Blue blossom, also known as California lilac, is a fabulous showy broadleaf evergreen shrub. Lilac colored flowers bloom in mid to late spring and have a wonderful fragrance. Native to coastal northern California and southern Oregon, it is drought tolerant and deer tolerant and easy to grow. It can grow up to 20 feet tall in the wild but usally does not grow more than ten feet tall in an urban landscape. It responds well to pruning. Like all broadleaf evergreens, it can get die back during a very cold winter.
