Though not a groundcover or interplanting candidate, vetiver grass can handle the pH and can provide a close by, perennial and very valuable source of chop and drop mulch/compost material. Its columnar root system won't compete with the blueberries, and it can provide a host of other benefits depending on your situation. Might be good edging for uphill on contour water infiltration?
Why is the vetiver grass not a candidate for a ground cover? Too much competition for nutrients?
