Philadelphus

Mock Orange
Hydrangeaceae (Philadelphaceae)
Deciduous, Evergreen, Shrubs

Prized for their white or cream-colored, usually fragrant flowers that bloom in late spring or early summer. Blossoms are four petaled, typically 1–2 in. wide; they range from single to fully double. Plants are generally large and vigorous, with a fountainlike form. Oval, 2–4-in.-long leaves (typically medium green in color) are arranged in pairs along the stems. Prune every year just after bloom, cutting out the oldest wood and surplus shoots at the base. To rejuvenate, cut to the ground. Taller types are striking planted in lawns and as background and corner plantings; smaller kinds can be used near foundations or planted as low screens or informal hedges. Buy this plant in bloom to check for the best fragrance. Not fussy about soil type but must have good drainage.
