A Little Early
The common lilac often blooms in the late spring or early summer. This is a bit ahead of roses, and other flowers since those often bloom in late summer, but it depends on your variety. Some lilacs bloom right before spring or early in the season. In the early 20th century, Isabella Preston bred 52 new varieties that bloom late and could survive the Canadian spring.

Not Native Stateside
Syringa vulgaris might be widespread in the country, but it is not actually native to the United States. The common lilac actually comes from the Balkan Peninsula. Over there, it grows on the mountainsides. Botanists only found out about this in the early 19th century, a long time after the fragrant plant had already been introduced to Europe and exported across the pond.
