Tumbling Pigweed

Tumbling Pigweed

Tumbling Pigweed Amaranthus retroflexus is a common weed in North America that can grow to a height of two metres. Separate male and female flowers are clustered at the top of the stem. It is one of the plants that are known as Tumbleweeds because when it is dying down the stem breaks and the whole plant is bowled along by the wind. This is an efficient way of scattering the seeds.
