Flowers of Night are deep purple and single. This species is the common lilac, also referred to as French lilac, that most of us are familiar with; extremely fragrant flowers on 4 to 8 inch dense panicles, appearing in late spring to early summer. Prefers a neutral soil, with peat or leaf mold enrichment. The following years' flower buds are produced by midsummer, so if pruning is necessary, do so before July.
