    I grew these from seeds a few years ago, huge plants always covered in bees, I’ve got blue and white, very hardy. Blue Giant Hyssop (Agastache foeniculum) 

    Having said that...lost them all in this year’s frosts 😢

    I was quite surprised that all mine came through fine despite the colder-than-normal winter. Some of them are from @Lyn's seeds. I expect they like the dry sandy soil that they get here.

  • I have a lot of different  agastaches  and usually keep them in pots. last winter I put 4 in my sunny borders.3 survived .the white and paper ones seem to do better than the deep purple ones.ive lost 2 black adders tho even in pots and they hate the cold.

    In the ground, the shrubby aurantica types seem to make it through my cold mountain winters, but I regularly lose the taller lilac ones like Black Adder and Blue Boa and only managed to get two cuttings to survive in an unheated poly tunnel. So a greenhouse would give you a fighting chance 😊
