Since colonial days, the common lilac has been in America one of the best loved of the flowering shrubs, meriting its favor by its cone-shaped masses of lavender or white flowers, its fragrance, and its ease of cultivation.

From this old-fashioned common lilac (S. vulgaris) and others, many hybrids have been developed with variations in form (such as double flowers) and in color (such as rosy pink and white). These hybrids, which may lack the fragrance of the common lilac, are often called French lilacs because much of the pioneer hybridizing was done in France. The most famous use of the lilac in poetry is Whitman's elegy on Lincoln, "When Lilacs Last in the Dooryard Bloom'd."
