Left alone no one notices

I saw the okra left alone in the vacant field.
It's too late to eat ...so they are still left alone their until going dead.
I wonder why they are only left but other plants were already cleaned out there.
It seems like okra plant is special among other summer vegetables.
I like the taste of them for salad or tempura.
I'd like to enjoy winter vegetables such as radish, white rape and so on.
