21 Pretty Mock Orange Varieties

Philadelphus coronarius or mock orange is a deciduous shrub that has a rounded, dense growth habit. Most mock orange varieties feature serrated, oval, dark green leaves with pretty, four-petal, cup-shaped flowers in late spring or early summer. These shrubs come with a fairly quick growth rate that can easily grow two feet or more a year, and they’re best planted in early fall or in the early spring months.

The fragrant, lovely flowers your mock orange varieties produce are said to resemble orange blossoms, and this is how the mock orange name came around. They are rich with nectar that attracts pollinators like butterflies. Here, we’re going to outline several great mock orange varieties that vary in climate tolerance and sie but share the pretty floral appeal that all mock orange varieties have.
