bunch grass
LowTechnical / Scientific
Definition
Meaning
A type of grass that grows in dense tufts or clumps rather than forming a continuous sod.
Used primarily in botany, ecology, agriculture, and landscaping to refer to perennial grasses that grow in discrete clusters, often found in arid or semi-arid regions like prairies, steppes, and certain savannas. They are important for soil stabilization and as forage.
Linguistics
Semantic Notes
The term is a compound noun that specifically denotes a growth habit (clumping) rather than a single botanical taxon. It contrasts with 'sod-forming' or 'rhizomatous' grasses. Sometimes used more loosely in gardening.
Dialectal Variation
British vs American Usage
Differences
The term is used in both varieties but is far more common in American English due to the prevalence of such grasses in North American prairies and rangelands. In the UK, it might be encountered in botanical or ecological contexts.
Connotations
In American English, it often carries connotations of the Western landscape, drylands, and native ecosystems. In British English, it is a more neutral botanical descriptor.
Frequency
Substantially higher frequency in American English.

Common Mistakes
- Using 'bunch grass' to refer to any wild grass. Confusing it with 'brush grass' or 'brush'. Treating it as a plural noun (e.g., 'bunch grasses' is correct for multiple species).

Frequently Asked Questions
It is most commonly written as two words ('bunch grass'), though the hyphenated form 'bunch-grass' and the closed form 'bunchgrass' are also accepted, especially in American technical writing.
Typically not. Bunch grasses grow in separate clumps, leaving bare ground between them, which is not ideal for a uniform lawn. They are used in ornamental 'meadow' or 'natural' landscaping.
'Ornamental grass' is a broader horticultural category for grasses grown for beauty; many ornamental grasses are bunch grasses, but not all (some are spreading). 'Bunch grass' is a term describing growth habit, not aesthetics.
Yes, examples include Blue Grama and Buffalo Grass in North American prairies, and species of Festuca and Nassella used in gardening worldwide.
