I think I have finally mastered growing Sinningia tubiflora, one of the many new 'hardier' gesneriads, those plants in the African Violet family, which are getting more and more collectable by those in-the-know. This week, my gravel container garden has been overcome by a magnificent specimen, which, I have to admit, was an accident. This Sinningia tubiflora is growing in a deep terra cotta pot, and its become essentially, a giant lemon scented air freshener, yes, its evening fragrance lingers across the garden in our hot, humid summer weather.
