Here is a weed I gathered the seeds from last year. It had bloomed on a Mediterranean island, Corsica, up in the mountains (around 2000 meters above see level, I believe snow covered 2-3 months pour year). I was so amazed by the strong scent of the plant that I hoped I could have it home somewhere.
Now I let it multiply in some pots of mine here, and am curious what indeed it is.
It head small opposite leaves (2-3mm), it gets kind of purple when it gets water deprived. Seedlings didn't bloom the first year. It is strong scented, about little like point, stronger and different. It could be some kind of microscopic sage, I'm curious...
