You are describing Syringa pekinensis (Chinese or Pekin Tree Lilac), which is a relative of the more commonly planted (some places) Syringa reticulata (Japanese Tree Lilac). It is an exceptional addition to the garden as a summer blooming large clump/shrub or smaller tree.

Not sure that there are any native Lilacs to North America - but it may seem like it where the plant is used a lot. The Japanese Tree Lilac is becoming a staple plant for urban plantings (especially under power lines) due to its tolerance of heat/drought and resistance to pests.

I like the exfoliating bark on Syringa pekinensis 'China Snow'.
