Yes, I see now. That narrow band of stones alongside the flagstones looks light grey in the first picture and black in the second. (I don't like it much in either picture). OTOH, the flagstones look a warm variegated brown/fawn/grew in the first picture and light silvery grey in the second.
A few nice big lumpy grey rocks would relive the rigidity of all those ruler-straight lines.
I wish I could draw a diagram, but I'll just have to do my best with words.
Along the edge of the flagstones, or right
on the edge, put three big planters - cement, light-coloured marble, tufa - anything that resembles one of the true colours in the flagstone and
isn't square. Don't measure the distance between them - just wherever they're pleasing. Then, next to each, put another planter of a different shape or height, but the same kind of colour, on the crushed stone. And another one on the flagstone. Next to one of these triads, either side, put a funny-looking rock. (Or not, if you used them someplace else. A gargoyle. A birdbath. It doesn't matter.)
Next to another one, put a little column with a small planter on it. Leave the third one alone. Then put all kinds of different plants - bushy and tall, fluffy and flowering, trailing and sword-leaved - in the planters. See what I mean? Just break up the straight edge and add visual interest, but keep the elegance of the flagstone.
The chips will be fine; they'll weather and blend in better over time. I think they look a lot friendlier than stone, and I'm sure they're easier on Fido's tootsies.
