Types of English Ivy?

I have recently bought what appears to be two different types of English Ivy... one is short, or "low lying", and one is taller and has larger darker leaves. The labels at the store both say English Ivy but they look different. I would prefer to grow the one that climbs buildings and does not have flowers. Do you know the difference or are these the same? Thanks.

Without seeing them, it is kind of hard to tell what they are. Here are a few ivy links that may help you though. It looks like the Boston Ivy may be the one that sticks to buildings. The other two appear to be used for ground cover. The leaf shape is very similar.
