of the most popular purple lilacs is the Syringa vulgaris,
or common purple lilac. This purple lilac is hardy to zones
three through seven. It prefers full sunlight, just as all
lilac plants do. The common purple lilac will grow to a mature
height of eight to ten feet, with an equal mature spread.
The upright form of this purple lilac makes it a wonderful
candidate for a privacy screen. The fragrance emitted by this
purple lilac is one of the most powerful scents from any flower.
It works well as a hedge or accent plant.
highly requested purple lilac is the Persian lilac. This purple
lilac is hardy to zones three through seven as well, and has
wonderful lavender blooms. Growing shorter than the common
purple lilac, the Persian will reach a height of only about
four to eight feet. The shorter height makes this purple lilac
a great choice for a border or foundation planting. The arching
branches of this purple lilac make it look very graceful,
even once the foliage has fallen off in the winter.
third popular purple lilac is the Chinese lilac. This purple
lilac has lavender blooms that sometimes acquire a slightly
pink hue. Also hardy in zones three through seven, this purple
lilac has an upright, rounded form. They will reach a height
of six to twelve feet with an equal mature spread. Used as
a single specimen, this purple lilac produces an excellent
floral display in early May.
