Torenia

toe-REE-nee-ah
Torenia fourieri 'Clown' series

The Torenia genus is made up of 40 to 50 species of bushy annuals and perennials from high altitudes in tropical Africa and Asia.  Torenia have showy, 2-lipped flowers with yellow throats. These plants are great for summer bedding or at the front of a border or in pots. They also can be grown as a houseplant or in a cool greenhouse.

Noteworthy CharacteristicsTubular, flaring 2-lipped flowers with yellow throats. The species has purple, two-toned flowers, while various cultivars have pink, white, or lavender blooms.

CareOutdoors, provide Torenia with fertile, moist but well-drained soil and partial shade. Indoors, they need bright filtered light and good ventilation. Water freely and fertilize during active growth. Pinch out stem tips to promote bushiness.

PropagationSow seed in mid-spring at 64°F and plant out after the frost-free date.

ProblemsRoot rot, Botytis, and powdery mildew sometimes occur.
