I hummus, therefore I am ...
Sorry, no pic as of yet but trying to find the name of a plant type I spotted yesterday where the stem is massive and looks a little bit in shape and form like ginger? (light brown, bulbous stem, etc.) ... and just with green leaves on top of that. I realise I'm shit at explaining this, but it really bugs me because I Must Know... (!)
But do you mean there are rhizomes on the surface ?
If the leaves are spiky it might be an iris.
