These 'apples' are peeled and eaten when they are soft, and are described as being fragrant, juicy, and tasty.[1] The formation of galls was originally thought to be limited to Salvia pomifera,[13] which led to the misidentification of many gall-bearing Salvia fruticosa plants.[14] In 2001 it was discovered that the galls on Salvia fruticosa were caused by a previously undiscovered genus of Cynipid gall wasp.[15]
