|Syringa vulgaris is a leggy, suckering, deciduous shrub, somewhat irregular in shape. Leaves are medium green, ovate to heart-shaped, up to 5 inches long. Flowers of Ami Schott are cobalt- blue and double. This species is the common lilac that most of us are familiar with, extremely fragrant lilac 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' buds are produced by midsummer, so if pruning is necessary, do so before July. Fine for the shrub border, not really a specimen plant. Native to eastern Europe, cultivated since 1563.
Over 400 cultivars have been developed.
