The term "butter bean" is widely used in North and South Carolina for a large, flat and yellow/white variety of lima bean ("P. lunatus" var. "macrocarpus", or "P. limensis"). In the United States Sieva-type beans are traditionally called butter beans, also otherwise known as the Dixie or Henderson type. In that area, Lima beans and butter beans are seen as two distinct types of beans, although scientifically they are the same. In the United Kingdom and the United States, "butter beans" refers to either dried beans which can be purchased to rehydrate, or the canned variety which are ready to use. In culinary use there, lima beans and butter beans are distinct, the latter being large and yellow, the former small and green. In areas where both are considered to be lima beans, the green variety may be labelled as "baby" (and less commonly "junior") limas.
