Annual best grown in consistently moist, organically rich, well-drained soils in part shade to full shade. Although sometimes classified as a warm weather annual, this species of Torenia is not terribly fond of hot and humid summer weather. In the St. Louis area, it needs protection from the hot afternoon sun and benefits from a summer mulch to help retain moisture and keep soils cool. As long as properly sited and watered, it will generally bloom from early/mid summer to frost. Start seed indoors 6-8 weeks before last frost date or sow seed directly in the garden just before last frost date. Plants are often available from nurseries in cell/six packs. Set out seedlings or purchased plants 1-2 weeks after last frost date. Young plants may be pinched to promote compact, bushier growth. Container plants may be brought indoors for winter bloom.
