Noted for its unique colour, award-winning Syringa vulgaris 'Primrose' Lilac is an upright, deciduous shrub with conical panicles of slightly fragrant, pale creamy-yellow flowers. Blooming in late spring, the ravishing blossoms last 3-4 weeks and make a rare and beautiful display. The erect, open branches are clothed inlight green, heart-shaped leaves that remain attractive in summer. To extend the season of interest of your lilac, grow clematis with different bloom times through its branches to add colour and glamour to the shrub.
