are they the vine or the shrub?

I'm sorry, I responded to this but apparently didn't hit the confirm button like I thought I had - mine didn't do too well last year, so they never got big enough for me to tell. My neighbor calls it a "vine" but his grows into a huge mound, about six feet wide and four feet high. Since he was calling it a vine, I asked him if he trained it into a mound, but by his answer I could tell he didn't know what I meant. So, it if it is a vine, it's apparently very trainable. Does this help at all?
