Description

Philadelphus 'Pearls of Perfume' is a mock orange with a flair for the dramatic, offering not only masses of luminous double blooms but also a scent that can rival any classic rose. This compact deciduous shrub, reaching around 1.2m in height, has a naturally upright, columnar habit that keeps it tidy while still delivering an extravagant display. The dark green, oval leaves provide a handsome backdrop for its white, pearl-like flowers, which appear in generous clusters from May right through to August. Unlike many of its cousins, the blossoms of Philadelphus 'Pearls of Perfume' don’t just concentrate at the tips—they stud the entire length of each branch, creating a striking garland effect.

Placed in borders, pots, or as a feature plant on a terrace, Philadelphus 'Pearls of Perfume' never fails to deliver charm in abundance. Its fragrance is sweet, citrusy, and almost nostalgic, evoking summer evenings spent in cottage gardens and adding an irresistible sensory dimension to its visual appeal. The fact that this mock orange blooms for such an extended season means it works hard for its space, offering reliable flowers and perfume at a time when many shrubs are past their best. Robust yet graceful, Philadelphus 'Pearls of Perfume' earns its name with ease, providing a shimmering, scented display that turns the ordinary garden into something a little more enchanting.

Philadelphus is called mock orange because its sweet, citrusy fragrance closely mimics that of real orange blossom, though it bears no fruit.

Useful information

    • Soak the Philadelphus 'Pearls of Perfume' roots in water for 3-6 hours prior to planting

    • Plant your "Mock orange" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors

    • Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).

    • Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
