Answer: Lilacs generally require a pronounced winter chill in order to bloom. Descanso hybrids are an exception, blooming well without a winter chill. In your mild winter climate, your choice of a Descanso hybrid was a good one! Lilacs can sometimes take 7 years to become established and mature enough to bloom. Continue to give your lilac TLC and, when it's old enough, it will bloom for you.
