Overview

Syringa pubescens ssp. patula 'Miss Kim' is Miss Kim lilac, a compact mounding deciduous shrub growing 4-6 feet (1.2-1.8 m) tall and 4-6 feet (1.2-1.8 m) wide. Lavender-blue tubular flowers 0.3 inch (8 mm) from purple buds in dense conical panicles 3-5 inches (7-13 cm) in May-June — strongly fragrant (classic lilac fragrance with a spicy undertone). Blooms 1-2 weeks later than common lilac (S. vulgaris). Dark green simple ovate opposite finely pubescent leaves 2-4 inches (5-10 cm). Turns purple to burgundy-red in fall — one of the few lilacs with consistent fall color. In Oleaceae. Developed at the University of New Hampshire from Korean seed. Compact size (4-6 feet / 1.2-1.8 m) compared to common lilac (8-15 feet / 2.4-4.5 m). Powdery mildew on the foliage is the primary disease concern — develops in late summer on crowded plants with poor air circulation. This mildew susceptibility is the primary limitation. Lilac borer attacks stressed plants. Blooms on old wood — late winter pruning removes flower buds. Deadhead spent panicles. Deer browse. Non-toxic. Zones 3-8. Full sun to partial shade. Growth rate is slow.

Native Range

Subspecies S. pubescens ssp. patula is native to the Korean peninsula. 'Miss Kim' was developed at the University of New Hampshire from seed collected in Korea.

Suggested Uses

Grown as a foundation plant, low hedge, border shrub, and in containers of at least 10 gallons (38 L), spaced 4-6 feet (1.2-1.8 m). Compact lilac (4-6 feet / 1.2-1.8 m). Fragrant. Fall color. Space for air circulation (powdery mildew). Non-toxic. Zones 3-8.

How to Identify

Identified by lavender-blue fragrant flower panicles from purple buds on a compact mounding deciduous shrub with dark green ovate opposite pubescent leaves that turn purple to burgundy-red in fall. The compact size (4-6 feet / 1.2-1.8 m), the later bloom (1-2 weeks after common lilac), and the fall color distinguish 'Miss Kim' from S. vulgaris (common lilac — 8-15 feet / 2.4-4.5 m, no fall color). In Oleaceae.

Care & Maintenance

Care Guide

Full sun to partial shade (4-12 hours — full sun for dense bloom). Well-drained soil pH 6.0-7.5. Drought-tolerant once established. Powdery mildew in late summer — space for air circulation. Lilac borer on stressed plants. Blooms on old wood — do not prune in late winter. Deadhead spent panicles. Prune after flowering (June-July). Deer browse. Non-toxic. Zones 3-8.

Pruning

Prune after flowering (June-July) — blooms on old wood. Deadhead spent flower panicles to the first leaf pair below the panicle. Remove 1/3 of the oldest stems at the base annually for renewal. Do not shear. Remove any root suckers if a single-stemmed form is desired.
