Syringa vulgaris ‘President Grevy’ – Highly fragrant double lavender-blue flowers emerge from pink-tinted buds (forming 6-10″ long panicles), usually starting early to mid May. These are borne over mid green heart-shaped leaves that often shift to yellow in the fall. It is important to deadhead spent blooms after the flowers have faded. Grows 10-12′ high by 6-8′ wide. Zone 3.
Syringa vulgaris ‘Beauty of Moscow’ (syn. Krasavitsa Moskvy’) – One of the most fragrant French Lilacs with pale pink buds opening to shell pink to white double flowers that stand out well against the dark green foliage. This Russian cultivar was introduced back in 1943 and produces 7-9″ long panicles. Prune immediately after flowering. Grows 10-12′ high by 6-7′. Z3.
Syringa vulgaris ‘Acubaefolia’ – Something a little different for a French Lilac, as the heart-shaped mid green foliage is randomly splashed with golden-yellow, much like some Aucuba japonica. It produces fragrant lilac blue flowers (which are double) from purplish-pink buds. This sport of ‘President Grevy’ should have all ‘solid green’ shoots pruned out. Grows 10′ high by 6-7′ wide. Z3.
Syringa vulgaris ‘Lila Wonder’ – If you’re a fan of the bicolored blooms of Syringa vulgaris ‘Sensation’, then this newer introduction is for you. ‘Lila Wonder’ bears variegated single blooms of pale lilac-pink with clear white margins, usually in May. This large deciduous shrub works well to anchor the corners of backyard fences. Grows 8′ high by 6′ wide. Hardy to zone 3.
Syringa vulgaris ‘Congo’ – This cultivar of French Lilac produces the quintessential display of fragrant reddish-purple blooms (fading a pure purple) that emerge from darker buds. It is slightly more compact than other Syringa vulgaris cultivars, with a rounded growth habit. Prefers well-drained neutral to alkaline soils. Grows 8-10′ high by 6-8′ wide. Hardy to zone 3.
