Tougher and later blooming than the common lilac, Miss Kim lilac is an attractive compact deciduous shrub with a pleasing mounded to round form. It has soft green foliage that turns purple-red to maroon in the fall. In late spring to early summer, it puts forth many upright panicles of fragrant, pale purple flowers that are dark purple in bud. The following year’s flower buds are set shortly after flowering, so prune directly after it blooms.
This selection of Machurian lilac is an ideal shrub for foundation plantings or shrub borders. Its smaller size is lovely in cottage gardens or as an informal hedge. It needs well-drained, average soil that isn’t acidy and in full sun for best flowering. In regions with warm winters, expose this shrub to coldest winter winds to allow for best flower bud formation. It may also be helpful to provide lightest hints of shade in the hottest afternoon summer sun.

Select a site with full sun and moist, well-drained soil.
Plant in spring or fall. Space plants 5 to 15 feet apart, depending on variety. Dig a hole only as deep as the root ball and 2 to 3 times as wide. If your soil is in very poor condition, amend the soil you’ve removed from the hole with a small amount of compost. Otherwise don’t amend it at all. Carefully remove the plant from the container and set it in the hole. Fill the hole half full with soil, then water it well to settle the soil and eliminate air pockets. Let the water drain, then fill the remainder of hole with soil and water thoroughly.
Apply a layer of compost under the plant each spring, followed by a 2-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than 1 inch per week. Prune lilacs immediately after flowering, removing dead and broken branches, then cutting back as necessary to maintain the desired size and shape. Overgrown lilacs can be pruned back by as much as one third.
