Culture
Grow in average, medium moisture, well-drained soil in full sun. Tolerates light shade, but best bloom quality and disease resistance occur in full sun. Prefers rich, moist, neutral soils.

Noteworthy Characteristics
Syringa pubescens subsp. microphylla, commonly known as littleleaf lilac, is a dense, compact, mounded, spreading, deciduous, small-leaved shrub that grows to 6-7’ tall and to 12’ wide. Single, sweetly fragrant, lilac-pink flowers arranged in dense clusters (panicles to 4” long) bloom in May (St. Louis area). Elliptic to ovate, medium green leaves (to 2” long) are slightly hairy below. Synonymous with S. microphylla.
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 downy or hairy.
Problems
Littleleaf lilac is susceptible to powdery mildew, leaf spot and blight. Stem borer, scale and leaf miner are occasional insect pests.
Uses
Although spectacular when in full bloom, lilacs are otherwise somewhat ordinary shrubs. May be grown as specimens or massed. Also effective as privacy screens or hedges. Good for shrub borders or background for perennial borders. Foundations.
