Pigweed, Slender/ Green Amaranth

Amaranthus hybridus
This 2-6' plant may have a purplish stem. The alternate leaves are lance-shaped to elliptical and are smooth-edged. The nondescript, greenish to reddish flowers have no petals and are in slender, cylindrical spikes from the leaf axils. The flowers are interspersed with long bristle-like bracts much longer than the flowers. Blooms August-October in waste ground, roadsides, near cultivated areas.

The flower spikes are longer, thinner and more spreading than those of Rough pigweed (A. retroflexus).
