Wishbone Flower (Torenia fournieri) is a dainty and delightful little flower that can take heat, humidity and shade. There are not many annuals that can accomplish that! You can usually find torenia available as a bedding plant, but you can also start from seed inside. You’ll need to do this in the winter, 10-12 weeks before the last frost. If you are in a mild climate you can grow torenia year round as long as it doesn’t get below about 28-30 degrees.
One torenia can cover a 12″ square area if planted in the garden, but you can plant them closer in containers. They make great plants for windowboxes, pots and hanging baskets as long as you don’t allow them to dry out between waterings. Moisture and shade in very hot climates are a must for torenia. Given this they will bloom constantly from early summer until frost if deadheaded.
