Syringa microphylla, commonly known as Littleleaf Lilac, is a deciduous shrub native to the limestone hills and scrublands of North and East Asia, particularly in regions of China. It typically grows to a height of 4-6 feet (1.2-1.8 meters) and a width of 10-12 feet (3-3.7 meters), with a compact, rounded form. The small leaves are what give this lilac its common name, and they provide a fine-textured appearance. Littleleaf Lilac is celebrated for its abundant clusters of fragrant flowers that come in shades of blue, pink, purple, and white, blooming in late spring. The flowers are highly showy and attract pollinators such as butterflies and bees.

This shrub is valued for its extended blooming period, ease of maintenance, and resistance to powdery mildew, a common problem in some lilac species. It is often used in border plantings, as a specimen plant, or for hedges in residential gardens. Littleleaf Lilac thrives in full sun but can tolerate part shade. It prefers well-drained soils and requires medium amounts of water, making it relatively drought-tolerant once established. While it is not known for aggressive roots or serious disease issues, it can be susceptible to lilac borer and scale insects. Pruning immediately after flowering helps maintain its shape and encourages more prolific blooms for the following season.CC BY-SA 4.0
