tumbleweed amaranth, white amaranth
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.
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.
