Iris or crocosmia

I have crocosmia in amongst some iris. I want to take out the crocosmia, but now that the flowers are gone, how do I get the right plant by leaf identification alone?

    Water the clumps generously and leave to soak for an hour then lift clumps with a fork.

    The iris - assuming they're bearded - will have horizontal tuberous roots like a piece of ginger.  The crocosmia will have stacked round corms.  Separate them carefully, cut off any dead ends of the iris rhizomes, trim their leaves back to a third and re-plant each root.   Iris like to have their rhizomes baked so don't plant them deep.

    If they are Siberian irises they will grow in clumps you can separate by hand or with a fork or spade and you can easily spot the crocosmia corms.  Re-plant the new clumps at the depth they were before and don't trim the leaves.

    Dutch irises have a bulb at the base and you can separate those, with their leaves attached, and re-plant at the same depth after separating the crocosmia.

    Thank you. I was hoping not to have to take them all up, but no such luck!

    It'll be better for the irises if you do take them up - a form or regeneration.   Not difficult to do.

    Will do.
  • I have a mixed bed of these that I just relocated.  In my experience the crocosmia leaves are softer and narrower. The iris leaves feel firmer and are slightly wider.

    That's great thanks.

    Depends on the Iris though. The foliage on many of the other types isn't like bearded irises   :)

    Thanks all. I think when the weather gets cooler I'll need to dig them up and have a good look!

    Good decision and it will be worth the bother.
