Deciduous & Flowering Shrubs

Mock orange

Philadelphus hybrid 'Virginalis'

Philadelphus 'Virginalis' is a deciduous mock orange grown for very fragrant white flowers, double to semi-double, in late spring and early summer. Its long, arching canes form a multistemmed shrub that generally reaches about 5 to 10 feet tall and wide at maturity. Plant it near a path or seating area to enjoy the fragrance, or give it room in a mixed border or informal screen. Full sun brings the strongest flowering, though partial shade is suitable. Average garden soil works when it drains well, especially through Southwest Washington's wet season. Older stems can be removed after flowering to renew growth.

The right plant, the right place

Make room for something good.

The fragrant flowers suit a mixed border near a path or seating area. Its arching form also works in an informal screen or hedge.

Where to plant

Give the shrub about 8 to 10 feet of room. Choose full sun for the best flowering, or a site with partial shade.

Through the seasons

Fragrant white double to semi-double flowers appear in late spring to early summer. Older canes develop peeling bark.

Southwest Washington gardens

Give it a good start.

In Southwest Washington, pay attention to drainage during wet months. A brighter location will support a fuller flower display.

Soil, drainage & water

Average garden soil is suitable when drainage is adequate. Avoid a site where winter water remains around the roots.

A little care goes a long way

Growing well, season after season.

Prune soon after flowering, when the season's display ends. Remove some of the oldest stems near the ground to encourage new canes.
