Syringa reticulata
'Boulevard'
Boulevard Japanese Tree Lilac
"
A narrow, upright cultivar of the the very popular S. reticulata 'Ivory Silk'. A very popular tree when in flower in late June or Early July, the 6.5 m tall trees are covered in very airy, light cream panicles, its flowers for several weeks with the entire tree covered in bloom. In seems pollution tolerant and is often used in urban environments; however it will never develop a large canopy because of its relatively small stature. It has a broadly obovate canopy and is used to great effect in alleys, lining paths and sidewalks. It has a somewhat unpleasant scent when in flower.
