Almost like a wait-a-minute vine, eh?
A wait-a-minute vine is ths odd looking reject from the rain forest.
Grows in the wild here in NY/NJ/PA.
It is medium green, has oval leaves, and yellow thorns slightly longer than a quarter inch, thorns tipped in red or black.
Walking by it grants one the unique feeling of thorns grabbing you and saying "Wait a minute".
That like the "wait-a-bit" tree in "The Gods Must Be Crazy?"
