Is there anything that looks like a raspberry but isn't?

I have some plants that looks like raspberries to me. They are very cane like and the leaves look like raspberry leaves. However, some are completely thornless and others have just a few tiny little thorns. I don't want to get my hopes up that they are an amazing thornless raspberries if they are actually some boring ugly ornamental!

I will try to post some pictures next time I can connect my phone to WiFi.
