I planted several raspberry/blackberry bushes about 4-5 years ago which quickly became inadvertent lawnmower food. I thought they were gone. Is this them or some other berry bush? Fruits are red on the bush and mature to a dark purple/black. 3 photos attached- first, the berry itself in my hand - second, A pic of one of its leaves up close - third, a landscape pic with Red fruiting berry locations circled in yellow. Thanks in advance!
