• It's my first attempt at such, so it may be way too obvious or way too cryptic, but yes, I believe it meets the usual rules for a cryptic clue. I don't want to explain it yet; that would defeat the purpose. But if no-one gets it then I'll admit defeat and explain how I thought it should work. – Ben Aveling Oct 19 at 11:15

Rhubarb leaves

First, to get rhubarb:

regret quip = rue barb
stage chatter = rhubarb (actors say rhubarb rhubarb to mimic background chatter)

Second, to get leaves:

goes away = leaves
poisonous part of stage chatter (rhubarb) = the leaves of the rhubarb plant, which are poisonous

The title:

The red part of the rhubarb plant is edible, the green leaves are poisonous

And how I even figured any of this out:

I had no idea what "stage chatter" meant but when I searched online for that term, I found out that it was a crossword clue whose answer was "rhubarb". That didn't make any sense to me so I researched "rhubarb stage chatter" and found out that "rhubarb" was a word repeated by actors to produce background noise/conversation. That led me to finding out that the leaves of the rhubarb plant were poisonous, etc. I learned several new things solving this puzzle!
