Common Names for Butter Beans
Butter beans are most widely sold as lima beans in the United States and known as sieva beans in parts of Latin America and the southern U.S. The name butter bean is often used for larger, mature lima beans (Phaseolus lunatus), though regional usage varies by market and variety. Understanding these names helps shoppers find the right beans and compare products across recipes.
Key Varieties and Names
Several botanical and market names refer to beans in the butter bean group. Though usage differs by region, the most common include:
- Lima beans
- Sieva beans
- Phaseolus lunatus
- Butter bean (market name)
Lima Beans
Lima beans are the most common U.S. name for the same beans called butter beans in many recipes. Large-seeded varieties are often labeled as butter beans at markets and stores, while smaller types may appear as baby limas or sieva beans. These terms refer to the same species but can differ in size and texture.
Sieva Beans
Used historically in the southeastern U.S. and parts of Latin America, sieva beans describe smaller, earlier varieties of Phaseolus lunatus. The name is less common in modern retail but appears in heirloom and traditional recipes. Some producers still use sieva to distinguish regional landraces.
Botanical and Market Terms
Phaseolus lunatus is the scientific name for all true butter and lima beans. When shopping, butter beans may be labeled according to size or maturity, such as large butter beans, baby limas, or dried sieva beans. Clear labeling is not always consistent, so cross-checking names helps ensure the correct product.
Factual Comparison of Names
The table below summarizes how these terms typically differ in use and context. Variations depend on region, seed size, and whether the beans are sold fresh, dried, or canned.
| Name | Typical Use | Common Regions | Notes |
|---|---|---|---|
| Butter bean | Recipe ingredient, market name | U.S., U.K., informal use | Often refers to large, mature lima beans |
| Lima bean | Retail and recipe standard | U.S., Canada, global trade | Covers large and small types, fresh or dried |
| Sieva bean | Traditional and heirloom use | Southern U.S., Latin America | Historically small, early-maturing varieties |
| Phaseolus lunatus | Scientific classification | Botanical references | Includes both butter and lima types |
Practical Tips for Identifying Butter Beans
When shopping, check packaging for details such as size, whether they are baby limas, or if labeled as butter beans. Look for descriptors like large or small, and ask produce staff if you are unsure. Fresh butter beans may be sold in pods; frozen and canned products commonly use the name lima or butter bean.
Culinary Uses and Substitutions
In recipes, butter beans and lima beans can generally be used interchangeably. Sieva beans may cook more quickly due to their smaller size, so adjust cooking times as needed. If a recipe calls for butter beans and you have limas, the dish will usually turn out the same, particularly in soups, stews, and casseroles.
Storage and Handling
Dried beans keep in a cool, dry place for long periods. Canned butter or lima beans last months past the printed date when stored in a dry pantry and should be rinsed before use to reduce sodium. Once cooked, beans stay safe in the refrigerator for about 3–4 days or can be frozen for several months.
Summary of Key Points
Butter beans may be called lima beans, sieva beans, or labeled by size and maturity. These names often refer to the same species, Phaseolus lunatus, with regional and market differences shaping which term is used. Knowing these variations helps you choose the right beans at the store and follow recipes accurately.
