I moved into my little farm in Social Circle last July. I am excited about getting some gardens going. First I have some thorn/bush vines on my fence that had berries last year. They first look like raspberries then turn black-does anyone know what they are? Some type of wild blackberry? Pretty white blooms with a pink blush to them...
Can I make jam with them? My 5 acre fence is at least half covered in them.....
