About Wright's Cudweed (Pseudognaphalium canescens) Pseudognaphalium canescens (syn. Gnaphalium canescens) is a species of flowering plant in the Asteraceae (Sunflower) family known by the common name Wright's Cudweed. It is native to western North America from western Canada to northern Mexico. It can be found in many habitats, from mountains to plateau to coastline. The many-branched stem is erect to a maximum height of around a meter. It is gray-green and woolly with many narrow leaves.

Each woolly head is a few millimeters across and contains many tiny disc florets. This plant is seldom seen in gardens but is useful for restoration projects.
