I do not have land (yet), but I am fascinated by birdsfoot trefoil as an alternative to a grass lawn. Like so many area, we here in Quebec are suffering from a really nasty drought and all of the lawns have died. Meanwhile, the birdsfoot trefoil is doing fine. My uncle has it on his farm and it is one of the few plants that is still growing. I think it would make for a nice alternative to grass. It doesn't grow more than 20 cm high is the best conditions, and really wouldn't require any mowing, fertilizing etc., which seems more ecological, less time consuming and SO much prettier than grass. If I did have land, I would plant this stuff and feed it to my rabbits; they love the stuff!
