Syringa reticulata

Syringa reticulata

 

Common name: Japanese tree lilac

Family: Oleaceae

Leaf: Sharply tipped, lanceolate to ovate, opposite dark green leaves (up to 6" long). No fall colour. Reticulata means netted-veined in reference to the leaf veins.

Flowers: very showy, fragrant, creamy white flowers that bloom in upright panicles to 12" long in late spring to early summer (later than most lilac species).

Fruit: loose clusters of brown capsules that persist into winter.

Habit: small tree or large shrub; Form: oval-rounded crown

Height: 20-30'; Spread: 15-20'

Culture: Easily grown in average, medium moisture, well-drained soils in full sun. Tolerates light shade, but best bloom is in full sun. Prefers organically rich, moist, slightly acidic soils with good drainage. Needs good air circulation- otherwise can get powdery mildew. Good tolerance for urban conditions. To the extent practicable, promptly remove faded flower panicles before seed set- this helps next year's bloom. Prune as needed immediately after flowering. Best grown in cool summer climates, and not recommended for planting in the deep South below USDA Zone 7. Hardy in USDA zones 3-7.

Uses: Effective as a specimen in the landscape. Tree forms are effective along streets, in lawns, near decks/patios or in foundations. Shrub forms are effective in borders or small groups. May be used as a screen along property lines. Very attractive.

Origin: Northern China
