Hello, I have common barberry bushes in my front yard, they have been here since my house was built... There are two holes due to a coal truck bringing in coal to our house... (We now have electric heat) we have tried everything to get then to grown and fill the holes, we have used fresh clippings in rooting hormones and that didn't work, we have some areas growing but not where we want them... And no one in our area sells the green common barberry because it is common... Wondering if there are any ideas on how to help fill the holes. If we buy a purple or light green barberry would it transition into the color we need? And would it fill the holes
