Easily grown in average, medium moisture, well-drained soil in full sun. Tolerates light shade, but best bloom occurs in full sun. Prefers organically rich, moist, slightly acidic soils with good drainage. Needs good air circulation. Tolerates urban conditions well. To the extent practicable, faded flower panicles should be removed prior to seed set. Prune as needed immediately after flowering. Best growth typically occurs in cool summer climates. Not recommended for planting south of USDA Zone 7.
Syringa reticulata, commonly called Chinese tree lilac, typically grows as a small tree or large shrub. In tree form, it grows to 30’ tall and 20’ wide with an oval-rounded crown. Its best ornamental feature is its showy, fragrant, creamy white flowers which bloom in upright panicles to 12” long in late spring to early summer (later than most other lilac species). Some gardeners dislike the privet-like smell of the flowers. Flowers give way to loose clusters of brown capsules that persist into winter. Reddish-brown peeling bark is attractive on younger branches, gradually turning gray with age. Sharply-tipped, lanceolate to ovate, dark green leaves (to 6” long). No fall color.
Genus name comes from the Greek word syrinx meaning tube or pipe in reference to the pith-filled but easily-hollowed stems of some genus plants.
Specific epithet means netted-veined in reference to the leaf veins.
