Germination of Torenia Seeds

Seeds of Torenia flowers require sunlight for germination. Therefore, when you sow the seeds in your garden, do not cover the seeds with soil so that the seeds remain exposed to sunlight.

Soil Requirements

Torenias require soil that is moist, well-drained, and fertile. Adding compost to the soil can also improve the growth and quality of the blooms. The pH of the soil should be slightly acidic – between 5.6 to 7.5. Adding a layer of mulch is also beneficial for Torenia growth.

Light Requirements

Light is a very important factor in the growth of Torenia flowers. These plants require both sun and shade. If Torenia plants are grown in an area where there is only shade, Torenia flowers may not bloom at all. If the plant is grown in an area that receives full sun, the foliage may develop a faded-green color. Therefore, the ideal spot to plant Torenia is an area that receives morning sun and afternoon shade.

Water Requirements

Torenia requires moist soil to grow. If you plan on planting Torenia flowers, you will be required to water the plant regularly. However, make sure that you do not overwater because if the soil becomes soggy, the roots may rot and the Torenia plants may die.
