I thought this was my agastache, but I'm not so sure...

Last year I added an agastache foeniculum to my perennial garden- I planted it in late August and it flowered for me soon after and into the fall. This spring I had two plants that came up in the same area, which I assumed were the agastache returning since the plants had square stems and opposite, toothed leaves. Now that we are into July, the plants are taller than me and I am also noticing that the opposite leaves are compound-- so I'm not so sure this is agastache after all. Any ideas who this is?

    Looks right even if tall. Did you crush a leaf and do a smell test?

    I mostly smell a very faint mint/planty smell when I crush a leaf, but I've never grown it before, so I'm not sure whether I'd recognize the smell, which I know is supposed to have hints of licorice.

    Looks like agastache to me. It must like it's spot to grow that tall. Someone told me once they thought it smelled like root beer!

    I’m not seeing any compound leaves in the pictures.

    I could be describing it wrong. What I see is that instead of just two opposite leaves off the main stem, it's two opposite stems, each of which have multiple opposite leaves. I just assumed it was a compound leaf, but maybe agastache branches like that.

    Yes it does.

    Never, ever heard of or seen A. foeniculum that tall. Let us see it when it flowers.

    Looks like it likes its growing conditions.

    Update- it's starting to bloom! Agastache or not?



    Also, it's about 8' tall by now. At least.

    @Jay 6a Chicago Oh, interesting! I bet you're right. I am wondering if it was maybe just mis-labeled at the nursery. I bought it during one of the last days of a going-out-of-business sale, so it's quite possible. I looked more closely and I can definitely see fine hairs on the stems. The underside of the leaves does seem somewhat white, but I'm really not getting an anise scent when I crush/smell them. I'm happy that it's such a valuable pollinator plant despite being less showy. It's in a decent spot for the height, so if this persists in my garden, I'll call it a win.

    I went and looked at my Purple Giant Hyssop and the pubescence is the same as on your plant. I think when they are smaller and younger, they have more hairs. The underside of the leaves is a slighter lighter shade of green than the topside. The undersides of Agastache foeniculum leaves are also a lighter green, and not white like some sources state.

    Thank you for the helpful comparison photos- I think that cinches the ID.

    Agastache foeniculum's maximum height is 3.5'

    May be rather average? Mine is 5.5' and still getting taller.

  • Jay 6a Chicago

    Maximum heights

    Ladybird - 4ft.

    Wiki 4ft

    Flora of British Columbia 36"

    Illinois Wildflowers 3.5ft.

    Windberry, go take a picture of yours with a tape measure, or otherwise I tend not to believe you.

    My tallest is 5 foot even, so Windberry’s is reasonable.

  • Jay 6a Chicago

    I can believe 5 feet, but 8 feet I don't think so. These are all reliable sources I quoted. Still want to see a picture.

  • tsugajunkie z5 SE WI ♱

    Windberry said theirs was 5.5 feet not 8 feet.

    Sorry for the late response Jay. We have raging fires here, and visibility is less than 1 km so forgive me bad quality pics. I was a little unprecise writing that my Anise Hyssop is 5.5' tall. Right now the one close to the Beebalm is 5' 5" and the other one is 5'11". Will try to get better pics when the outdoor conditions are better.

    Jay,

    Sorry I didn't do it earlier, but here they are, the requested pics of my Anise Hyssop with the tape measure showing how tall the plants are (6 and 1/2 feet). Now I will prune the flower stalks with already ripening seeds and get rid of all the plants but one (I have more of them growing in my edible garden). They are crazy re-seeders.
