Grass substitutes?

I am going to ditch my lawn as I just can't keep on top of it - it is all fast growing species and between work/weather/my back and joints (and when I do get it done, it is intensely painful for me), I can only keep it short for 2-3 weeks before everything conspires to stop me mowing and it gets out of hand again.

I've been looking at different options and I'd like to do a microclover/daisy mix, possibly with something else like small plantain. Has anyone had any experience of doing this sort of mix, or of a microclover-only lawn? The less mowing the better for me!
