I started a new perennial garden this year and did a soil test and sent it to a lab and the results came back as optimum or close to optimum in every element and was also good range in ph and organic matter and I did not add anything to it prior so it shows that native soil is indeed possible okay by it's self but that can't be said every where which amending would be needed. I live in a area with hard clay soil so amending is pretty much a must around here,
