Whats the difference between Butter Beans and Lima Beans?
Lima Beans (Phaseolus limensis) and Butter Beans (Phaseolus lunatus), the latter also called Sieva, Civet, or Seewee Beans. The two species are closely related and readily cross-breed; Limas are larger and more vigorous than Butterbeans, but are less heat-resistant; but the larger, thicker Lima pods are easier to shell. It is common for seed catalogues to confound the two species (referring to, for example, “Sieva lima beans”).
