Lilacs are common landscape plants, and while lilac shrubs get most of the attention for their colorful and fragrant flowers, tree lilacs, while lacking fragrance, have their own merits. The Japanese tree lilac (Syringa reticulata) has been grown for years as a multistemmed, medium-sized tree. It's equally effective in the home landscape and as a street tree. Now there is a tree lilac that features not only the billowy, creamy white flowers in early summer, but attractive bark as well.
'Copper Curls' Pekin lilac (Syringa pekinensis 'SunDak') is a 20- to 25-foot-tall single or multistemmed tree with the same white flowers as the Japanese tree lilac. Plus, 'Copper Curls' features curly, coppery orange, peeling bark that adds interest to this tree in fall and winter. 'Copper Curls' Pekin lilac, like the Japanese tree lilac, is hardy to USDA zone 3, adaptable to a wide range of growing conditions, and has few insect and disease pests.
