Philadelphus × purpureomaculatus is a flowering plant in the family Hydrangeaceae, of garden origin.

It is a hybrid between Philadelphus × lemoinei and P. mexicanus 'Rose Syringa'.

Growing to 1.2 m (4 ft) tall by 2 m (7 ft) broad, it is a deciduous shrub with broadly oval leaves up to 5 cm (2 in) long, and single, cup-shaped flowers in summer (June in the Northern Hemisphere).

The flowers, which are strongly fragrant, are pure white with prominent purple markings near the centre;[1] hence the Latin specific epithet purpureomaculatus, literally "purple spotted".

[2] Valued in the garden as a summer-flowering shrub, the cultivars 'Sybille' and 'Belle Etoile' have gained the Royal Horticultural Society's Award of Garden Merit.
