Tumbleweeds!

What are they and where do they come from?
TUMBLEWEEDS are native to Ural mountains of Russia. First noted in the late 1800s, they are now found all over the west. They were likely brought in with Russian farmers who settled that region. While tumbleweeds roll they can spread up to 250,000 seeds from one plant. tumble weed snowman jpg Tumbleweeds!

Are tumbleweeds good for anything? Some people spray paint them and stack them as desert snowman. During the dust bowl days of the Depression, immature tumbleweeds were used as an emergency food to feed both livestock and humans alike. They also inspired the rolling robots in Star Wars movies. Researchers have discovered that they can pull depleted uranium from contaminated soils of battlefields. Tumbleweeds also inspired the early NASA landing system for a Mars Rover that bounced and rolled as part of its landing. And everybody knows the song that goes “rolling along with the tumblin’ tumbleweeds.”

Researchers are working hard at finding natural controls for tumbleweeds through the release of beneficial insects and diseases that attack the plant in a young stage.
