Mock Orange is a hybrid deciduous shrub that typically reaches heights of 4 to 8 feet, featuring an upright and arching growth pattern. Its flowers are incredibly fragrant, appearing in terminal racemes with saucer-shaped blooms that can measure up to 1.5 inches across. This shrub thrives in moist, well-drained soil and prefers full sun to partial shade.

To manage its size, prune the shrub after it has finished flowering, and consider planting it near an entrance to fully appreciate its delightful scent.

Be aware that it may be prone to issues such as aphids, black spot, powdery mildew, and rust.
