This plant is a small annual amaranth that can be found in disturbed areas such as abandoned fields, roadways and streams.Often this plant has stems that arch upwards in some way that when combined together form a spherical cup-like apperance.

Interesting facts

This plant is also known as the tumbleweed. Its a sign of the american west and is often depicted in artistic renditions of the region.

The very small flower clusters that one finds on the plant are actually either a male of female flower. Both are borne seperately on the same plant in the axils of the leaves. The flowers are green and surrounded by tiny, sharp-pointed bracts.
