I want some sort of low ground cover that can be used over a whole yard
where I do not have other
plants and does not need mowing at all. Oxalis ("false shamrock") looks
promising, but descriptions
also say that it is "non-invasive", and I want something that WILL be
invasive to my whole yard, to
the exclusion of "normal" grass. Anyone have any tips?

Where do you live?
