Iris foetidissima

in The potting shed
Having just seen Monty Don describe how to propagate by division Iris foetidissima and how it will survive well in a dry shady spot, I excitedly ordered some plants online. Only afterwards did I discover that it is a pretty much indestructible and invasive weed.  I am confused and scared this might turn into a monster that I will regret.   I need advice, please.

    I've never found it invasive.  It's always just sat where I put it, not spectacular in flower but really attractive when the seed heads open.   :)
    Since 2019 I've lived in east Clare, in the west of Ireland.

    I quie like the subtle flowers. I've never thought of propagating it, but leave it if it lands in a good place. There's a rather nice one growing out of the slabs in the corner of my patio.😊
    In London. Keen but lazy.

    Phew... that's a relief, thank you.

    Perhaps it's not invasive in the UK then and that a relief 😃

    Not invasive in this garden ... grows happily in this garden, increasing in size slowly, but in 8 years the clump is no bigger than 12”x12” at the most. 

    Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.

    We have a small clump which has been in situ for over 16 years, hasn’t spread and only got a bit larger over the years. Not a problem.

    The yellow one, on the other hand, though beautiful, is a real thug!
    I spent hours on Wednesday removing them from part of my bog garden. Leaves cut off filled  the barrow, roots filled 2 sheep feed bags to the top, just from an area less than a square metre!

    But that is a totally different species, I.pseudoacorus.
    How can you lie there and think of England
    When you don't even know who's in the team

    Plant in a large aquatic basket sunk into the ground.. no guarantees but seems to have kept mine in check. I'll check later this year when I split them.
