Antennaria howellii, the everlasting or Howell's pussytoes,[2][3] is a North American species of plant in 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.[4]
Antennaria howellii is an evergreenperennial plant. The form is usually basal rosettes, largely clonally propagated. The basal rosetteleaves 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.[2]
Antennaria howellii subsp. howellii – western + north-central US, western + central Canada including Yukon
Antennaria howellii subsp. canadensis – northeastern US, eastern + central Canada including Labrador
Antennaria howellii subsp. neodioica – Canada, northern US
Antennaria howellii subsp. petaloidea – Canada, northern US
The plant is named for American botanist Thomas J. Howell, who collected the first known specimens of the plant in 1887.[5]
Conservation status in the United States
The petaloidea subspecies is listed as a special concern and believed extirpated in Connecticut.[6]
Native American ethnobotany
The Nuxalk Nation take a decoction of leaves for body pain, but not pain in the limbs.[7] The Ojibwe take an infusion of the neodioica subspecies after childbirth to purge afterbirth and to heal.[8]
