Answer: Phillipine Violet is Barleria cristata. The name commemorates the French botanist, Jacques Barrelier. The inappropriately-named Phillipine violet is a native of India. The flowers are pale violet-blue. It will grow in full to partial shade in soil that is moist to wet. Expect a mature height of 4'-6' tall with equal width. The plant is hardy to Zone 9. Given winter protection, Phillipine violet will grow in your zone 5 garden.
