yard-long bean
Low (specialised culinary/botanical term)Informal to neutral, primarily used in culinary, gardening, and agricultural contexts.
Definition
Meaning
a long, slender legume (Vigna unguiculata subsp. sesquipedalis) that typically grows 30–75 cm (1–2.5 ft) in length, also known as asparagus bean, Chinese long bean, or snake bean.
A staple vegetable in many Asian cuisines, valued for its crisp texture and mild, slightly sweet flavour when cooked. It is distinct from common green beans due to its extraordinary length and thinner pod.
Linguistics
Semantic Notes
The term is descriptive and often used interchangeably with regional names. It's a compound noun where 'yard-long' is a hyperbolic but common descriptor of its length (it rarely reaches a full yard/three feet).
Dialectal Variation
British vs American Usage
Differences

Connotations
In both varieties, it connotes Asian cuisine, home gardening, and specialty produce. No significant difference in connotation.
Frequency
Low frequency in general discourse but higher in specific contexts like farmers' markets, Asian grocery stores, and gardening forums.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'yard' literally as двор. It is a unit of measurement. The direct translation 'боб длиной в ярд' is descriptive but not the standard term. The common Russian name is 'спаржевая фасоль' or 'длинная китайская фасоль'.
Common Mistakes
- Calling it a 'green bean' (which is Phaseolus vulgaris).
- Hyphenation errors: writing 'yard long bean' instead of 'yard-long bean'.
- Assuming it is always exactly one yard/three feet long.

FAQ
Frequently Asked Questions
Not usually. The name is somewhat hyperbolic. They typically grow between 30 to 75 cm (1 to 2.5 feet). A 'yard' is 91 cm, so some pods may approach that length under ideal conditions.
Yes, in a pinch, but the texture and cooking time will differ. Yard-long beans are firmer, less juicy, and hold their shape better in long-cooked dishes like stews. For stir-fries, green beans may become soggy faster.
Wrap them loosely in a paper towel, place them in a perforated plastic bag, and store in the refrigerator's crisper drawer. They are best used within 3-5 days.
Generally, no. Young, fresh yard-long beans have very tender pods without the tough string found on some older common bean varieties. Just trim the stem end.
