Pseudognaphalium stramineum, commonly known as Annual Cudweed, Cottonbatting Plant, Chilean Cudweed, Cotton Cudweed, or Cottonbatting Cudweed, is an herbaceous plant that can behave as a perennial, biennial, or annual, depending on its growing conditions. It is native to arid and semi-arid regions of Western North America, where it thrives in open areas, often on disturbed ground and in coastal scrub habitats. This plant typically grows at a moderate rate to a height of 1-2 feet (0.3-0.6 meters) and a width of 1-1.5 feet (0.3-0.5 meters). Its foliage is generally grayish-green, and it produces clusters of white or cream flowers that are quite showy, blooming in the summer and fall. The flowers are composed of numerous small heads, giving the plant a fluffy, cotton-like appearance.

Pseudognaphalium stramineum is valued for its drought tolerance and the visual interest provided by its cottony flowers, which can add texture to garden compositions. It is often used in rock gardens, xeriscaping, and as a filler in borders or mixed beds. It is also occasionally used for dried flower arrangements. In cultivation, it prefers full sun to part shade and adapts well to medium or slow-draining sandy or loamy soils. While it requires medium amounts of water, it is relatively low maintenance and can tolerate periods of drought once established. There are no widely recognized cultivars of this species in the horticultural trade, and it is generally grown from seed. Gardeners should be aware that in some conditions, it can self-seed and become somewhat weedy.CC BY-SA 4.0
