    Meh. Mum had a big clump of it in her garden in Truro. It was (probably still is) rampant but it wasn't that hard to keep it in its clump, just had to be watchful and pull it up if it sprouted elsewhere, like most pernicious weeds.

    But don't let it out the gate because it does do real harm once it's gone feral.

    The RHS use both names for all cultivars so it is not surprising that there is confusion. The troublesome montbretia is a hybrid, crocosmia x crocosmiiflora. It is an offense under the Wildlife and Countryside Act 1981 to plant or otherwise allow it to grow in the wild so it must be disposed of appropriately. 

    I have it in my garden and find it easy enough to keep under control.

  • I planted my Monbretia corms in pots then planted the pots in the flower bed - so far so good, the pot is containing the Monbretia. However after seeing Crocosmia Lucifer in a garden this year I have planted this too - it looks far superior to the Monbretia although they both seem to have the same spreading habit.

    I built an extension over mine. That seems to have worked.....image

    I pull up any bits that stray too far but the common one doesn't seem to big an issue here. It's hard to kill though. Pots are a good method - as GD does - and you could also confine it with old paving slabs or similar, sunk vertically into the ground. It prevents the corms spreading sideways so easily.

    Lucifer and the other named varieties are less invasive usually.

    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...
  • An extension,now there's an idea Fairy, but I have done with building work - had enough to last a couple of lifetimes! Photos, you want photos aym - I know you have seen this one before and these Monbretia are not contained in any way because I want them to spread in this particular area of the driveway.imageAren't they lovely, they are still there now although the flowers have finished, but the leaves still look attractive with their arching structure.

    When I was in Shetland this year orange crocosmia/montbretia  was about the only garden plants that did grow well unless they were in very sheltered gardens.

  • Yes, they will look good in a terracotta pot - and by doing that you won't have a "thug" spreading in your garden (Verduns word not mine). If you look closely at the picture - beyond the flowers you will see the terrible state of the tarmac road - lost count of how many times it has been dug and desperately needs resurfacing.
