Q. Why doesn’t my lilac bloom in the spring?

A. There are several possible reasons why your lilac fails to bloom. The most common cause is lack of adequate sunlight. Lilacs (Syringa) need to be planted in a location that receives at least six hours of strong, direct sun per day. They are very tolerant of different moisture conditions as long as they are planted in well-drained soil.

Species that are known to change color in cold weather include:
