Is 'ivy' a synonym of creeper/vine?

Question

Ok, I know that Creeper=Vine (the plants) but is Ivy=Creeper=Vine?

Oh, *P.S* What's the difference between Poison Ivy and 'regular' Ivy?

Answer 1

Not really.  There are a lot of vining plants that don't have the common name of ivy.

Poison ivy, Toxicodendron radicans and T. rydbergii, are relatives of sumac, mango and cashews -- they're all in the Anacardiaceae.  I'm not sure what "regular ivy" is to you, but I'll take a chance that it's English ivy, a relative of ginseng and Schefflera.  

English ivy and poison ivy don't look anything alike:
