Huauzontle, Nuttall's goosefoot
Chenopodium nuttalliae
Family: Chenopodiaceae
What it is like
Chenopodium nuttalliae is a ANNUAL growing to 0.6 m (2ft). It is in flower from July to October, and the seeds ripen from August to October. The species is hermaphrodite (has both male and female organs) and is pollinated by Wind. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers moist soil.
Height (m): 0.6

How it is used
Food
Rating: 4
Leaves - cooked. A mild flavoured spinach substitute. The raw leaves should only be eaten in small quantities, see the notes above on toxicity. Flower clusters - cooked. Used like broccoli, they are considered a gourmet food. Seed - cooked. A mild flavour, it can be used as a staple food. It can be used in all the ways that rice is used, either as a sweet or as a savoury dish. The seed should be soaked in water overnight and then thoroughly rinsed to wash off the bitter tasting saponins. Very nutritious and sustaining. The seed is fairly small but is easy to harvest.
Seed: includes nuts, cereals, peas and beans.

How it is grown
An easily grown plant, succeeding in most soils but disliking shade. It prefers a moderately fertile soil. Huauzontle was formerly commonly cultivated in Mexico for its edible seed and flowering shoots. It is potentially a very productive crop. Although it is said to require a fairly long growing season in order to crop well, plants grown in Cornwall in the cool wet summer of 1992 did very well. Even with all the rain at the end of the summer a reasonable crop was harvested in September. This species is closely related to quinoa, C. quinoa, and both might have originated from the same wild species. Whilst that species has been widely cultivated as a seed crop, though, this species was grown more for its edible flowering stem. Some modern works now see this species as no more than a sub-species of C. berlandieri.
Propagating it: Seed - sow spring in situ. Germination is normally very rapid, but be careful not to weed out the seedlings because they look rather like the garden weed fat hen (C. album).

Things to keep in mind
The leaves and seeds of all members of this genus are more or less edible. However, many of the species in this genus contain saponins, though usually in quantities too small to do any harm. Although toxic, saponins are poorly absorbed by the body and most pass straight through without any problem. They are also broken down to a large extent in the cooking process. Saponins are found in many foods, such as some beans. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish. The plants also contain some oxalic acid, which in large quantities can lock up some of the nutrients in the food. However, even considering this, they are very nutritious vegetables in reasonable quantities. Cooking the plants will reduce their content of oxalic acid. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition.
