Ambrosia tomentosa
Also called Burragweed, Skeleton-Leaf Burr-Ragweed, Skeletonleaf burr ragweed, Skeletonleaf bursage, Silverleaf Poverty Weed, Skeleton Leaf Bur Sage, Skeleton Leaf Bursage
A perennial weedy wildflower of the western US plains and basins, growing up to about 90 cm tall with deeply lobed leaves and spiny burs. It is a noxious weed in several states and a strong pollen allergen, so it is best left out of gardens.
Ambrosia tomentosa, the skeletonleaf bur ragweed, silverleaf povertyweed, or skeleton-leaf bursage, is a North American species of perennial plants in the family Asteraceae.
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. It is often found growing alongside roads and in the sandy parts of plains.
