Philadelphus lewisii, Mock Orange

This desirable, deciduous native shrub is covered in a mass of white blossoms at the height of flowering in late spring, attracting bees and butterflies. Mock orange is widespread but not common, usually appearing as an individual plant in a mix of other species.

The shrub sends out long stems, which are red when new and fade to gray with age. Its leaves are light green in color with a rough texture, generally turning a lovely yellow in fall. The large flowers bloom in clusters at the ends of long stems and have a heavy, sweet scent similar to citrus blossoms. They are among the most fragrant flowers of any California native plant.

Mock Orange can get 6–8 ft. tall and wide with a vaguely umbrella shape. It flowers on last year’s wood, so prune immediately after blooming. It is fast-growing and tolerates almost any soil type, making it a wonderful focal plant in a garden. Give it full sun to light shade and moderate to occasional summer water. Tolerant of clay soil.
