Abstract
Curlycup gumweed (Grindelia squarrosa) (Pursh) Dunal is native to North America except in the southeastern United States. This forb (herbaceous broadleaf plant) is commonly found along roadsides, in mismanaged pastures, arid areas, idle fields, rangeland and waste areas. Learn how to identify and manage this drought-tolerant weed via prevention strategies and mechanical, cultural and herbicidal controls in this concise Idaho Green Thumb.
