ANYWAY... there is no edging separating the flowers from the little strip of lawn there, so the grass tends to grow in and wild violets and ground ivy. Since I can't mow that strip with the flowers, the grass gets tall. In the past I would have worked and worked digging every bit of grass and weed out and then laying down a bunch of mulch, in the service of the ideal of neatness and a manicured look.
This year, since I decided I want green mulch for my veggie beds, I looked at all that tall grass and weeds and went "green mulch!" I ripped it out by hand, being careful to leave some, so that it could grow back and grow more mulch for me!
Didn't mulch it (because I want it to grow back) and left some here and there so it's not manicured looking this time, but still looks fine... there's flowers and there's green, what more do you need!
... and the light dawns! 
You'll be sowing seeds of particular dynamic accumulators/green mulch you want to grow there next!
