Anyway I am happy to allow this goose grass to rub shoulders with the more exotic Iris ensata
014 by charliepridham, on FlickrSo far this has not committed the sin that gets most weeds labeled as such, which is not to know its place and this seems happy to just grow in the pond. I have in parts of the garden regular goose grass thanks to the inheritance of 5 Persian cats when my FIL died (now thankfully all gone) the long coats got covered in the seeds which they then spread all over the garden.
Not sure what spreads convolvulus seeds but that seems a very effective system and I never truly get rid of it .
Yesterday a garden visitor cheered me up " How do you get rid of Horsetail" Yipee thats one I don't have was my first thought!!
