About this plant
Common lilac originates in south-eastern Europe and needs a cold winter to bloom. Bloomerang hybrids are more compact, flower again after the main spring flush and have better mildew resistance. Lilacs make wonderful cut flowers.
Best spots
Sunny gardens, entryways where you can enjoy the scent, and large pots (Bloomerang) in cool climates.
