Amaranthus retroflexus Seeds | Redroot Pigweed
LATIN NAME: Amaranthus retroflexus
COMMON NAME: Redroot Pigweed
Plant Profile
Amaranthus retroflexus, commonly known as Redroot Pigweed, is a species with a long record in gardens. Bees find the flowers quickly, and that pollinator traffic is a garden benefit in its own right. Gardeners value it precisely for this blend of qualities.
Science & Biotechnology
Within the Amaranthus group, Amaranthus retroflexus is of continuing interest to researchers working on plant diversity, seed biology and the selection of improved garden forms. Its seeds, notably rich in protein, have also drawn some nutritional research interest similar to that given to its cultivated grain amaranth relatives. It is the kind of species that plant scientists reach for when they need reliable material for propagation and selection studies.
Uses & Benefits
Redroot Pigweed works well in borders, containers and dedicated beds. Redroot pigweed’s young leaves are edible and have traditionally been eaten as a cooked green in various culinary traditions, and its abundant small seeds can be harvested and used much like grain from cultivated amaranth species. In agricultural settings, however, it is more often managed as a competitive weed, since its fast growth and prolific seed production can significantly affect crop yields if left uncontrolled. Given the right start, it carries on with minimal intervention.
Amaranth is a dual-purpose plant: the grain-like seeds are a complete protein food rich in lysine, and the leaves are a nutritious green eaten across the tropics. Folk medicine has long used the plant as a mild astringent.
Growing from Seed
Redroot Pigweed is one of those generous plants that come along well from seed. Sow fine seed onto surface of a loose, well-drained mix without covering it deeply, keeping conditions warm and consistently moist. Full sun suits this vigorous, fast-establishing annual well, and it typically does well, true to its reputation as one of the most successful and widely naturalised amaranth species worldwide. Sow the seeds evenly over the surface and cover lightly in a loose, well-drained seed compost, keep the sowing evenly moist, and give the pot or tray full sun. Once the seedlings have made true leaves, pot them on individually and plant out when they are sturdy and conditions are right.
Our Take
Redroot Pigweed has real presence in the garden without demanding much in return. The essentials are simple: full sun, drainage and patience while it establishes.
