I live 13 miles from Orland and my parents live there as I was raised there and I have never heard of it. I will check with my Mother today.

I don't know anything about "Mother's Nature Carpet", but you can get starter plants (liner size) of low bush blueberries, cranberries, bearberry, etc. by the flat from Western Maine Nurseries and put them in that way if you are interested. I've had great success with their plants as an inexpensive way to plant large areas. You have to buy either $100 or two flats. (I'm not associated with the company in any way, just a happy customer.)
