Tumbleweed

A tumbleweed is a dry, round plant that rolls across the ground when blown by the wind. The "tumbleweed" mentioned in Psalm 83:13 and Isaiah 17:13 likely refer to the Palestinian tumbleweed (Gundelia tournefortii). This plant belongs to the thistle family. It is a prickly herb that contains a milky juice. When it dries, it breaks off and rolls across the land, often gathering in large piles in low areas.
