Stoloniferous Pussytoes

Antennaria flagellaris



Endangered (Federal)
Red List (Provincial)


Stoloniferous Pussytoes are a small perennial plant that gets its name from its horizontal stems. These stems are up to 10 cm long, while the few central flowering stems are up to 3.5 cm tall. Its narrow leaves are 1 to 3 cm long and are covered with hairs. Flowers are grouped in heads at the tops of the stems and
produce dry fruits that are 2 to 3 mm long.


Stoloniferous Pussytoes most often grow in the Princeton area on eroded, unstable slopes that face south. These soils are saturated by groundwater in winter and dry up in summer. Not far from these sites, the vegetation is characterized by shrub-steppe dominated by big sagebrush with scattered Ponderosa Pines and Douglas-fir.
