Welcome!
Russian Sage (also known as Perovskia). Even though it has Sage in its name, it isn't a Sage/Salvia.
Filigran, 'Longin' and 'Little Spire' I think are the latest blooming. Not sure about the others.
Here's our Perovskia database listings:

Perovskia is a Perennial and you might want to ask your questions in the Perennials forum, so you can get the info you want better answered.

Hope this helps.
