It is probably a garden escape and there are a couple of other similar varieties so would agree it may be this one or it could be Aster x frikartii "Monch" but I don't think the flower heads are dense enough for Aster nova-belgii
Useful to know that, I just guessed from the list on iSpot.
Also helped with my iSpot demonstration.
