Acidic Concoction Pathfinder

Acidic Concoction can trigger an acidic burst on a poisoned target, consuming the poison and applying an AOE life loss damage based on 1.5x of the total damage it would have dealt for the entire duration.

The gem doesn't especially say "poisoned enemy," just a poison target. This means it will work on plants that can be poisoned by the poison burst arrow, and the advantage here is that once the plant are poisoned, they don't go away;
allowing you constantly reapply the AOE acidic burst without having to poison the enemy again.

Each projectile can also trigger each vine individually, allowing you to shotgun your damage if you scale the number of vines and flask projectiles.

Vine plants can only ever have one poison stack, so we are focusing on scaling the poison damage with 1 stack only and avoiding nodes with heavy downsides that give you extra poison stacks.
