Definition

Noun: 1. A troublesome weed: A prickly, bushy Eurasian plant (Salsola tragus) that has become a problematic invasive weed in regions like the central and western United States. It is known for breaking off at the base and tumbling in the wind to disperse its seeds.

Usage

Advanced Usage

• It can be used metaphorically to describe something that spreads uncontrollably or is difficult to contain.
  • The conspiracy theory spread like Russian tumbleweed across the internet.

Variants and Related Words

Synonyms
