An Eco-lawn composition for the southern climates hasn't been tested widely- though there are hints that perennial peanut groundcover could be in the mix with grasses. It seems that in Washington and Oregon there are plenty of nurseries that sell Eco-lawn seed mixes, but what about other parts of the country? Eco-Lawns are also popular internationally, but more for sports field use, information on tested plots for yard areas used in public spaces outside of the US would be interesting.
