Scientific classification

Antennaria howellii (everlasting or Howell's pussytoes) is a North American species in the genus Antennaria within the sunflower family. 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.

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.
