This plant can be invasive in some regions. If you see a white, sugar-like substance on the leaves and stems of Ruellia, it could be erineum, a growth distortion caused by tiny mites called eriophyid mites. This will usually not cause too much harm to the plant other than some distorted leaves which can be pruned off.
