Syringa patula
Manchurian lilac is a medium‑sized species that flowers a bit later than common lilac. It bears lilac‑purple clusters that often fade toward pink as they age. Plants show good mildew tolerance compared with many older lilacs. Foliage can turn purple‑red in fall. The shrub fits small hedges and mixed borders where a compact, fragrant lilac is desired.
