Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
The edible is the plain green one. It is also called Fish Mint...because it imparts a fishy flavor to foods; check some Vietnamese recipes to see how it's used.
Not sure if the ornamental/variegated one is actually edible.
