Are there any legumes or clovers that I could incorporate into a low
maintenance yard? I have purchased a couple of short, relatively slow
growing fescue varieties, but a legume would add some nitrogen
naturally. I was thinking about white dutch clover, but then I seemed
to recall seeing some really short yellow flowers in a yard that
appeared to be a clover, vetch or something in the legume family. It
was only about half the height of dutch clover, but I can't seem to
find any seed. (probably because I don't know the name to search for)

Most people don't want clover in their lawns because of appearance.

If the lawn has sufficient nitrogen it will get thick enough
to crowd out the clover.
