Vine in New Orleans

[Caitlin]

Could someone please help me identify this vine? Any chance it could be making my dog break out in hives?

Welcome to the forum!

Has the vine ever flowered?

I just moved into the house 2 months ago, so I'm not sure if it's flowered. In the 2 month that I've been here it has not.

Greetings Caitlin, welcome to the Forums.

I concur. This is Bushkiller Vine (Causonis japonica, formerly Cayratia japonica), also known as Yabu Garashi or Sorrel Vine. This member of the Grape Family (Vitaceae) is native to southern and southeastern Asia, China, Korea, Japan, Taiwan, Hainan, Sri Lanka, Indonesia, New Guinea, Solomon Islands, New Caledonia, and Queensland. It is also a weed in several southeastern states in the U.S.
The vine has compound leaves in an unusual arrangement, greenish-yellow to orange flowers and small, black fruit.
