The easy-to-grow and fragrant lilac was brought from Europe to New England by the early colonists. Today this “Queen of Shrubs” is ubiquitous in Massachusetts.
Better Homes and Gardens notes that:
“Lilacs are known for their hardy nature and long lives—many lilac shrubs live to be more than 100 years old. Because of their life span, they often survive longer than the home of the gardener that planted them. So, if you’re on a country road and see a few seemingly-random lilac bushes, there was most likely a house or farm there in the last century.”
