Are all yellow beans wax beans?
I have come across many retail seed sources that use the term (yellow bean) in some descriptions and (wax bean) in other descriptions. I was wondering if there is a difference, if the terms are interchangeable, or maybe they are simply not being consistent when writing their descriptions. This got me to thinking about the whole yellow bean classification.
I have come across yellow variants of bean types such as Romano, Greasy, French Filet, Yellow Bush Snap (as opposed to Bush Wax), Yellow Pole Snap (as opposed to Pole Wax) beans, etc. that I assume are not classified as wax beans. But if I were to go by the definitions I have found via internet search then all those yellow variants I listed previously are wax beans. I find this hard to believe when one compares some of these beans (like Yellow Romano and Yellow Greasy) to classic wax beans like Cherokee, Pencil Pod, etc. Different flavors, textures, appearances, etc.
If there are different types of yellow beans then how does one know when a certain yellow bean should be in the category of a yellow variant of a type or in the category of wax beans? Some would be easy, such as specifying a Yellow Greasy as opposed to a Wax Greasy (which I have never heard of). Others could be a bit more difficult to classify.
I am working on a comprehensive listing of types, varieties, and strains and have found this to be very confusing. Any clarification would be much appreciated. Thanks in advance.
