- Description
-
Pigweed is a multi-stemmed summer annual in the Amaranth family. Whether it is native to North Carolina or an introduced and naturalized species is debated among botanists. Considered a weed, it can be found growing in wastelands, prairies, fallow fields, farm lots, gravelly areas, and cultivated fields. It is not recommended for most gardens. Its invasiveness causes yield loss in many vegetable row crops. It grows unbranched or with minimal branches.
The seeds are edible and can be eaten raw or cooked. They are sometimes ground into a powder and eaten as a substitute for cereal. Sprouts can be added to salads. Although portions of this plant are edible, ingestion is detrimental to pigs, cattle, sheep, goats, and horses.
This variety of pigweed is different in appearance than other common weeds in the same family. However, it can be identified by its shorter and stouter growth habit. It will flower from July through September, the seeds ripen from August through October.
It is typically pollinated by the wind.
