Sub-category: Olive family
A large deciduous shrub or multistemmed small tree, growing to 6 to 7 m high, producing secondary shoots from the base or roots, with stem diameters up to 20 cm, which in the course of decades may produce a small clonal thicket. The bark is grey to grey-brown, smooth on young stems, longitudinally furrowed, and flaking on older stems. The leaves are simple, 4 to 12 cm and 3 to 8 cm broad, light green to glaucous, oval to cordate, with pinnate leaf venation, a mucronate apex, and an entire margin. They are arranged in opposite pairs or occasionally in whorls of three. The flowers have a tubular base to the corolla 6 to 10 mm long with an open four-lobed apex 5 to 8 mm across, usually lilac to mauve, occasionally white. They are arranged in dense, terminal panicles 8 to 18 cm long. Flowers are extremely fragrant and sweet-smelling. The fruit is a dry, smooth, brown capsule, 1 to 2 cm long, splitting in two to release the two-winged seeds.
A very popular ornamental plant in gardens and parks and residential landscaping. Blooms early summer.
