cudweeds

Cudweeds are a group of herbaceous plants belonging to the genus Gnaphalium, part of the Asteraceae family. These plants are often characterized by their woolly or cottony appearance, which gives them their common name. This dense covering of hairs helps protect them from drought and frost. Cudweeds are found in temperate regions worldwide and are often considered weeds, particularly in agricultural settings or disturbed ground.

The leaves of cudweeds are typically simple and arranged alternately on the stem. The flowers are small and inconspicuous, often grouped into clusters. They are usually white, greenish, or yellowish. Many species of Gnaphalium are annuals, though some can be biennials or perennials. They reproduce primarily by seed, which are often dispersed by wind.

Historically, some cudweed species have been used in traditional medicine for various ailments, though scientific evidence supporting these uses is often limited. The plants are generally not considered to have significant economic value, beyond their status as a common weed in many areas. Their widespread distribution and resilience contribute to their success in diverse habitats, from grasslands to roadsides.
