Hordeum jubatum
species of plant
Hordeum jubatum, with common names foxtail barley, bobtail barley, squirreltail barley, and intermediate barley, is a perennial plant species in the grass family Poaceae. It occurs wild mainly in northern North America and adjacent northeastern Siberia. However, as it escaped often from gardens it can be found worldwide in areas with temperate to warm climates, and is considered a weed in many countries. The species is a polyploid and originated via hybridization of an East Asian Hordeum species with a close but extinct relative of Californian H. brachyantherum. It is grown as an ornamental plant for its attractive inflorescences and when done flowering for its inflorescence.
Properties
Foxtail barley (Hordeum jubatum) propagates by seed. It is known for its ability to tolerate saline soils but is capable of productive growth on soil types ranging from loamy to clayey soils with pH's of 6.4 to 9.5. The upper limit of soil NaCl for productive growth and development is 1.0%. Foxtail barley is also adapted to a wide range of moisture regimes from dry to wet. Although this species is generally found on moist sites, it can withstand drought-like conditions.

Why this record matters
“Hordeum jubatum” is worth following because a concise public description often conceals a longer documentary argument. Here, Hordeum, jubatum and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 11, 2026. The linked authority identifier is Q161883. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
