It's much better to establish patches of several plants grouped together. This creates an area of disturbance and mulch large enough to not be so quickly overwhelmed by the surrounding wild plants and their roots.
In any one area (say a minimum of 3-4m2) don't try to mix more than a few different perennial/ground cover species.
If you do, then what is likely to happen is that because there are very small areas of individual species, some of these will get swamped by other species unless you put in a lot of effort to prevent it. - Martin Crawford
