Philadelphus is an elegant, classic flowering shrub.


It’s long been been a garden favourite for its white blooms, which are deliciously scented, giving it the common name of mock orange. These beautiful pure white flowers appear in late spring and summer against a smart backdrop of dark green foliage. A medium-sized deciduous shrub, philadelphus will suit most gardens with the right, sunny growing conditions.

It’s sometimes considered to be a one-hit wonder, as it does tend to fade into insignificance once the flowers have gone over. But if you have room, it’s worth including in any successional display of summer blooms and scent.

Take a look at our comprehensive philadelphus Grow Guide, below.

Where to grow philadelphus

Philadelphus grows best in moist but well-drained soil in full sun. A mature philadelphus will look good growing in a mixed border. But it will also do well planted in a large container, near seating or near a doorway where you can make the most of the fragrant flowers.

Planting philadelphus

Plant philadelphus as you would any larger shrub. Dig a generous hole, adding a spadeful of well-rotted compost and a sprinkling of mycorrhizal fungi. Back fill the hole, firm the soil and water in well.

To keep philadelphus shrubs in shape, cut back the shoots after flowering, down to a strong bud. Flowers appear on stems from the previous season’s growth, so if you have to hard prune an older, established philadelphus, be prepared to lose out on the flowers for a year or so while it recovers. Follow our step-by-step guide to pruning spring flowering shrubs.
