Winterfat (Krascheninnikovia lanata) is an extremely hardy shrub with a woody base and many upright, slender branches bearing small blue-green leaves. The leaves remain on the plant throughout the winter until they fall off and are replaced with new growth in the spring. Although the flowers are small and inconspicuous, they give way to white hairy fruits that resemble cotton and provide winter interest, as well as an important food source for animals. Winterfat can be used in natural or restorative landscapes, as well as making an attractive addition to xeric gardens.
