The Q&A Archives: Descanso Variety Lilac Won't Bloom

Question: I purchased one of your Descanso Variety Lilacs a few years ago. It has been planted in a large container and gets full sunlight. It grows a few leaf buds during spring, but has never bloomed. The lilacs at Descanso Gardens are in full bloom right now, but my plant looks barely alive. Any suggestions?

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.
