Summary
Allenrolfea occidentalis is a low, shrubby halophyte of alkali flats and desert playas in the western U.S. Its succulent, jointed stems are intensely salty and sometimes bitter, forming a structural and ecological keystone in high-salinity habitats. As a human food, it is marginal: parts can be nibbled or used as a mineral-rich, salty accent, but high salt and other compounds limit safe intake. USDA Zones roughly 6–9, height usually 0.3–1 m. Picklebush was a significant staple of early Great Basin cultures, with seeds that are highly nutritious, abundant, and relatively easy to process. They can be eaten boiled, toasted, or ground into flour. Young stem tips are technically edible but very salty, so they should be consumed sparingly.
Physical Characteristics

Allenrolfea occidentalis is a SHRUB growing to 0.5 m (1ft 8in) by 0.4 m (1ft 4in) at a medium rate.
See above for USDA hardiness. It is hardy to UK zone 7 and is not frost tender. The flowers are pollinated by Wind.
It is noted for attracting wildlife.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: neutral and basic (mildly alkaline) soils and can grow in very alkaline and saline soils.
It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought.

Plant Habitats
Edible Uses
The seeds are the primary edible part and were once a staple food for Native Americans in the Great Basin. They are small, brown, and nutritious, with a mild whole-grain flavor lacking the musty character of many goosefoot relatives. Seeds mature from August to December and can be collected in large quantities by gently tapping the brittle, dried stem tips. Processing is relatively straightforward: the papery capsules crumble away and the seeds can be winnowed free. Seeds can be toasted, boiled, or ground into flour, and were traditionally made into porridges, flatbreads, or seed cakes. They remain one of the most important ancient desert grains [2-3]. The young stem tips are also edible raw or cooked, but they are extremely salty and contain oxalic acid. They should be eaten only in moderation and preferably boiled to reduce saltiness and potential irritation. Older stems become woody and unsuitable. In addition to food use, dried stem tips can be chopped and used as a salty seasoning substitute[2-3]. Seasonality (Phenology): Evergreen to semi-evergreen; fleshy growth most active in warm seasons. Flowering and seed set typically occur late summer to autumn. Harvest & Processing Workflow: If used, pinch young green tips only, blanch in fresh water, taste-test cautiously, and use strictly as a garnish/condiment, never a bulk vegetable. Look-Alikes & Confusion Risks: May be confused with glassworts/samphires (Salicornia, Sarcocornia), which are more commonly eaten but share similar salt issues. Accurate ID helps track ecological vs culinary expectations. Traditional/Indigenous Use Summary: Better documented as a fuel, habitat, and landscape plant; any consumption was likely minor and situational.

Other Uses
An ecological specialist and restoration asset. Forms compact, durable shrubs, excellent for extreme-salinity reclamation. Traditional/Indigenous Use Summary: Better documented as a fuel, habitat, and landscape plant; any consumption was likely minor and situational. Ecology & Wildlife: Provides cover and structure for small mammals and birds on otherwise barren flats. Its seeds and associated invertebrates offer food resources. It contributes to salt and water table dynamics. Pollination is likely largely wind-mediated, with minor insect visitation.

Cultivation details
Identification & Habit: Iodinebush forms rounded, intricately branched shrubs with fleshy, jointed, cylindrical green stems that become woody and gray with age. Leaves are minute and scale-like, quickly shed; photosynthesis is mainly via stems. The overall look is of a dense, coral-like mound on alkali soils. Flowers are tiny, inconspicuous, borne in the joints or spike-like arrangements along stems. The plant often forms nearly pure stands on saline bottoms. Growing Conditions: Obligate halophyte thriving on saline-alkaline flats, playas, and desert basins with high pH, salt crusts, periodic flooding, and intense sun. It is highly drought-tolerant once established. Habitat & Range: Widespread in arid western North America, especially the Great Basin, Mojave, and Sonoran regions, on strongly saline/alkaline soils where few other shrubs thrive. Size & Landscape Performance: Forms compact, durable shrubs, excellent for extreme-salinity reclamation. In ordinary garden soils without salt it may perform poorly or be outcompeted. Cultivation (Horticulture): Rarely cultivated except for restoration or research. Requires saline, well-drained soils and full sun. Overly benign soils reduce its competitive advantage. Pests & Problems: Extremely hardy against drought, salt, and herbivory; main threats are hydrological alteration and disturbance of alkali habitats. Cultivar/Selection Notes: None.

Please note that a plant may be invasive in one area but may not in your area so it's worth checking.
Low beyond its specialized niche. Where conditions suit it, it is a dominant native halophyte, not typically an invasive exotic.
