  1. Hi folks, just to clarify since I only know ageratum as an annual, this hardy ageratum is a perennial? Thanks, Mary

    • Mary, this Ageratum is a perennial, and is hardy in zones 5-8. I was of the belief before that it was only hardy through zone 6, but that is incorrect.

  2. THIS IS A BEAUTIFUL PLANT, I BOUGHT IT AS A PERRENIAL PLANT. THE PROBLEM IS IT HAS SPREAD ALL OVER MY GARDEN. NOT TOO HARD TO PULL OUT WHERE NOT WANTED, BUT A LOT TO PULL OUT.
    I WISH I HAD KNOWN IT WOULD SPREAD LIKE THIS.

    • Carol, thanks for your comment. It can spread, but here in zone 6A, it has never been a thug. Where do you live?
