Common Lilac features showy panicles of fragrant lilac purple flowers rising above the foliage in mid spring. The flowers are excellent for cutting. It has bluish-green deciduous foliage. The heart-shaped leaves do not develop any appreciable fall color.
Common Lilac is a multi-stemmed deciduous shrub with an upright spreading habit of growth. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage.
Common Lilac will grow to be about 12 feet tall at maturity, with a spread of 9 feet. It tends to be a little leggy, with a typical clearance of 3 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 30 years.
This shrub should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is not originally from North America.
