|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 Jan van Tol are pure white, single, and borne on 14 inch long panicles. This species is the common lilac, also referred to as French lilac, that most of us are familiar with; extremely fragrant flowers 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. Native to eastern Europe, cultivated since 1563. Over 400 cultivars have been developed.
