Leaves are unsuitable and potentially unsafe due to aromatic toxins. Seeds are excellent when cooked, easy to harvest, and traditionally significant. Watson’s goosefoot is a seed-plant, not a green, and should be treated as such. Edible Uses & Rating: Watson’s goosefoot provides edible seeds and, historically, these seeds represented the primary food value of the species. Leaves are not recommended due to their resinous compounds and strong scent, which aligns the plant with the more toxic Dysphania subgroup. Seeds, however, are nutritious, abundant, and of good quality once cooked, comparable in flavour and texture to other Chenopodium grains. This species receives a high rating for seeds and a very low rating for leaves, making it a specialised but reliable grain source for skilled foragers [2-3]. Taste, Processing & Kitchen Notes: Fresh leaves are strongly aromatic, resinous, and often unpleasant, carrying overtones reminiscent of epazote or other Dysphania species. Their bitterness and herbal intensity make them unsuitable for salads or potherbs. Seeds, by contrast, taste mild and nutty once cooked, similar to quinoa and Fremont’s or pitseed goosefoot. Toasting enhances flavour by adding a delicate roasted aroma while reducing the sharpness associated with raw resinous chaff. Boiling produces a soft grain-like porridge that pairs well with both savoury and sweet preparations. As with most chenopods, combining toasting followed by boiling produces the richest and most balanced flavour [2-3]. Seasonality (Phenology): Watson’s goosefoot germinates in late spring as soils warm. Vegetative growth follows through early summer, with flowering typically occurring mid- to late summer. Seeds mature from late summer into early autumn. Plants often persist as dried stalks with seeds well into fall, enabling extended harvesting windows. Safety & Cautions (Food Use): Like all strong-scented goosefoots and especially those formerly grouped with Dysphania, Watson’s goosefoot contains aromatic oils that may include ascaridole or related compounds. These substances can be harmful if consumed in quantity and may produce gastrointestinal or neurological symptoms. Leaves should not be eaten. Seeds are generally safe when cooked thoroughly. Avoid raw seed consumption 2-3]. Harvest & Processing Workflow: Harvest seeds once the plants turn red-brown and dry, stripping mature inflorescences into a container. Allow seeds to dry further before winnowing. Due to the plant’s resinous nature, some chaff carries strong aromas; winnowing, sieving, and rinsing can reduce these. Seeds may then be toasted, boiled, or ground into flour. Foragers typically prioritise seed-rich areas and collect multiple plants at once due to the species’ high yield. Cultivar / Selection Notes: No cultivars exist. Populations show variation in colour intensity, aroma, and seed size, but all share similar culinary and ecological characteristics. Look-Alikes & Confusion Risks: Watson’s goosefoot may resemble Dysphania graveolens or Dysphania botrys, all of which possess aromatic, resinous foliage. Unlike the mild Chenopodiums (e.g., C. album, C. berlandieri), Watson’s goosefoot is strongly scented, allowing quick distinction by smell and leaf texture. It should not be confused with the mild, powdery-leaved goosefoots preferred as leafy greens. Traditional / Indigenous Use Summary: The Navajo of Arizona are recorded as gathering Watson’s goosefoot seeds as a food resource. The species likely contributed to broader Southwestern seed-gathering traditions, particularly in regions where dependable grain crops were scarce. Leaves do not appear to have been used traditionally. Seeds, however, provided a shelf-stable, calorie-dense grain suitable for grinding into meal or cooking into porridges.

None Known

This species does not offer ornamental value in conventional landscaping but performs reliably as a pioneer species in restoration settings, contributing to soil nutrient cycling and supporting seed-eating wildlife. Ecology & Wildlife: Seeds are eaten by small mammals and granivorous birds, making the plant an important component of desert and foothill food webs. Its aromatic foliage may deter some herbivores but provides shelter for ground-dwelling insects. As a disturbance-tolerant plant, it plays a role in soil stabilisation and colonisation following erosion events.
