Edible plants to help define/mark out growing areas & paths - recommendations?

Afternoon all,

I was just wondering if there are any edible plants in which I can plant around a crop growing area which will help define that area?

Could I use chives, lavender to do this?

Any other recommendations?

Top points if it is present all year round (at least visible ) and if it is easily manageable (as to say does not get out of control).

Thank you for your help,

Samuel

I am using onions, shallots, garlic, and sweet potato vine to make borders in some places. I also use non edible support species like bulb flowers, Liriope grasses, and a few different species of spiderwort.

I have seen lavender used as a great border too. I bet chives would look neat as well, especially when flowering.
