leaves of 3......leave it be

That's what hubby says, but if I leave it be, it'll take over a corner of my yard..

Looks like hyacinth bean vine. Definitely not poison ivy.

Here is a link that might be useful:

I cuncurr with Marti. Hyacinth bean. One can eat the young beans but they get toxic as they ager.it is commonly used in semitropical areas in asia.

Oh wow that pic looks exactly like what's in my yard! DH is highly allergic o poison ivy, so we've been afraid to even approach it. Hank you so much!

Poison Ivy plants are normally slightly notched , lighter green , sometimes shiny, no purple stems. Google it and look for it.
