Mock Orange (Philadelphus)
Mock orange (Philadelphus coronarius) is a deciduous shrub that has a dense, rounded growth habit. It sports oval, serrated, dark green leaves and features showy, cup-shaped, four-petal flowers in the late spring and early summer. Mock orange shrubs have a fairly quick growth rate and can gain around 2 feet per year. They are best planted in the early fall but also can be planted in the spring.
