First time post. I am a total Agastache FREAK, and have been for years. I have a half dozen or so different species/varieties out in my different gardens, down from around 10 last year. My favorite (and favorite plant of all time), year in, year out, is Anise hyssop. I've probably got 50 of them scattered around my place. The Agastache that has totally broken my heart, though, is the Kudos series. One year, they will be my "medal winners", and I'll think, "Alright, I'm going to be enjoying these forever and ever!" Then the next year - POOF! - they're gone, or the stands are severely weakened and puny by comparison with the previous year. I don't get it. I have a beautiful true loam soil, we have a fairly mild climate here in the Arkansas Ozarks, and I have them lightly mulched. The two that absolutely killed me were the Kudos Gold and Kudos Ambrosia: stunningly beautiful and healthy one year, hardly there or gone completely the next. What's up with that? What am I doing wrong? What do I need to do???
BTW, I grow true hyssop as well, and it's doing great. Not the world champion pollinator magnet that the Agastaches are, but pretty darn nice! Also, seems like Veronica (corn speedwell) would fit in nicely with this forum; the flower form is similar to salvias and agastaches, but tighter.
