Common Name: cudweed
Species: Gnaphalium, Pseudognaphalium, & Gamochaeta spp. 
Bayer Code: GNAXX

The cudweeds are comprised of many different species that are similar in growth habits and control measures. In general, the cudweeds have basal rosettes and the leaves and seedheads are covered in distinct fine, white "wooly" fibers. Some cudweeds only have this hair on the undersides of the leaves, and other cudweeds have this hair on all surfaces. Cudweeds overwinter as small basal rosettes, but in the spring usually grow an upright stem.
