Pigweed
Pigweed
Pigweed (pronunciation: /ˈpɪɡˌwiːd/), also known as Amaranthus (pronunciation: /ˌaməˈranTHəs/), is a genus of annual or short-lived perennial plants. Some pigweed species have been reported as edible plants worldwide and have been cultivated, both for their seeds and as leaf vegetables, most notably in Mexico, where it is called quintonil.
Etymology
The term "pigweed" is derived from the fact that this plant, once cut, could be used as feed for pigs. The genus name, Amaranthus, comes from the Greek "amarantos," which means "unfading" and is an allusion to the long-lasting flowers of some species.
Related Terms
- Amaranth: A group of more than 60 different species of grains that have been cultivated for about 8,000 years. Amaranth is a close relative of pigweed.
- Quintonil: A type of edible pigweed that is commonly used in Mexican cuisine.
- Leaf vegetable: A vegetable that is eaten as a main part of the plant. Pigweed is often consumed as a leaf vegetable.
Usage
Pigweed is often considered a weed in many gardens and fields, but it is also recognized for its nutritional value. The leaves can be cooked and used as a spinach substitute, and the seeds can be used as a grain in cereals or ground into flour. Some species of pigweed, like the redroot pigweed and the rough pigweed, are known to be resistant to certain herbicides, which can make them difficult to control in agricultural settings.
Health Risks
While pigweed is edible and can be beneficial due to its high nutritional value, it can also pose health risks. Some species of pigweed, such as the Palmer amaranth, produce a large amount of pollen, which can contribute to hay fever and other allergies. Additionally, pigweed can host viruses and pests that can damage crops.
