We just moved to a very dry area of Oahu. I have found wonderful plants for my beds and have successfully started and harvested veggies. I am having a hard time finding a lawn cover. I want to eschew grass. I would prefer an option that is green. Flowers little to none. Can handle foot traffic. Can grow in partial shade and drier soil. Would prefer a non invasive species but will give on this for the others. I appreciate any input. We are from New England. I thought growing in rock was hard. I never considered lava rock. :0 I really have my work cut out for me.
