I found these plants today and I'm not sure what they are. I recall having some agastache a long time ago, but not had any for a long time. I'm wondering if some long dormant agastache  seed has germinated? I'm asking as it could be something I bought in the autumn,  planted   and have completely forgotten what it was! So asking before digging out.

    It looks like mint. Do the leaves smell when crushed?  Is the stem square in cross-section?

    Thank you. Oddly it has no smell and the stem is round. I'll hold fire on digging it out for now as sometimes I've planted things in the autumn and completely forgotten, so get a spring surprise!

    I had a campanula lactiflora that looked similar as it came out of the ground.

    oh yes I did have some camp lactiflora that I planted around there,  and maybe I   moved them in a bit in the autumn. another one has come up in a different part which I definitely did not plant there. Maybe they seed freely?

    I had C. lactiflora Prichard's Variety which I think may be sterile. I never found seedlings. I had it for 4-5 years then it vanished.
    But I bought some mixed C. lactiflora seed that I'll sow next month. I hope they do seed freely as I really like them.

    They do seed fairly freely. I have 2 to move today. One seeded in a pot and is easy, the other is larger and is growing right next to a large flagstone that I will need to lift to remove the roots. Not easy at all!

    That's good to hear.
    The seed I have is in a plastic vial - and looks like a few bits of dust - so that's going to be a challenge to sow. The slightest hint of a breeze and they could go anywhere - I'll have to hold my breath when sowing - knowing me I'll probably sneeze 😁
    Good luck with moving your tricky one!
