I have a small wild patch (I know a fair percentage of my garden could appear to fall into this category), where a 'weed' has taken hold. I don't mind it here - though it does like to roam around the rest of the garden too! It has nettilish leaves, which to be not too polite about it, absolutely stink! Something between rich armpit and fungussy foot might describe it vaguely. The square stems are hairy, and the root system fairly shallow - it is by underground means that it spreads. Much as I feel it likes my garden rather more than I like it, I can live with it's presence. It is not too unsightly, just a bit pongy when rubbed. I have a faint suspicion it may be related to something - not sage, but something with parroty - beaked flowers, of whose name escapes me! Here is a pic or two to help: All ideas appreciated!
Jarbax, it is a Lamium (dead nettle). Here is a link to check it against - http://en.wikipedia.org/wiki/Lamium Click on the Deutsch language as the pics are much better. We have it in white, but I've never had a sniff of it - and don't know if I will now that you said what yours smells like!
It looks quite attractive like that Jarbax. I have it in my garden but I am not sure what the flowers are like because I pull it out every time I see it, The runners are a nuisance, and as you say it has a very distinctive smell. Its a typical member of the mint family; square stalk, opposite leaves and aromatic (if thats the word!). It's related to Mentha (mint), Salvia (sage) and Nepeta (catmint).
