the canned ones? Or your mom made a weird casserole? (Hot Dish sorry, if you're in Minnesota). It's so different.
I haven;' tried the 3 foot long beans yet, but regular green bean cooked fresh - it';s really diferent! The canned ones are mushy and weird. They're like, okays! But REAL green bean is pretty good. They can be toothy. They can be chewy. They can be.... anything you want.
Despite the common name of "yardlong", the pods are actually only about half a yard long, so the subspecies name sesquipedalis (one-and-a-half-foot-long; 1.5 feet (0.50 yd)) is a more accurate approximation.
