Howell Krascheninnikovia lanata is a species of flowering plant currently placed in the family Amaranthaceae (previously, Chenopodiaceae), known by the common names winterfat, white sage, and wintersage.

Winterfat grows in a great variety of habitats at 100–2,700 metres (330–8,860 ft) in elevation—from grassland plains and xeric scrublands to rain shadow faces of montane locations.

Krascheninnikovia lanata is a small shrub sending erect stem branches to heights between 0.5–1 metre (1.6–3.3 ft).

The stems and gray foliage are covered in woolly white hairs that age to a reddish color.

Winterfat is an important winter forage for livestock and wildlife because its evergreen leaves are high in protein, hence its common name.
