Welcome! Happy you're here!
I've haven't grown Agastache 'Big Bazooka' before.
It sounds like the pinky-salmon one that smells so good must be Threadleaf Giant Hyssop (Agastache rupestris)
Threadleaf Giant Hyssop (Agastache rupestris)
Hardy to zone 4a and a favorite of mine and others. Very dependable every year. Take a look at the photos in the link. Its one of the taller (and older) varieties.
Here's our database on Agastaches, if you want to look at them.

High Country Gardens introduces their own and sells Agastaches.
http://www.highcountrygardens.... I've gotten a lot of my Agastaches there. They usually have a little more to offer in the Spring than what they have now.
To aid in winter hardiness....Don't cut back the old stems until you see new growth in the Spring. I wait until mid to late Spring before I cut back, in case we get a unexpected late frost/freeze. Agastaches prefer gravel mulches.
The newer and shorter Agastaches don't seem to grow, as well as, the older varieties for me. If I get those, I pot them up in a container for the Summer. I've grown Agastaches in containers for years, as well as, in the ground. Agastache rupestris is a great one for both types of growing.
