Syringea vulgaris 'Monge" (Lilac) is an upright, deciduous shrub with incredibly showy panicles, 9 in. long (22cm), packed with wonderfully fragrant, single, reddish-purple flowers. Blooming in late spring, the abundant blossoms last 3-4 weeks and make a dramatic display. The flowers are held on long stems that lend themselves to great cut flowers. The erect, open branches are clothed in blue-green, heart-shaped leaves that remain attractive in summer.
