From our Catechesis of the Good Shepherd discussion about "I am the Vine, you are the branches" we wanted to understand the difference (botany classification maybe) of vines vs. ivy.

I'm thinking not all vines are true vines, even if they have the name in the title? But the ones I can think of:

grape vine (this is probably the example Jesus was using, as He was walking through a vineyard).

Wisteria vine

Trumpet vine

I'm trying to see if there is a structural difference to ivy and vines...I visually see it, but I'm wondering if there is a category. My initial searches aren't pulling up anything except Ivy and Vines in Wikipedia.

Technically, ivy is a certain type of vine. Vine describes a certain growth pattern--trailing or climbing--which is present in several plant families.
But in some areas the word "ivy" is used in a vernacular way to mean vine. That might be where the confusion comes from.

Good explanation, Theresa. That is what I was thinking it was, but wouldn't have been able to explain as well.

EDITED: I believe the ivy all have the scientific name Araliaceae. Several genus of ivy (those named Hedera) are vines. But some plants in the ivy family are trees, shrubs, or herbaceous plants (what we typically think of as a plant - annuals, perennials).

And there are plants that have a common name that includes the word "ivy" that really aren't in the ivy family - like poison ivy.

Found a definition that might help. Vines are weak-stemmed plants that depend on other plants for support. Because vines do not have to expend resources to produce structurally strong stems, they can grow extremely rapidly. They may also use rocks, soil or other things in the environment for support.

I missed your update until now, Mary.

So, some ivy fits into the vines, but not all vines are ivy? I guess I don't see that grapevines fit into the classification.

I was comparing araliaceae/ to rhamnales and not seeing the connection.

Is there a good site I should be using?
