'Cricket Song' on Tuesday 10-23 opening its first fall bloom.
Looks like 'Harvest of Memories' wants to be next and the pinkish volunteer (that is probably from 'Cricket Song') is also racing to catch up.
We've had light frost (enough to totally kill the pumpkin foliage but not enough to totally freeze the tomatoes).

Here's a link with another picture and a little more babbling.
