I am sure they are the same species but there is much variation.The pictures ones cost $2 per bean instead of the usual $1 per bean.That one is a little over the 4 ft mark but out of the same batch there were certainly much longer and heavier ones.Maybe they don't bring the smaller ones in to the market.The seeds are not black as the picture shows being a deep maroon with some orange/yellow ones which for me helps identify this type.
