Antennaria howellii (everlasting or Howell's pussytoes)[3][4] is a North American species in the genus Antennaria within the family Asteraceae. It is native to northern Alaska, much of Canada including the Arctic territories, and the northern United States as far south as northern California, Colorado and North Carolina.[5]
Antennaria howellii is an evergreen perennial plant. The form is usually basal rosettes, largely clonally propagated. The basal rosette leaves are 2–4 cm long and 6–12 mm broad, light green and spatulate, with a thin arm and a broad tip with a point. They have woolly white undersides. The flowerheads appear in May, on a stem 15–35 cm tall with smaller, slender leaves 1–4 cm long. It is commonly seen growing under pine stands.[3]
The plant is named for American botanist Thomas J. Howell, who collected the first known specimens of the plant in 1887.[6]
The petaloidea subspecies is listed as a special concern and believed extirpated in Connecticut.[7]
The Nuxalk Nation take a decoction of leaves for body pain, but not pain in the limbs.[8] The Ojibwe take an infusion of the neodioica subspecies after childbirth to purge afterbirth and to heal.[9]

Cette vivace à feuilles persistantes se propage par ses stolons. Ses feuilles, formant une rosette basale, mesurent 2-4 cm de long et 6-12 mm large. Elles sont spatulées, d'un vert clair dessus et d'un blanc cotonneux dessous. Les capitules apparaissent en mai, sur une hampe florale de 15-35 cm. Elle se plait au sein des pinèdes montagnardes.
