Using birds foot trefoil for lawn on a farm (Pardee?)
Seeing trefoil surviving from a seeding of a field 8 years ago, I wondered if it could be a low maintenance lawn with a mowing couple x's a year? Area gets no foot traffic. The yellow blossoms are lovely.

Using Bird’s-foot trefoil (Lotus corniculatus L.) might not be a good choice for a lawn covering. It is considered weedy and is invasive in some areas. You might end up with it creeping into a neighbors lawn who does not like a yellow blooming lawn. Some day, if you decide you don't like it, it will be difficult to remove.
Here is a link to information about it's invasiveness.
There is a display of alternatives to lawn grasses at the botanical gardens in Ann Arbor. You might consider looking at this. http://www.lsa.umich.edu/mbg/see/MBGAlternativeLawn.asp

There are better choices than Bird’s-foot trefoil.
