Ambrosia tomentosa, the skeletonleaf bur ragweed,[3] silverleaf povertyweed, or skeleton-leaf bursage,[4][5][6] is a North American species of perennial plants in the family Asteraceae.[7]
Skeletonleaf bur ragweed is native to the west-central part of the United States, primarily the western Great Plains, the Colorado Plateau, and eastern Great Basin.[8][9] It is often found growing alongside roads and in the sandy parts of plains.[10]
It is considered a noxious weed in several states.[6][11][12] It is also considered a severe allergen.[13]
Description
[edit]Ambrosia tomentosa grows up to 3 feet (91 cm) tall. The deeply lobed hairy leaves grow to 5 inches (12.7 cm) and have toothed margins. Flowers are small and yellow and produce spined 2-seeded burrs. In addition to seeds it can also reproduce via its widely spreading roots.[14][7]
