Some hardier nigtshades don’t mind the salt air.
Tomatoes, for one.
Maybe you can create a hybrid?
Oh, wait...Homer Simpson already did.
😂😂
The only success I’ve had is with native Everglades tomatoes and a little success with upside down cherry tomatoes. Their fine and tasty, but tiny little boogers. All larger tomato varieties have failed. I’m giving 4th of July variety a go this fall. I just want some big enough for a sammich. Mind you I’m growing less than 100 yards from super salty water to the east and the west. It’s bloody harsh.
