This is a bush we bought a few years ago. It has no flowers but it does provide a nice red/purple color to our front walk. I have no idea if it's ok to trim it. It does have thorns!!! I'm going to have to trim it back some, it's getting pretty wild.
Here it is a few months ago. It dies back to nothing but sticks. Blucky!
My hand is MUCH better today. Today, my elbow hurts where I slammed it into the wall. And I have a really pretty bruise on my leg where I hit the laundry basket (that hit the chair & wouldn't move, causing a bruise. I'm not THAT delicate!)
