Antennaria dioica (mountain everlasting,[3] stoloniferous pussytoes,[4] catsfoot or cudweed) is a Eurasian species of flowering plant in the family Asteraceae.

The plant's common name is derived from the flower clusters which are thought to resemble the pads or toes of a cat's paw.

The species name, dioica, is derived from Greek as reference to the separate male and female plants.

[8] While not widely used in herbal medicine, the plant was believed to have antitussive, astringent, diuretic and emollient properties.

[11] John Gerard's Herball (1597) describes the plant: "When the flower hath long flourished and is waxen old, then comes there in the middest of the floure a certain brown yellow thrumme, such as is in the middest of the daisie, which floure being gathered when it is young may be kept in such manner (I meane in such freshness and well-liking) by the space of a whole year after in your chest or elsewhere, wherefore our English women have called it 'Live Long,' or 'Live-for ever,' which name doth aptly answer this effects.
