Lima bean (Phaseolus lunatus) is an important vegetable crop in Wisconsin. Acreage is limited relative to snap bean or pea, but several thousand acres are grown and processed within Wisconsin. Lima beans for processing are primarily grown in California, Wisconsin, and Delaware. Similar to snap bean, lima bean originates from Central and South America. Several lima bean types exist with small seeded, dwarf bush types being the primary processed type compared to the larger seeded, pole types. Lima beans are related to snap bean (Phaseolus vulgarus), but there are distinct differences in their growth that influences important management needs.
