A tangle of cleavers

There are four crops in the fields immediately adjacent to us - potatoes, fodder beet, wheat and oats. They also grow lots of rape but none close by this year. Last year they grew triticale in the field next to us - this is a hybrid of wheat and rye and was first grown in laboratories in the late 19th century (would that be early genetic engineering?).
Having been here for 7 years now I am getting better at crop identification and fnd the whole process of maximising yield very interesting but am also saddened at the impact it has on the wildlife. For example when I moved here we would regularly see barn owls hunting the strips of land at the edges. Now they farm so close to the edges that the habitat has been lost and with it the barn owls. I would love to know how much additional revenue this practice generates ....
Anyhow I digress. At the edges of the field you can find plants that escape the crop sprayers (another discussion point!) and the name of this one (Galium aparine) will depend on where you live - cleavers, stickybud, beggar lice, clithe, cliders, goose-grass, goosebill, hariff and catchweed are a few.
The roasted seeds are said to be an excellent substitute for coffee but as cleavers also has medicinal uses as a laxative and emetic, consumption should be in moderation!
Oh - and the crop is oats.
