A young plant may not bloom for several years.
Blooming may be retarded by too much nitrogen – such as lawn fertilizer. Will grow in less than full sun, but bloom is diminished and susceptible to mildew.
Removal of spent flowers will result in a neater appearance and more bloom the following year. Any pruning to control size and shape should be done immediately after flowering.
Most varieties require sufficient winter chill to bloom. A few selected varieties will bloom in mild winter areas (zones 8 and 9).
Some varieties will self-sow.
As it can take 5 or more years to grow a lilac bush to blooming size from seed, growing from seed is uncommon.
A more common propagation method is to dig up a side shoot from an existing plant.
Plant in a well drained location that gets at least 6 hours of sun. A 2" mulch layer will help preserve soil moisture and control weeds.
Lilacs are very long lived plants and can become rather large so choose the location carefully.

Lilacs are frequently featured in poetry and song, such as T. S. Eliot’s poem “The Wasteland”, which begins:

Dull roots with spring rain….”
