It’s called Aromatic Aster (Symphyotrichum oblongifolium), though I certainly don’t notice any scent. But this Aster is a beauty, scent or no scent. Native to the northeastern and central US. Host plant to Silvery Checkerspot Butterfly.
A great time to be blooming, providing nectar and pollen to insects when other flowers have already finished their seasons.
And as summer turns to autumn Aromatic Asters add a marvelous color to the landscape. Purple, to go with the oranges and yellows. A perfect color combination.
